Prop help - 05/23/16 02:03 AM
I have a 17' aluminum boat with a 2000 Yamaha F80 four stroke motor. I am getting some small vibrations with the motor. It has the original aluminum prop which has some what I would describe as normal wear to the prop blades from minor dings and dents. I was thinking about replacing the prop to maybe correct the vibration and maybe gain a little more top speed. Where do I start when deciding on a new prop? I believe the prop that is on there now is a 13.5" but unsure of the pitch. Should I go to a stainless steel prop or stay with aluminum? Definitely don't want to do anything to damage the motor or put undue stress on it.
