<div>''The Catalina 34 has had at least three different engines. The<br />
* M-25, a 3-cyl, 21 hp engine, was installed on the the early models. <br />
* M-25XP (3-cyl, 23 hp) became standard in 1988. <br />
* M-30, a 4-cylinder producing 28hp, became an optional engine about the same time and is standard in the Mark II. <br />
<br />
All are produced under the Universal Motors brand (now Westerbeke Corporation). Due to lack of available supplies, the factory occasionally installed a Yanmar engine (note: Yanmars are higher-compression engines, which do not require glow plugs). ''<br />

'''[NOTE]''' The filter interchanges at the above OTT website can't necessarily be trusted; double-check if you use them. <br />
For instance, OTT lists NAPA p/n 3389 for both fuel and lube application. <br />
I brought this to OTT's attention and suggested they correct its list. OTT asked ME to provide THEM<br />
all the correct interchange numbers nd they would revise the website.<br> I don't THINK so. :-)<br />

<div>''The Catalina 34 has had at least three different engines. The<br />
* M-25, a 3-cyl, 21 hp engine, was installed on the the early models. <br />
* M-25XP (3-cyl, 23 hp) became standard in 1988. <br />
* M-30, a 4-cylinder producing 28hp, became an optional engine about the same time and is standard in the Mark II. <br />
<br />
All are produced under the Universal Motors brand (now Westerbeke Corporation). Due to lack of available supplies, the factory occasionally installed a Yanmar engine (note: Yanmars are higher-compression engines, which do not require glow plugs). ''<br />

* M-25, a 3-cyl, 21 hp engine, was installed on the the early models. <br />
* M-25XP (3-cyl, 23 hp) became standard in 1988. <br />
* M-30, a 4-cylinder producing 28hp, became an optional engine about the same time and is standard in the Mark II. <br />
<br />
All are produced under the Universal Motors brand (now Westerbeke Corporation). Due to lack of available supplies, the factory occasionally installed a Yanmar engine (note: Yanmars are higher-compression engines, which do not require glow plugs). ''<br />

