1991 sunsport

runs great out of water.....but in water bogs down when try to get on plane.......anyone had this problem.

Holley 4160 - rebuilt
gas tank drained cleaned
fuel pump cleaned.

The boat has been in storage for 7 years, so i cleaned everything and took it for a spin. 1st trip went great...ran strong but at the end of the day started to bog down on occasion.

2nd trip.....again ran fine....drove across lake and sat for awhile....then when started back up......bogged down on way back to ramp.

Driveway tests - runs strong----steady at 3000 rpm and strong bursts to 6000-6500 rpm.....runs great

3rd trip - week later

engine fires right up.....taxi thru no wake zone.......give it some throttle and nothing.......bogged down....

Any help would be greatly appreciated....
