[QUOTE="nashua fisherman, post: 214956, member: 2192"] you cant tell from the angle of the picture but the cavatation plate IS level with the bottom of the boat. this is just the initial setup. i used 3x3x1/8" 6063 aluminum. i used this websight to figure my prop slip; https://go-fast.com/Prop_Slip_Calculator.htm 2.23 gear ratio, 9" pitch, 5940rpm, actual speed was 21mph. i dont think theres much more speed in there since even @6200 rpm with 0 slip the speed would be 24mph. im gonna clean up the prop when i figure how. ide like to get more speed with 2 people in the boat. also, i had to trim the motor all the way up to hit 21mph. this caused the boat to do crazy wheelies when taking off untill it planed.
