I want to buy a propeller for a 20'boat (searay) 4.3 v6 merc crus. what do you recommend?

Question

I don't know is stainless good or should I go aluminium,composite?Love to hear from ya.

Answer 1

Stainless is costly and bends very easily.

Answer 2

I have a composite prop and it feels like it bends under load. Also , they can't be cupped so i had to trim the motor way in and slow down just to make a turn. I bought a cheap Hustler aluminium to replace it and it performs brilliantly. They're already cupped so you can trim your motor out and make nice tight turns without any cavitation. I only bothered with a stainless steel prop for my racing boat (26" chopper ) , for normal use , you won't notice the difference in performance and it'd take years to make up the price difference in fuel savings.

Answer 3

If in hard bottom aluminum > SS is all I use as the hold up the best>Cost more but if you touch something the blades don't break off & you can get back to the dock>>