<hr />
<div>'''The first part pertains more to M-25s with Oberdorfer pumps, than to M-25XPs -- but it's interesting background anyway... The second part pertains to us all with Oberdorfer pumps.....'''<br />
<br />
<br />
'''Here's the impeller/shaft mismatch, cir-clips stories....'''<br />
<br />
<br />
Grease cups are on engines with the Ob 202M-03 and 202M-07 series pumps (which were also used on some of our Universals), but no grease cups are on the 202M-15 and 202M-16 series pumps. ['''NOTE''' - more recently the grease cup on the side of the N202-03 and -07 pumps was replaced with a zerk grease fitting -kwkloeber 3 Jul 2022]<br />
<br />
<br />
Back in the heyday of a boat-a-day per boat mfgr, Universal bought whatever model pumps were available from whatever sources they could get them (OB, SW) and made do. Remember, "standard" is a word that the marine industry never embraced. So to meet the demand for engines -- remember 1 boat/day with "X" manufacturers = a crap load of demand for engines.<br />
<br />
<br />
So, Universal fabricated a special adapter plate and shaft adapter w/ male-male ends (3 pics below) to use the female shaft (M-03/07) pumps on some of our female-socketed Universals (our camshaft end has a female fork [see 1st pic below] to accept the male end of an optional hour meter on the Kubota tractors.) Yes, that's what the "pump land" on our gear covers is there for -- not a pump -- but a mechanical hour meter for the tractor.)<br />
<br />
[[File:25_adapter1.jpg]]<br />
[[File:25_adapter2.jpg]]<br />
[[File:25_adapter3.jpg]]<br />
<br />
When removing the pump impeller and shaft, it's usually a simple matter of reinserting/rotating the shaft/impeller until the male tang on the shaft lines up w/ the fork on the camshaft. But with the Universals that had the M-03/07 pumps, the male-male shaft adapter would remain inside the gear cover and then be misaligned when sliding the shaft/impeller back in (the adapter had to fit OVER the end of the shaft AND align with the female fork.)<br />
Because pump body blocks the view, one didn't know what the problem was, and blue streaks were oftentimes seen emanating from below and a purple haze floated above companionways along the dock. Luckily I had removed my M-07 pump first (not pulled the impeller/shaft alone,) so I saw the deal and never pulled just the shaft.<br />
<br />
<br />
== '''<big>'''About the Oberdorfer cir-clip "holding" the impeller on the shaft, here's the story....'''</big>''' ==<br />
<br />
Back in the dark `90s when I replaced my Universal adapter plate, male-male shaft adapter, and Oberdorfer 202M-07 pump - with an Ob 202M-15 model, my Engineer-side saw that the cir-clip holding the impeller was doing absolutely nothing. (I sure don't want to be hunting for my snap ring pliers in an emergency.) But the young-n-dumb diesel-engine-novice side said, "''Before I trash this clip, I want the expert(s') opinion(s') on why not to do that''."<br />
<br />
I went 'round n 'round with factory techs about the cir-clip and none could fabricate a reasonable explanation why it was there. <br />
--- ''"'''It holds the impeller in place'''''" <br />
('''Nah, not necessary -- the shaft rides against the shoulder on the impeller and the impeller floats against the pump cover'''.) <br />
<br />
--- "'''''It keeps the shaft in place'''''." <br />
('''Ok, try a different one, the shaft rides against the camshaft and it can't exit the pump'''.) <br />
<br />
As determined as they were with their bull, they couldn't get rid of the nagging question that begged for an answer -- "Why would Oberdorfer spend good money to machine a groove into the shaft and buy cir-clips -- unless there's a reason for it?"<br />
<br />
Out of sheer frustration I guess, or maybe to play a trick on a co-worker, they passed this idiot asking the unanswerable question onto another old-tymer's phone extension. <br />
It backfired -- he had been at Oberdorfer long enough and was honest enough to reveal the truth. Ob must have had issues with the pump shafts coming out whilst pumps were knocked about in shipping (nah, Brown wouldn't do that) and thrown about in warehouses (Really?) and the cir-clip holds the shaft in the pump until it's bolted in place.<br />
<br />
--- "'''''Yes you're right, <br />
'''it's unnecessary to have it on there and you can remove it ...but we don't tell customers that'''''."'''<br />

There are a few other items to consider besides cost: Size -- if you have installed a high output alternator, the filter length might dictate that a shorter filter be used regardless of brand. It’s imperative that some space be maintained between the head of the filter and the alternator adjusting arm. The shortest filter is the KUBOTA. Other short filters are NAPA 1356, BOSH 72182, FRAM PH6607, however, these are also smaller in diameter meaning there is less filter element. <br />
<br />
Clogged filter by pass: most (but NOT all) filters have a by-pass if the filter becomes clogged. The old saying, “dirty oil is better than no oil at all” is very true. This by-pass can usually be detected by seeing a spring on the inside of the filter which opens when the differential pressure reaches 11-14 pounds. You might also look at the filter and see a black rubber diaphragm under the small inlet holes. This is an anti drain back valve that keeps the oil from draining out of the filter when the engine is off (or when removing the filter). <br />

Per Racor - “From what I understand, the 2 micron branding on our filters is a leftover from pre NIST counting<br />
standards (from before Wally started here in 1981) and '''is more of a marketing name than a designation based on<br />
test data'''.” –Parker Hannifin, Racor Division 8/8/2012 email -<br />

'''''One of the very important things to know is the length of the belt. For M25 engines with the upgraded alternator bracket the length is 7400 or a tad shorter 7390 for Gates or Car Quest belts. The 7410 noted below may be a tad too long and the alternator bracket may bottom out and the alternator may hit the door.

