Bennett Trim Tab Pump

[petem]

My trim tabs (and also the engine hatch ran that utilises the same pump) are very slow.

Does anyone know what causes this and what can be done to restore performance?

You've probably already thought of all these, but I'll list them anyway. I have no specific knowledge of the bennet trim tab pump (had one on my old boat, but it was fine) , just coming up with generic things that could cause you issue

-low battery voltage, either through worn out battery or (maybe more likely) corroded connections?

-maybe corrosion inside the motor itself on theelectrical connections , or buildup of dust? Maybe it just needs dissasembling and a clean.

- worn pump motor itself, maybe worn brushes?

- a seized bearing on the motor leading to increased friction?

Fouling on the trim tab hinges.
Low oil level in the reservoir.
Low voltage on the pump.

Have you checked the fluid level ?
