[QUOTE="lowe1648, post: 317774, member: 6349"] As rude as said before it's worth playing with motor height. Not as easy with a 225 as are small motors. I started playing around with the height on mine. I started out at the beginning of the day running 27 down river with two of us. After moving my motor several times I can average just under 31 and saw 32 once or twice but after running it at that height for a few trips I need to drop it. I do not have any cavitation in tight turns or straight line but it will in chop or if I slide at all and then the pump won't hook up right away. I don't have power t&t. I originally set my motor height with the motor tipped in as close to the transom with the leading edge of the shoe even with the bottom of the hull. After running it I decided the 3 hole out from the transom had the best performance. Checking where the shoe was with the motor in that position was slightly below the bottom of the hull. That was my original setup which was set down on the transom and right now I am 3/4" higher now. I'm going to drop it a 1/8to a 1/4" and think it should be perfect. I don't know how practical it is to adjust your motor height but if your mounting holes will allow it would be worth a afternoon. [/QUOTE]