<big>'''Here are RC's steps that he uses to flush the closed coolant system'''</big> (thank you, Rod!):<br />
<br /><br />
<br /><br />
If changing antifreeze, the best thing to do, especially if your engine had or has "Death-Cool" in it, is to thoroughly flush it out, clean it, and start fresh.<br />
<br /><br />

<br /><br />
<br /><br />
<big>'''To do this on a Westerbeke;'''</big><br />
<br /><br />
<br /><br />
1- Remove t-stat and replace cover housing using a spare gasket.<br />
<br /><br />
<br /><br />
2- Remove HX (might as well clean and have pressure tested.)<br />
<br /><br />
<br /><br />
3- Purge old AF out of engine with pump into 5 gal bucket.<br />
<br /><br />
<br /><br />
<br />
4- Use an acid resistant pump and circulate Rydlyme through engine block to clean cooling passages.<br />
<br /><br />

<br /><br />
<br /><br />
[[File:122459307.T0AFGsWf.jpg|400px]]<br />
<br /><br />
<br /><br />
The valve on the clear return hose in the bucket is to throttle the return in order to keep system pressure just below the radiator cap [''exhaust manifold pressure cap -kk''] blow point and to ensure all internals are cleaned with Rydlyme...<br />
<br /><br />
<br /><br />
Let this run for over an hour. Periodically opening the valve all the way to let any crud blast away.<br />
<br /><br />
<br /><br />
Keep the supply hose off the bottom of the bucket some.<br />
<br /><br />
<br /><br />
5- Flush Rydlyme with water then fill bucket with distilled water and circulate through engine.<br /><br />
Once the system is flushed with Rydlyme I flush it with clear water. It takes a lot. Probably 20+ gallons before it really runs clear.<br />
<br /><br />
<br /><br />
[''Note - Rydlyme is an acid (low pH) whose pH increases as it reacts with calcium deposits - so you can use pH paper to determine when it has 'worked on' all the deposits. Test the pH of the return flow at the beginning and periodically - Rydlyme is no longer 'working on' deposits when the pH stops increasing (reaches equilibrium.)'' -kk]<br />
<br /><br />
<br /><br />
6- Run 5 gallons of distilled through it and put her back together.<br />
<br /><br />
<br /><br />
7- Drain off what you can of the distilled, replace HX, t-stat and add antifreeze. The "Globals" are good. Death-Cool (AKA Dex-Cool) does NOT like all the dissimilar metals in marine engines and can create Dex-Sludge.<br />
<br /><br />
<br /><br />
Once back together add straight AF until the mix in the engine meets desired AF performance results. Leave the stat out until everything is bled and the AF mix is correct.<br />
<br /><br />
<br /><br />
8- Purge air and test AF concentration with AF tester.<br />
<br /><br />
<br /><br />
For air purging I replace the cheap "petcock" on top of the t-stat housing with a 1/4 turn ball valve. I then add a barb and some clear hose to it. Run the hose well higher than the highest point in the cooling system. Fill the hose with AF using a transmission funnel, open valve and start engine. As the t-stat opens and closes AF will gravity feed into engine and no air will be left in the system. Air=bad. <br />
Once the system is no longer taking AF out of the clear tube close the valve and drain the hose back into the AF container.<br />

<br />
I'm not generally a fan of terminal strips in the marine environment -- IF I can avoid them, I do.<br />
HOWEVER, if I can't, I use them judiciously -- in the proper locations (e.g., not an open terminal strip, in an engine compartment or bilge, hanging by a thread, no physical protection, wire/cable support/strain relief, etc.)<br />
<br />
THAT said, I have a half-dozen terminal strips for mast wiring to TV/RF to masthead instrument cables. BUT they are mounted in moisture-tight boxes with moisture-tight wire entries.<br />
<br />
I made my own setups with 4" x 4" x 2" Carleton (top) or Cantex (bottom) PVC junction boxes (from big-box building supply/online/Amazon etc.)<br><br />
[[File:box.jpg]] <br><br />
[[File:box2.jpg]]<br><br />
They have no openings for conduit or threaded blanks -- just a totally solid case w/ a gasketed cover, and mounting ears so they don't need to be compromised with a thru-case fastener hole.<br />
<br />
'''I tried several ways to get a moisture tight wire entry, but found this method was the best:'''<br />
[[File:barb.png]]<br><br />
*Get appropriate-size nylon male npt x hose barb adapters -- Grainger carries many sizes -- so I got a selection of several size npt/barb combinations -- up to 3/8" npt and 3/8" barb.<br><br />
<br />
*Drill & tap the box side for whichever nylon barb your conductor or coax cable will snugly pass thru (I typically use one barb per large wire pass-thru and combine multiple smaller conductors thru a single barb.) Dremel off excess threads so it sits flush with, not protruding much into, the inside of the box.<br><br />
<br />
*Screw in the barb, pass your cable or conductor thru, seal the wire entry w/ adhesive heat shrink tubing (AHST) around the hose barb end. '''Voila` - a moisture-tight connection'''.<br><br />
<br />
*Where you have multiple conductors thru a barb, tighten a small (4" flavor) zip-tie near the end of the AHST to mush the adhesive into the voids between the separate wires.<br><br />
<br />
*Mount a standard or euro type terminal strip to the inside box cover (w/ thru-cover, countersunk, flat-head, s/s machine screws/nylock nuts.) It's easy (even with fat fingers) to wire up the term strip with it on the cover vs. recessed into the box, and you can bury excess wire cable in the box to be able to pull the cover out and away to easily work on the strip.<br><br />
<br />
Those boxes also come in 6" size, and there are many similar inexpensive, gasketed solid boxes online in rectangular/round/whatnot configurations. Some w/ and some w/o mounting ears.</div>Kloeberenghttps://c34.org/wiki/index.php?title=(Moisture-proof)_Alternative_to_open-type_terminal_strips&diff=7426(Moisture-proof) Alternative to open-type terminal strips2021-06-09T21:31:00Z<p>Kloebereng: </p>

