Bubba, I have a 1993 14ft. Sylvan deep-v (15 in. transom) that I put a 03 Yamaha 25 hp four stoke tiller( 20 in. shaft) on in Sept. Even though I was apprehensive about the weight the marina that I bought the motor from said that my transom was rated for the thrust of a 35 hp motor, which is the max rating on my boat. They put a jack plate on to adjust the difference and that just added more weight. Now the water line is about 7 ins. from the top of the transom, if I go in reverse too quick water splashes up in the boat and I have a huge rooster tail when I am running on plane. When at rest my keel is'nt even in the water. Is there anything I can do to fix this problem without going through the headache of selling this motor and getting another one? I thought about putting a hydrafoil on it to try to balance out the boat but it's obvious that I don't know what I am doing lol. Any help would be great. Thank you Sir.
