So top quality boat driving skills I have managed to hit my prop on some
rocks. One prop is chipped and one is bent about .5 inch on the end. Boat
doesnt have any extra vibrations but top speed has gone from about 40 to
30mph.

I called around to some boat shops asking about repairing the prop and I got
prices ranging from $100 to $140. For that price I would assume I can just
get a new one and keep this one for a spare.

Question is what kind of propeller do I get? My boat is a 1987 sea ray
19foot with a 1987 165hp mercruiser inboard/outboard engine. The current
propeller has 3 blades. Besides that I dont know much about the propeller.

Hopefully there is some guide out there that tells you what size/pitch prop
to get. I would like one that is suited better for top speed than for
acceleration.

Thanks for any advice!
