I believe there were some Westerbekes in between the Perkins and
Yanmars. Here is the info I have been able to collect. I would like to
update the transitions, so if you have a boat in between, let me know
what you've got!!



1995 Hull 181 Perkins M30

1996 Hull 327 Westerbeke

1998 Hull 488 Yanmar 3GM30

Does anyone know when Catalina changed from Perkins to Yanmar?
<br><br>And, for anyone with the Perkins M30, the exhaust elbow is not
custom made.  It is a Perkins part and can be purchased from
www.foleyengines.com and perhaps www.tadiesels.com.  This is a cast iron
item and seems sturdy enough.  Our engine is 12 years old with nearly
1,000 hrs.  I recently had reason to check the elbow, and while there is
some carbon, it seems quite clear.<br><br>Running the engine for very
short periods, or long periods at low rpm will cause carbon to build up
faster than if run at high rpm.  Perhaps fuels with higher sulpher
content or lower cetane ratings will produce more carbon.  I have been
adding a cetane booster to my fuel on the advice of an engine mechanic.
If fuels in your area are below 40-45 cetane, perhaps you should
consider using a cetane booster.  They can be bought at any auto supply
store or truck stop.<br>!!-
