[QUOTE="Attwanl, post: 361337, member: 10236"] I just put 9.8 hp nissan 4-stroke..., it has a 7 pitch prop. I was looking on the Nissan website and found this chart. *Definition of Loads Light: 100-500 lb. Pitch 9 Moderate: 500-1500 lb. pitch 8 Heavy: 1500-3000+ lb. pitch 7 Ok with boat, motor, fuel, fishing gear, cooler dog, me and wife we don't hit 700lbs. It's on a 12/36 flat bottom. It gets on plan pretty quick, don't know top speed but it clips along no problem. But it does seem to peak out and I can lower the rpm's and it doesn't seem to affect the speed. ( I think it might be reving a little high at wot) My question is will changing the prop from a 7 pitch to an 8 pitch make that much of a difference? Or will it be a waste of time and money? It is a big change from the 6hp Evinrude 2- stroke I had on it. Thanks for any input. [/QUOTE]
