I've got a question about my power trim on a 125hp mercury. The electrical works and the motor has hydraulic fluid in it. when i hit the trim up/trim down button on the motor or the throttle i can hear the motor working but the motor wont lift or drop...just wondering if it is a mechanical problem and what i should try??

notice any leaks? did you check the fluid?

Sounds like a check valve in the pump body.
Drag it down to G'mas, I'll fix it in about 10 minutes
