Fiber Tri hull listing to port

[anaconda44]

My 16' fiberglass tri-hull outboard has a list to port when under power. Sits level when not moving. Played with the trim tab both ways with no effect. Tried under different wind directions, no noticeable difference. Not a huge list, but very noticeable.

My boat has chambers under the floor in case the boat were to take on water. (Newer ones use foam to keep the boat from sinking.) There are small thermos plugs at the back by the drainplug to let water out if it gets in there. If you have those, the port side may have water in it.<br /><br />Do you have a whale tail on the motor? Try taking it off.

No plugs, motor wings not on at this time. I thought about water under floor, but it sits level when sitting still.

man i have the same exact problem on my 15' tri-hull. ive ruled out water, imbalance and hull deformations. no trolling plate either.

do you have a bent hydrofoil fin or skeg?
