Mark,

This is from the WAY OLD pre-Forum/Main Message Board days, but there's a lot of valuable information there.  Frankly, I'm amazed I can still remember that some of them exist!  :)

http://www.c34.org/faq-pages/faq-mast-pumping.html

This is from this page in the Tech wiki:

FAQs

http://www.c34.org/faq-pages/faq.html

The intro on that page explains where the content came from.

>>>>>>>>>>>>>>>>>  it does not have a sump.
 It pumps directly from the shower drain.

Bill,

Perhaps it is just terminology, but many of us consider the shower drain to BE a sump because there is a small "sump" (box) right below the drain.  It ius shown  in the boat manual in the plumbing section.

Hi and welcome.

Heads were supplied by different vendors and may not be the same on all Mark II boats.

What brand of head do you have?

We've found that the more specific you can be in the question the higher degree of probability of a useful answer.   :D

hull 99 1986, i can't remember what i do to get water into the head. >>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>> i did open what i thought was the seacock - the valve is in line with the hose.  i remember there was 3 things to open.  thanks

becki kain

becki,

When in doubt, check the boat manual:  http://c34.org/wikiwp/?rdp_we_resource=http%3A%2F%2Fc34.org%2Fwiki%2Findex.php%3Ftitle%3DManuals

Look under plumbing, there's a diagram showing the OEM three thru hulls under the head sink.

Review those below and see if you agree, or can you see where something differs?

Ken,

I wrote that over a DECADE ago, oddly enough literally to the day!  :D  IIRC, at that time, the referenced diagrams were from a manual that was online here, in Reply #49 of that topic, which may well have pre-dated the major expansion of the wiki.  That link no longer works.  The differences were as I described.  There appear to be no compelling reasons for me to attempt to find those two particular pages again.  IIRC, I was on vacation at the time, so had to rely on that online linked version, which I printed out, analyzed and then discarded.

You're certainly right about the two diagrams you posted.  Same numbers, too.  As you've pointed out, it wouldn't be the first time that there may have been errors in documentation.

And thanks again for helping with that wiki expansion by posting a much more thorough set of manuals.

Further to my earlier post Reply #4, this is what I was referring to in the Critical Upgrades topic thread:

In 2007 we had discussed this in a very looong thread:  Hard Starting/ Possible glow plug problem?? M35 Engines & Fuel Pump Wiring

http://c34.org/bbs/index.php/topic,3347.45.html

Reply #54 on page 4 of that topic begins to discuss the wiring to the fuel pump, how it works, issues with bleeding...


I just looked at it, try starting at the top of the page, Reply #52 is longer and gets into the nuts&bolts.

That thread discusses the very wiring diagrams Ken has so helpfully posted.

One VERY IMPORTANT take away from that discussion is that there are two wiring diagrams that purport to show the same thing.  IIRC, they may well be the same number diagram, 200360, that Ken posted.  [It IS, see Reply #47 in the link.]  They are both in the manual.  One is a schematic, the other shows physical relationships and connections.  I discussed the differences between these SAME NUMBERED DIAGRAMS  in the link in this post.  It is CRITICAL when looking at them that you understand the differences, in addition to Ken's observations.

Roland,

I don't know what Marti may have had in mind.

But I kept reading the posts on that topic when I found it yesterday, and would follow our Technical Editor John Nixon's guidance in his excellent post further down the page.

Is there any information on the comparative reliability of the brick style NAPA pump 610-1051 ($53) and the referenced purolator gold flo pump (about $150)?
>>>>>>>>>>>>>>>>>>>>>>

Roland,

Since you know the "Magic Number" for that pump, I'd have thought you'd seen this, part of the topic that introduced those pumps:

In the long run, I suggest you do as Ron did and scrap that stupid "Westerbeke's better idea" system thru the oil switch.  if you want to bypass that "temporarily", I believe that you can tap into the alternator field excite wire (12v powered off the key switch) and power the fuel pump.  I will verify that when I can study the schematics.

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

Ken's right.  IIRC, there's a post in the Critical Upgrades, concerning "Hard Starting" and the glow plug/oil pressure stuff (http://c34.org/bbs/index.php/topic,5078.msg41829.html#msg41829)  that discusses this very issue and provides a link to a much longer discussion about this very issue that is not specifically about the XPB either - it pertains to other engines, like the M35s.

I agree with Ken, Wb's idea leaves some room for improvement.  Like Ron did his: the old way!  :D

Just in relationship to your pre-1930 Mark I diagram.  Sure been makin' C30s a loong time.  :D  They had sails and engines back then?  :D:D:D

Rego Park...wow...long time ago in a galaxy far, far away...

In addition to the locations of our C34 systems bearing no relationship to a C30, our water heaters are connected differently to the coolant circuit, not via the HX loop.  Ken, you must remember our parallel series recent conversation?!?  :D:D:D

The top of the pump is almost right at if not a smidgen below the WL.

anybody wanna find out, just take the faceplate off with the thru hull open.

I'd do it, but I just rebuilt and reinstalled my pump.  :D

If you're going to go to the trouble of opening that screw, have you considered simply then opening the rw thru hull until water comes out the hole?

SO one thought is the thermostat which is old...could replace it.
Another thought is a small blockage into or of the HX or possibly the elbow. I had the HX serviced 4 years ago at an alternator shop however.

>>>>>>>>>>>>>>>>>>

Please weigh in with any thoughts/suggestions.



Tom,

Don't tear your hair out quite yet.  :D  Your systematic approach should be applauded and continued.

Ed wrote about our experiences with HX inlet ports.  They sometimes block up with salt precipitation.  I have been recommending removing the HX every two or three years, yourself, when you have the downtime, and check the ports.  It's rarely the tubes.  We have no idea what "service" from an alternator shop could be, but I'm sure you could tell us.  In any event someone took it off.  If you did, we figure you looked closely at it.  If not...:D

It is also rarely the elbow.  The water gushes in thru that nipple pretty quickly.  The welds and the risers break first.

Thermostat?  Who woulda thunk that'd be my next culprit.  Got nothin' to lose there either.

Stay with it, keep us posted.
