Identifying OMC engine and parts when sticker is gone.

[jazzyjeff3]

I have a 1988 Four Winns 23.5 ft. with a 5.7 L I/O. The Power Trim Cylinders are leaking fluid. My mechanic needs the engine model number but the sticker has long been gone that was stuck to the engine. I have no idea, and neither does he, what the model number would be on such an old engine. I need to get parts to rebuild or replace the power trim cylinders that is leaking the power trim fluid. Any ideas???

omc usually stamps small numbers on the welch plugs of the power head for engine identification.

What does the number say that is on the plate on the outdrive, it will omc drive systems and a number. If you can find that out I will look it up for you and tell you. But to be honest if the boat is a 1988 if you look up parts for an 1988 5.7 cobra, you will be ok. The omc cyilinders were all the same for many years. Mike
