The carb was rebuilt . Clean as a whistle. The issue started before the carb was rebuilt. For a 2001 model, it probably only has 12 hours of use sense new. Sat in storage most of its life. I drained the fuel & flogged the cylinders before storing the ski. Ski has fresh fuel. I bought a new fuel filter for it. I don't believe thats the problem sense the ski runs perfect out of the water.This is due to the back pressure that is applied to the engine while in the water through the pump. Same reason that the trailer idle stepped is twice that of in the water idle speed. What is the condition of the carbs and fuel delivery system? When was the last time they were cleaned?
Try pulling the choke when it dies. If it picks up there is something wrong with the fuel/air mix.
Yeap, If I pull the choke the engines starts to accelerate. Then dies. My guess is that it maybe a fuel pump issueTry pulling the choke when it dies. If it picks up there is something wrong with the fuel/air mix.
