Main Message Board / Weeping bleed screw fixed
« on: July 04, 2005, 08:53:04 PM »
A while back I posted a question about fuel weeping from the bleed screw on my secondary (M35B engine mounted) fuel filter no matter how much I tightened it. I now have solved the problem. There is an 8mm. soft copper washer under the screw that gets flattened after it has been tightened a few times and has to be replaced. Had a bit of trouble finding this washer but finally succeeded. Problem solved.

Main Message Board / Missing limber hole?
« on: June 13, 2005, 08:55:32 PM »
I recently found a little water on the forward side of the bulkhead supporting the forward berth. I then noticed that water was collecting there because there was no limber hole joining the forward compartment to the central bilge area. Therefore, if the forward water tank sprang a leak, for instance, the water would rise up to the level of the small inspection hatch in the bulkhead supporting the forward berth and run across the sole before hopefully spilling into the bilge aft of the mast step. There is a limber hole visible at the aft end of the mast step.

Are all the Mark IIs like that or did my forward limber hole get lost when the bulkhead was being tabbed in?

Main Message Board / Windlass up the mast
« on: June 06, 2005, 09:03:37 PM »
I needed to go up the mast to replace my dead deck light bulb so I pulled the main halyard bitter end out from under the dodger, reversed the direction of the block at the base of the mast and lead the halyard forward to a snatch block attached to the base of the Schaeffer furler with a line and then down to the windlass drum. Kate used her toe to winch me up the mast effortlessly. The windlass is worth its weight in gold!

BTW, the lense on the dead 20w reflector bulb can be removed and put on to a new bulb/reflector with a little clear sealant thereby increasing the life of the bulb.

I did some reading on windlass loads in preparation for this adventure. The Maxwell VC 500 has a maximum static load of 1000 lbs. My claw anchor and 200 ft of hi test 1/4" chain weigh 183 lbs. The West Marine windlass advisory suggests that the maximum load on the windlass should accommodate at least three times that weight (549 lbs). The Maxwell would appear to be appropriately sized for the boat. If only I could figure out how to check the oil level in the sucker without removing it I would be a totally happy camper.

Main Message Board / Sticky Marelon thru-hull
« on: May 17, 2005, 09:14:24 AM »
All the Marelon thru-hulls on "Calypso" turned easily except the large one for the engine raw water intake. So I backed off the four bolts that hold it together about a half turn each and the movement of the arm became smooth but still firm. Problem solved.

As I recall from taking one apart many years ago, the thru-hull is a sandwich of pieces of Marelon and o-rings that could easily have been assembled a bit too tightly. I am assuming that as long as the body of the fitting doesn't leak and the valve functions properly (i.e. stops water when closed and vice versa), then one can play with the optimal tightness a bit. I notice that Forespar warns against adjusting the bolts on its website but I am guessing that they are just trying to guard against some moron loosening the bolts to the point that the body of the thru-hull begins to leak water into the boat. Any views?

Main Message Board / On the trail of Kubota
« on: April 14, 2005, 08:30:41 PM »
I have been trying to establish the Kubota engine equivalent of the M35B so that we can all go off to our Kubota tractor dealer and buy subsidized (kidding!) engine parts. I started with a posting from Roc on the C36 site which said that the Kubota no. on the side of the M35 is Model: V-1305-E. I tracked that number to the Jennings Equipment site where the V1305-E turns out to be a 3 cylinder engine. But  I discovered that the Kubota V1505-E2-D21 is installed in the Kubota B3030HSD "premier tractor". The V1505 is 30 hp, 4 cylinder, 91.5 cu. in displacement, bore and stroke 3.1 x 3.1 inches, and takes 4.3 litres of oil.  Could be our guy! It is also installed in the Kubota Compact Excavator, KX71-3.

Then I think I confirmed that when I discovered that Witchard Marine in Oz marinizes the V1505 and calls it the WM 35. The picture looks just like our Universal M35B. See:  

The excitement builds! Plenty of data on the engine here which makes the match pretty air tight. Even the gear box (Hurth HBW100) matches up.

See performance data for the engine @

Oops, a setback in certainty. Another Kubota site says the V1305 is a 4 cylinder as well (not a 3 cylinder) and the preformance data is also close to our M35B. Roc may have been right after all. See:
But then a further Kubota site makes it pretty clear that the 1305 and the 1505 are basically the same engine. See:

So I think we are closing in on it. What we need is someone who has specs for the M35B at home to check them against the specs for the 1305 and the 1505 and close the deal. Then I can get my tractor hat on, go up to the Kubota place on the Saanich peninsula and check prices.

Anybody else want to pick up the Kubota challenge?

Main Message Board / Bleeding secondary fuel filter
« on: April 03, 2005, 02:28:39 PM »
I appear to have small amounts of fuel leaking from my secondary fuel filter cannister. I have tightened the filter so I don't think it is the connection to the block. Has anyone experienced a leak from the joint between the body of the filter and the screw on top?

Since I have to change it regardless, I did a search on the bleed technique. I could not find a definitive answer re whether or not the fuel pump would purge the air from the new secondary filter on its own (with the filter bleed screw open) or whether I have to purge air from further along in the system as well.

Has anyone with a M35B done this job?

