Hi
I have a 1974 Sportsman I am going to re-power and would love to pick your brains on what you experienced.
I'm going for a 300HP Mercruiser Horizon inboard 350. She'll fit nicely but the rotation is different than the 318Chrysler. So i need to change props. The 1 1/8" diameter shaft is okay.

When you re-powered, did you have to go to a left hand rotation prop?
Did you upsize the prop?... stay with a three blade? Stainless, brass or aluminum prop? What prop specs can you provide? diameter, pitch, prop make?

Thanks
