I recently purchased a 95 Johnson Fast Strike 150 HP motor on the back of a Stratos Bass boat. The motor is mounted on a jack plate and the throttle is controlled by a hot foot. It starts just fine and idles perfectly and also cruises at low speeds just fine. The trouble comes at the high end when I try to take it over 40 MPH it will sputter a bit then completely die. Here is the kicker it will work just fine at high end if I pump up the ball every single time I start the motor, that includes after I stop and fish for a few hours. I have to pump the ball until it is very hard and tight, but it does not seem to hold pressure. I have replaced the ball and the previous owner does not have a clue what is going on since this didnt happen to him at all. He did replace the fuel filter right before I purchased the boat. Any suggestions would be great!
THANK YOU!!!
