Thanks for all of the great advise on outboard motors. I have narrowed it down to 4 cycle, long shaft, 2 to 3 HP. Have any of you skippers used a special prop on the motor? Seems like the prop pitch and diameter needs to match the the shaft RPM, motor power curve and the M-15 haul speed. What is the haul speed of M-15? Since the Pelican is still in keel surgery I have no way to make a speed run. sincerely Captain Jim Sadler skipper sailing vessel Pelican M-15
