I can't figure out the firing order for the "right hand" - counter rotation - Mercruiser 351 Windsor. Anyone know. It's seems that the firing order in the Iboat online manual contradicts or doesn't include the specific right hand order.
Thanks,
WW

A very hard to find diagram...thank you! Follow up question... in a twin screw, which engine would be the L.H. (port?) and which would be the R.H. (starboard?)

To correct the above statement, the starboard engine is the LH rotation engine (standard rotation) The port is the RH rotation engine (reverse rotation). You always determine engine rotation by looking at the flywheel end of the engine.

Welcome to iboats toyboy
Best to start new threads with your questions, too many people answer the original question without reading the rest, not realizing it's well over a year old, and that there are new questions.
