Hydraulic pump?

[WaxedElvis]

Bennett trim tabs - reservoir is properly filled and pump makes noise but tabs don't move. I loosened the hydraulic fitting inside the transom until fluid oozed out and ran the pump again to see if fluid came out under pressure. It didn't. Is it time for a new hydraulic power unit? Boatfix has them for $250.00 wanted to check before purchasing…thoughts?

Have you run through the Bennett Troubleshooting page?

You can also call the good folks at Bennett. They are one of a few good vendors left out there with outstanding customer service.

Didn't see the troubleshooting page when I went to their site - thanks - will try that.

Try jumping from battery + to the red (port solenoid valve)or the green(stbd s.v.) HPU cable connector pins afer you confirm both black wires provide satisfactory neg ground. You should be able to hear them click open. With connectors back together the helm tab switch should operate those solenoids with the pump. With the HPU top plastic cover removed you should be able to feel the solenoids on top of the pump operating when someone else operates the helm switch.
