Ric,
    I have I 4 cylinder universal that may be the M-35. It has given me good
service altho with a racing boat I only have 825 hours on it. Why did you
get rid of it? Joe Launie, Macavity

Hi Patrick,

 

I had a universal M35 in Legacy (before the Yanmar I now have) and it had
two bolt-on end caps on each end of the heat exchanger.  It was pretty
simple to remove them and clean out the small tubes inside.   There were
rubber gaskets between the body of the exchanger and the end caps that
looked like they were cut from an old intertube.   I cleaned my heat
exchanger out a few times as there was a zinc electrode in the heat
exchanger that would disintegrate and clog the small tubes with broken zinc
chunks.  

 

I don't know if any of this applies to your engine.

Skippers,

     I wrote and appreciate your answers/help about impellor breaking up and
engine over heating.  Then there was the problem of the black smoke
emanating from the engine compartment.  Someone mention it might me rubber
parts of the impellor getting into the heat exchanger? 

Does anyone know how to access/clean heat exchanger?

Thanks,

Patrick..aka  "Blue Eyes"
