i have rebuilt the carb and cleaned the jets in it the air fuel ratio needle is set and everything runs and idles just fine but in nuetral it will rev up but in forward with a couple people in the boat it will bog down the compression is good and its getting enough fuel but when i put my hand in front of the open carb it will get on plane and haul down the lake full throttle or when i choke it any suggestions?

Sounds like you need to clean your carb again.. especially if choking it helps once warm. Be sure to replace the 5/32" fuel line from fuel pump to carb, as ethanol blended fuel may be drying out the inside of the hose and sending gunk to your carb. There's no screen past the fuel pump, so any debris goes straight to the carb. Good luck!
