Would someone with some knowledge of this boat please tell me what would be the appropriate size prop, including pitch with a 250 ox66 motor!
I just bought this boat yesterday. Last week, when I took her fir a ride the WOT was around 5400, @34mph. 50 gallons of gas and only 1 passenger, no load on the boat.DennisG01 said:I have a 15-1/4x17 on my boat - very close in size.
Have you run the boat? What's the WOT RPM, ideally with your normal load?
DennisG01 said:"17-M"... That is Yamaha's shorthand for the size. It's the same prop as mine. RPM is good - you're right up there near max.
Harpoon said:I would try the 15.75 by the 15P. I made that change from the old 17P on my F-stroke and it's great. Bigger diameter = more lift and lower pitch = more torque. These props were NOT available when your/my motor was made. But now you will see the performance tests for the 232 single use them. I was amazed the RPM's didn't shoot up out of range, this is likely due to the additional 1/2" diameter. Contact propgods.com they will point you in the right direction.
