Very helpful video. I used your troubleshooting process and found I had a stuck motor. I disassembled the front plate where the hydraulic hoses connect, then used a screw driver to turn the shaft. Now the trim motor operates in fwd, reverse and the solenoids both trigger. Thanks again.
Very nice explanation thanks. I need to fix my old Bennett HPU. Vintage 83 Team Scarab race boat. One side just clicks, other side clicks and motor runs. Neither tab moves. I'll check out the tab video also. Reservoir is full. Boat launches like the the Space Shuttle - in my case that means pointing straight up, haha.
The best course of action will be for you to email our support team at BMI_Info@Yamaha-Motor.com. The techs can help you diagnose the issue. They have a backlog at the moment so please give them a few days to respond. I'm confident they will be able to assist.
Dear Friends, The module Bennett Marine AR512 12V AutoTab Retractor is compatible with NEW Bennett Trim Tab Kit 48 "X 12" 4812E, or I have to buy other accessories?
Good evening, so I have new pump and when I apply power to the solenoids they are decent, but not loud clicks. The power to the yellow(reverse is strong) but the power to the blue(forward)is very weak. Fluid is full and have full battery and connections. Did I get a bad pump? Also, the test of sending power to one connector at a time isn’t affected by the trim tab lines correct? It’s in the boat not on a work bench. But the plug is disconnected
I’m having similar issue. Port side tab I hear when switched on but tab doesn’t move. It is stuck in the full bow up position. How do I test this on boat ..
Jimmy, please have a look at this video (ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-P3zmpXsuaH0.html) and see if that helps. If not please email BMI_Info@Yamaha-motor.com
The motor is not sold separately. You can go to just about any marine parts dealer or search the internet for a replacement hydraulic power unit. Part number V351HPU1 Tom McGow Bennett Marine
