M25XPB Engine Info

[Stu Jackson]

A friend with a C34 has an M25XPB engine.  Not too many C34s have this engine.  We'd corresponded and here is my reply to her.

Carolyn,

Geez Louise, we met one time for a lunch and now you have me waking up in a cold sweat!!!

I just realized, about a half an hour ago (i.e., 0630!!!) that the link for engine filters I gave you was to our C34 tech wiki which is for the M25 and M25XP engines and NOT your M25XPB.

Sorry about that.  I keep forgetting you have a different engine.

So please ignore those filter equivalents, they may not work on your engine.

Instead, and to make up for my error, please use these links for your engine.  I shamelessly stole them from the C310 skippers on www.catalinaowners.com.  You have to scroll up to the top and the start of each of these linked posts, since the links below take you to a particular post within a longer thread.

One of the contributors in those links is JK Boston Catalina 310.  His name is Jesse.  He's their technical editor and a really nice guy who has documented a lot of work he's done on his boat.  He wintered over in Boston (YIKES!!!) and will be leaving soon for the Bahamas.  He knows his stuff.  He has his own blog here:

For engine issues, you should get to know him.  If you have ANY engine problems, he's the guy to contact, NOT me. :-)   You might want to get to know him well enough to do email direct.


This is another M25XPB story I ran across during this "investigation," it's always something to keep in the back of your mind for future reference:

Finally, Engine Bleeding for the M25XPB:

Good luck, sorry about any confusion I may have caused you.

Best regards,

25, XP, XPA, XPB, 35A, 35B use the same oil and secondary fuel filters.

Stu : The only difference between an M25XPB and an M35BC engine is ONE less cylinder!! 

Otherwise, everything else (internal workings, bleeding, etc) are all the same.  Both have the ZF10 transmission.
