Re: High Thrust Prop for Tohatsu 9.9 on Nonsuch 22

By using a high thrust prop such as the Tohatsu 10"Dx7"P I was hoping to gain efficiency (more thrust at lower rpm) and do a better job of matching the motor to the hull speed of my boat (max. 6 knots).

Also by using a 4 bladed/elephant ear prop that almost no rake in the blades I believe I would relaize more thrust/control when the motor is switched to reverse.

Most outboards I see as auxillary motors on sailboats are "high thrust' variations with four bladed props that have have a ptich between 5 to 7 inches.
