"I have a 1989 Larson Senza 21
"I have a 1989 Larson Senza 21' with a 350 mercuriser inboard/outboard. The motor is about 2 years old. It has a mild camshaft, an aluminum intake and a Holley 650 carb. I bought a remaned carb at the beginning of last season which seemed to begin the problems. I can be cruising fine at about 2,800-3,000 rpm's, if I go any higher in the range the motor will begin to shutter after 20-30seconds then come off plane. If I quickly pull back on the throttle it will pick back up and go about its business. If I don't pull back fast enough it will cut off. I can ski behind it and cruise just fine but when I sustain a higher than 3000 rpm it will shut down. I have replaced the fuel pump, pickup in the tank, filters, tried timing but nothing fixes the issue. I am going to pull the carb down in a day or so and see what is going on inside. I am a car guy so what jets should be in the carb. It seems to me like the carb runs out of fuel. Any suggestions would be great. thanks"
