" I just recently purchased a 1972 15' 4" Chrysler boat with a 70HP outboard Model 707HF. When at full throttle the motor tends to jump intermittently. The motor sounds like it doesn't miss at this point. If you watch the motor when it does it, it wants to lift up. It seems to do it more when there is more weight in the boat or turning(when thee is more load on the engine). I read about cavitation in the manual and tried tilting the motor at differnt angles but it didn't help. The prop is in bad shape and am the process of repairing or replacing it. Could the prop be the cause of the problem? It seems to be happening more frequently as time goes by. "
