1978 daytona 19' . Went from iron tall deck to 9.850 aluminum. Anyone out there went from an iron motor to an aluminum one with more power. Tried to post video but it wont let me. It goes from overcharging to running out of water with minor adjustments. Cant seem to complete a pass without it bucking. I would think this new lighter motor would like more shoe, but the opposite, I had to pull some shims out cause intake pressure shot up till ass slowed down & water finally burped out the back. Motor sets 30" from transom , Does it need to be moved forward ? I'm loosing my patiance. Help....anyone ?
