Propeller Fits Mercruiser

I need to know if a propeller from a Bayliner bearing part # 48-78120-19 will fit my Mercruiser outdrive.?

I have a 96 Wellcraft Excel 21S with a Mercruiser V6 and Mercruiser outdrive. I'm looking for a new(or used) prop to fit. I found one on Craigslist that came off a Bayliner. Part # is 48-78120-19. Will it fit my boat or do I need to keep looking?

The problem you're running across is that Bayliner only makes boats, not engines and outdrives. Depending on the year and age you could be looking at either a Mercruiser or a Volvo Penta engine. You need to find out what engine is installed and then see if it's the same as yours.

From personal experience, it won't be. Even if the brand is the same they change these engines and outdrives so often that the odds are slim that this will fit. I don't know about your Wellcraft, but with the Bayliners it's usually cheaper to throw away the engine and outdrive, reinforce the transom and install an outboard instead. At least with an outboard you can just swap one engine for another with confidence.

Good luck with your search..
