The Yamaha Painted Stainless Steel in the 13" x 17" size works well too, as does the Yamaha Performance Series in the 13-1/4" x 16" size. Be sure the motor is NOT mounted all the way down on the transom. It should be one hole up for the Painted Stainless Steel model and two holes up for the Advantage or Performance Series models.

On that prop it will run right to 5700... with 2 adults and a full tank... Can't explain the big difference, but that what I see... Jon in NJ Many other boats and outboards in my boating history The Whaler is the one I like the best!!!

The motor is mounted 1 hole up and the boat performs perfectly well. My guess is that 2 holes up might give it a bit extra performance since the boat runs very level at higher speeds whereas I'd like to see a bit of rise at the bow. I'll give the 2 holes up option a try next season.
