In this video I test the performance of a PowerTech! Red 3 13.25 x 14 pitch propeller. This prop is the same size and pitch of the recommended Yamaha Prop for Classic Boston Whaler 17's powered with Yamaha F70 (actually an F70la) outboard engines.
Comparisons were done in as close to identical conditions as possible. 10 Gallons of fuel on both runs, 350 pounds of payload (Me and my son). In all comparisons, the engine was trimmed as far up without porpoising. In case you are wondering, engine is mounted three holes up which is what is recommended for the classic Montauk 17.
Here are links to the props mentioned in this video, the links to the props are NOT monetized. I especially like the propdepot folks, Fast free shipping and best price by far of any dealer!