Main Message Board / Autohelm clutch problem
« on: March 30, 2005, 08:51:40 PM »
Here is an interesting little problem that I hadn't run into before despite years of autopilot use. I went to disengage my Autohelm 4000+ recently and it wouldn't. The very small rolled ss pin that connects the clutch handle to the cam had sheared and the handle went back and forth without doing anything. Trying to extract the remains of the pin I split the handle. A Raymarine agent sold me a kit with a new handle, cam and pin for a ridiculously high price. The rolled pin proved impossible to insert without a special tool. Plain ss pins sheared off after a couple of days. So I drilled out the incredibly small hole through the handle and cam to a slightly larger size and I am now happily using a small ordinary nail to connect the handle to the cam. Seems to work fine. The nails cost a dollar a pound!

Main Message Board / M35B heat exchanger end cap
« on: March 08, 2005, 03:46:11 PM »
I noticed a crack in the removable end cap of the 3" heat exchanger on my 99 Mk 11 when I took it off to fish zinc bits out of the exchanger. When I got the replacement cap from Westerbeke it was quite different from the original simple flat 3" bronze cap. To start with it was about 1/4" less in diameter and had a ridge all the way around the circumference that  presses into the gasket. My mechanic checked and Westerbeke insists it is the new, improved replacement. I have put it on and there was no leak when I ran it but it seems strange to have an end cap that is smaller than the end of the exchanger body it is bolted into.

Anyone else run into this? Any problems with leaks?

Main Message Board / Kubota equivalent
« on: August 18, 2004, 05:21:48 PM »
Does anyone know what the Kubota equivalent of the Universal M35B engine is? If there is an equivalent, are parts generally cheaper if you purchase them from a Kubota dealer?

Main Message Board / oil change
« on: August 10, 2004, 02:39:19 PM »
I just did my first oil change on Calypso, #1431, a MkII with a Universal M35B. I could only suck 3.5 quarts of old oil out and, put about the same amount of new oil back in. All this despite the engine manual claim that I should be taking out and putting in more than 5 quarts.

I did a search on this issue and found a debate about the correct amount but no obvious consensus around a particular number of quarts.

Does anyone have a definitive answer (or at least one based on some experience and/or communication with Westerbeke)?

Much appreciated

Main Message Board / Replacing standard Jabsco toilet
« on: August 01, 2004, 02:01:33 PM »
Does anyone know if the standard Jabsco toilet on the MkII is attached by lag bolts so that the old Jabsco toilet can be removed and a new Jabsco bolted on without having access to nuts/washers under the attachment point?


Main Message Board / Noise suppression and the yellow wire
« on: June 03, 2004, 10:14:43 AM »
Is there an audiophile in the group? In the course of exploring the electronic bowels of my new (to me) boat I notice that the previous owner installed a Pyramid 20amp noise suppressor as part of the aftermarket car audio system. A couple of questions. Is this device necessary if I don't run the audio system when the engine is on? Second, does it draw much power? It seems to be powered from a small secondary breaker panel with 3 amp plug in fuses but I haven't been able to sort the whole scene out yet.
 A related audio question. There seem to be two power connections to the am/fm/cd unit. One is the red wire which goes to a breaker on the main panel and the second is a yellow wire  which goes directly to the house battery connection on the main battery switch. Both are fused. What is the purpose of the yellow wire? Why is it connected directly to the main battery switch and is that the best way to do this? The readings on my e-meter suggest that even if the battery switch is turned to the starter battery, the power for the audio system continues to come from the house battery. Is the audio unit effectively being powered through the yellow wire?

Main Message Board / Puget Sound bound
« on: July 05, 2004, 09:40:21 PM »
Kate and I are off on Friday for three weeks south of the border in Puget Sound and the San Juans. We will keep an eye out for other C34s enjoying a summer cruise. Please feel free to drop by if you see us "wasting away" in your favourite anchorage.

Main Message Board / Alternator bracket
« on: June 24, 2004, 01:21:39 PM »
I need a longer reach on my alternator bracket to handle the larger Leece-Neville alternator installed on my 1999 Universal M35B. Has anyone found a good source for after market alternator brackets? I was hoping to avoid grubbing about at the nearest auto wreckers yard...which isn't actually that near. Ideally I would like to find a bracket which was about an inch or so longer and was the same curve as the OE or slightly flatter. NAPA doesn't have anything.

Main Message Board / Vented loop for toilet
« on: June 06, 2004, 08:24:42 PM »
Hold your nose for this one...
 I just read the Jabsco toilet manual which came with the boat (it was raining...I was reorganizing the bookshelf)and I noted that the Jabsco people insist on a vented loop in the  hose line between the toilet and the holding tank if the toilet discharge elbow (at base of pump)is not at least 8" above the top of the holding tank. The manual isn't graphically specific, but I assume that the vented loop would stop the bad stuff from returning to the toilet when sailing hard on a starboard tack.
 Now for the bad news. There is no vented loop in my discharge hose and the toilet discharge elbow is quite a bit lower than the point on the holding tank where the discharge hose from the toilet connects. Does anyone else have a vented loop in their discharge hose?  I recall that my c320 lacked a vented loop and I am pretty sure that the discharge elbow was well below the point where the discharge hose entered the holding tank. No problem in 9 years of sailing.
 I breathlessly await assurance that all is well...or otherwise.
