What prop for a 8MSHS?

[SailingMel]

I just bought this 1994 Yamaha 8 2 stroke. The prop is really bad...been ran through sand and a rock by the way it looks. It is a 8 1/2 X 7 1/2, 7 spline. I checked this site and they only have 7 and 8 pitch. Both list my engine on the list. How do I know which one would be best? it will be on a 9.5' hard bottom inflatable. Any advice would be very helpful...

Thanks.

or google it, also my try youtube.

Without a tach (even a tiny, small or chinese tach) you'll never be sure if you have the right prop for your boat/motor.

The rev's for you motor must be 5500rpm or close at WOT.

If you need more help let us know.

Good luck