<br />
*Get appropriate-size nylon male npt x hose barb adapters -- Grainger carries many sizes -- so I got a selection of several size npt and barb combinations -- up to 3/8" npt and 3/8" barb.<br><br />
<br />

<br />
*Drill & tap the box side for whichever nylon barb your conductor or coax cable will snugly pass thru (I typically use one barb per large wire pass-thru, and combine multiple smaller conductors thru a single barb.) Dremel off excess threads so it sits flush with - not protruding much into the inside of the box.<br><br />
*Screw in the barb, pass your cable or conductor thru, seal the wire entry w/ adhesive heat shrink tubing (AHST) around the hose barb end. Voila`, a moisture tight connection.<br><br />
*Where you have multiple conductors thru one adapter, tighten a small (4" flavor) zip-tie on the end of the AHST to mush the adhesive into the void between the separate wires.<br><br />
*Mount a standard or euro type terminal strip to the inside box cover (w/ thru-cover, countersunk, flat-head, s/s machine screws/nylock nuts.) Even with fat fingers it's easy to wire up the term strip on the cover than recessed into the box, and you can bury excess wire cable in the box to be able to pull the cover out and away to easily work on the strip.<br><br />

I'm not generally a fan of terminal strips in the marine environment -- IF I can avoid them, I do.<br />
HOWEVER, if I can't, I use them judiciously -- in the proper locations (e.g., not an open terminal strip, in an engine compartment or bilge, hanging by a thread, no physical protection, wire/cable support/strain relief, etc.)<br />
<br />
THAT said, I have probably a dozen terminal strips for everything from mast light wiring to TV/RF to masthead instrument cables. BUT they are mounted in moisture-tight boxes with moisture-tight wire entries.<br />
<br />
I made my own setups with 4" x 4" x 2" Carleton (top) or Cantex (bottom) PVC junction boxes (from big-box building supply/online/Amazon etc.)<br><br />

<div>''The Catalina 34 has had at least three different engines. The<br />
* M-25, a 3-cyl, 21 hp engine, was installed on the the early models. <br />
* M-25XP (3-cyl, 23 hp) became standard in 1988. <br />
* M-30, a 4-cylinder producing 28hp, became an optional engine about the same time and is standard in the Mark II. <br />
<br />
All are produced under the Universal Motors brand (now Westerbeke Corporation). Due to lack of available supplies, the factory occasionally installed a Yanmar engine (note: Yanmars are higher-compression engines, which do not require glow plugs). ''<br />

