I have a 1994 Kawasaki TS and it won't stay running while in water. When its on the trailer out of water it runs great. Good throttle response and sounds good. But once you place it in water it acts like it bogging down and stalls. It runs a little bit longer if I raise the seat up but as soon as I shut it, the motor stalls. Any help or recommendations would help. I don't have a clue where to start! Thank you!
