Re: [Amel Yacht Owners] Repower

Kent Robertson

My Volvo never got to maximum rpm until I re-propped, but after re-propping with a prop that was sized and pitched according to a prop shop in Norfolk, it did 7.5 kts at 2800rpm on flat water.  With my 110 Yanmar it does 8.3 kts at 3000rpm on flat water.  Not really significant since I don't run it that hard when motoring or motor sailing while cruising.  At 2200 rpm it pushes the boat at about 6 kts.

Thanks for the info Chris. It looks like 80 hp is the way to go on our older boats due to the Cdrive issues.