<div>''The Catalina 34 has had at least three different engines. The<br />
* M-25, a 3-cyl, 21 hp engine, was installed on the the early models. <br />
* M-25XP (3-cyl, 23 hp) became standard in 1988. <br />
* M-30, a 4-cylinder producing 28hp, became an optional engine about the same time and is standard in the Mark II. <br />
<br />
All are produced under the Universal Motors brand (now Westerbeke Corporation). Due to lack of available supplies, the factory occasionally installed a Yanmar engine (note: Yanmars are higher-compression engines, which do not require glow plugs). ''<br />

<div>''The Catalina 34 has had at least three different engines. The<br />
* M-25, a 3-cyl, 21 hp engine, was installed on the the early models. <br />
* M-25XP (3-cyl, 23 hp) became standard in 1988. <br />
* M-30, a 4-cylinder producing 28hp, became an optional engine about the same time and is standard in the Mark II. <br />
<br />
All are produced under the Universal Motors brand (now Westerbeke Corporation). Due to lack of available supplies, the factory occasionally installed a Yanmar engine (note: Yanmars are higher-compression engines, which do not require glow plugs). ''<br />

<div>''The Catalina 34 has had at least three different engines. The<br />
* M-25, a 3-cyl, 21 hp engine, was installed on the the early models. <br />
* M-25XP (3-cyl, 23 hp) became standard in 1988. <br />
* M-30, a 4-cylinder producing 28hp, became an optional engine about the same time and is standard in the Mark II. <br />
<br />
All are produced under the Universal Motors brand (now Westerbeke Corporation). Due to lack of available supplies, the factory occasionally installed a Yanmar engine (note: Yanmars are higher-compression engines, which do not require glow plugs). ''<br />

For instance, OTT lists NAPA p/n 3389 for both fuel and lube application. <br />

<div>''The Catalina 34 has had at least three different engines. The<br />
* M-25, a 3-cyl, 21 hp engine, was installed on the the early models. <br />
* M-25XP (3-cyl, 23 hp) became standard in 1988. <br />
* M-30, a 4-cylinder producing 28hp, became an optional engine about the same time and is standard in the Mark II. <br />
<br />
All are produced under the Universal Motors brand (now Westerbeke Corporation). Due to lack of available supplies, the factory occasionally installed a Yanmar engine (note: Yanmars are higher-compression engines, which do not require glow plugs). ''<br />

<div>''The Catalina 34 has had at least three different engines. The<br />
* M-25, a 3-cyl, 21 hp engine, was installed on the the early models. <br />
* M-25XP (3-cyl, 23 hp) became standard in 1988. <br />
* M-30, a 4-cylinder producing 28hp, became an optional engine about the same time and is standard in the Mark II. <br />
<br />
All are produced under the Universal Motors brand (now Westerbeke Corporation). Due to lack of available supplies, the factory occasionally installed a Yanmar engine (note: Yanmars are higher-compression engines, which do not require glow plugs). ''<br />

See '''Service Bulletin #107''', Kubota Tstats likely won’t have a bypass hole, so drill a 1/8” hole, or two, thru the inside edge <br />
of its flange so there is a constant coolant flow thru the exhaust manifold when the Tstat is closed.<br />

* M-25, a 3-cyl, 21 hp engine, was installed on the the early models. <br />
* M-25XP (3-cyl, 23 hp) became standard in 1988. <br />

All are produced under the Universal Motors brand (now Westerbeke Corporation). Due to lack of available supplies, the factory occasionally installed a Yanmar engine (note: Yanmars are higher-compression engines, which do not require glow plugs). ''<br />

<div>''The Catalina 34 has had at least three different engines. The<br />
* M-25, a 3-cyl, 21 hp engine, was installed on the the early models. <br />
* M-25XP (3-cyl, 23 hp) became standard in 1988. <br />
* M-30, a 4-cylinder producing 28hp, became an optional engine about the same time and is standard in the Mark II. <br />
<br />
All are produced under the Universal Motors brand (now Westerbeke Corporation). Due to lack of available supplies, the factory occasionally installed a Yanmar engine (note: Yanmars are higher-compression engines, which do not require glow plugs). ''<br />

See '''Service Bulletin #107''', Kubota Tstats likely won’t have a bypass hole, so drill a 1/8” hole, or two, thru the inside edge <br />
of its flange so there is a constant coolant flow thru the exhaust manifold when the Tstat is closed.<br />
