Location: Chicago, Beverly | I have a Tuffy Rampage with a 40hp evinrude. I use two props on it, I have a 12 3/4"X15" AL and a 13 1/4"X17" SS. I get more top end out of the SS prop, but am unsure of my rpms with it so mostly run the 15" especially in rocky or stumpy waters... MY SS is a Michigan Wheel, and the AL is a OMC prop. I had the AL cupped by Air Marine and it did make a difference.... I get just over 30mph average GPS with the 15" with a max of about 32mph and a max of about 34-35mph with the SS 17"... I would only go composite like others said, as a get me home spare prop.. |
