Hey Fellow Catalina 34 owners;
I need some help determining which engine is installed in my '86, C34, Hull 233...I was told it's a Universal 25...But when attempting to order a folding prop, found out there are 3 models of the Universal 25, all with different horse power ratings...
The engine does not have a label plate on it which specifies the model, and the original owner/factory left the information blank in the owners manual...I have looked on the engine to try and find the serial number, but could not; I did find lots of numbers which I believe are individual part numbers, not the serial number.
I also e-mail Robert @ Catalina for help but have not received a response...
Can anyone tell me if there is a way of determining which model I have by looking at the engine??? i.e. is the water pump, oil filter, or any other part in a different location on the different models???
Or can anyone tell me EXACTLY where to find the serial number???
Thanks for your help,
Tom
I know of two models that Catalina used in the 34, the M-25, 3 cyl 21 hp, and the M-25XP, 3 cyl, 23? or 25? hp. The M-25XP is a bored out M-25, with the stronger alternator bracket, and a larger (3") heat exchanger. I believe that the M-25xp was used in the third year or so. If your engine is original, it should be the M-25.
Our #224 has the M-25. Steve's right: if you have the 2 inch heat exchanger, it's an M-25. You may have the newer alternator bracket since many folks did that necessary mod.

It's just aft of the thermostat housing, in the forward section of the engine where you add oil. It is a label that has the model number and serial number.
