confused about my motor

[jlcjtc]

I have got a 20 ft renken 1987 ski boat 2050. This is the first boat I have ever had.I am looking for a manual so that I can service and do repairs on my engine. The thing is I am confused about which manual to get. In the block of the motor it says GM, on the carb is rochester, and on the manifold it says OMC, 4.3. Will someone tell me what I have, thanks

Re: confused about my motor

You have all three <br /><br />Buy the OMC manual. OMC converted the GM engine for marine use. The manual will also cover the carb.
