Check the gear ratio. It could be different. Otherwise, it's the same drive.

I think the ratio for those engines were the same some years. 1.43:1 comes to mind.

It will work fine though. You may need to put a slightly "taller" prop on it though. Run it first. then try different props. You can find (good even SS) props on ebay all day long.


Cheers,
