Default Same old question....

Here's tested props. Didn't have a 17 to test....

1985 Wellcraft v20 Fisherman CC
Closed Transom with Stainless Marine Bracket
Yamaha F150

Fuel topped off at 60 Gallons
2 batteries (unfortunately in the stern)
Full 20 gallon in deck livewell (unfortunately in the stern)
Boat is a tad bit *** heavy....

Prop RPM MPH GPH

Mercury Vengeance
14.5 x 15 -5700- 36 - 14.2
Cruise - 4260 - 24.4 -8.7
4.5 seconds to plane


Yami 3 blade SS Black (old)
13.5 x 19- 5600 - 36.2 -16
Cruise - 3800 - 25.4 - 10
6 seconds to plane

Spoke with Power tech dude. He recommended a OFS3R15 3 blade 15 1/4 x 15

or a OFS4R14P (15 1/4 x 14) 4 blade.

Anyone running these dimensions for a prop and what do you think?

Thanks
