[C38] Great help

[Les Howell]

I have to talk about aims and hits here.  I aim for every year. I hit about 1.5 to two years, but generally my usage of the engine is pretty low, somewhere around 700 hours total since we got the boat.  This time the engine has 26 hours on it.  I have contacted my friend Brian Tansey to go through it with me.  And to see if there is another pump out there.  I just don't like the idea of opening the engine front to stray material.  Bad oil kills more engines than any other form of abuse. (except for water in diesel fuel).

    And I am getting clumsy (my wife says I just don't remember the last job I did ;-)...   So more parts off, more parts in the bilge.  My rule of thumb is if there are four parts involved I need 8, one of each to sacrifice to the great bilge god and one to get the job done. Sometimes if it is outside, the sacrifice is to Neptune.  

    I am a terrible swimming instructor, out of 100 tools I have taught, none have survived.

  Les,

  I had a Yanmar technician check out my engine a couple of years ago and he showed me how much easier it is to replace the raw water impeller if you unbolt and remove the raw water pump.  It is not necessary on my engine to disconnect any hoses.  Considering the poor access to the back side of my pump, it is the only reasonable way to service it.  Most of my trawler friends replace their raw water impellers once a year.  How often do you think is necessary?

    Hi, everyone,
        My head hatch lid is sprung.  Has been for some time.  Last week I was 
    going to take it off and work on it some, and broke the screw off in the 
    frame for the support.  So I want a new hatch.

        A very nice gentleman named JESS at San Diego Marine Exchange, has spent 
    literally hours helping me figure out what to use to replace it.  We now 
    have it down to two candidates from Bomar, which should fit the current hole 
    and meet my demands (which are that it fit the hole, Ha! Ha!).

        Anyway, wanted to give these guys a plug.  They are great.  I have 
    replaced my old Universal with a new M25 XPB.  The impeller is due for 
    replacement.  But the pump is a real (explective deleted) with a housing 
    that is bolted from the back, so you have to remove the hoses, remove the 
    mounting collar from the front of the engine, then remove the back screws 
    from the housing to pop it off the impeller.  Then replace the cover to the 
    cuff and rebolt it to the engine, and finally reattach the hoses (NO 
    KIDDING, this is the procedure in the manual).  A gentleman named FRED dug 
    out three differnet Oberdoffer pumps to try to find one that could be put in 
    place of this thing, but I don't have the original one off the engine yet 
    and the diagrams don't show lengths, etc.  So despite Fred's best effort we 
    couldn't replace the housing or the impeller or find a rebuild kit to fit. 
    But they suggested another shop down the street.

        Right now I will have to give San Diego Marine Exchange a real high 5. 
    So, please, if you need something, give these guys a call.  Their website 
    is: http://www.sandiegomarine.com/  And their prices are good as well.
