Starter Power Trim Solenoid Compatible with Mercury Mariner Mercruiser Outboard Motors 12V 4 Terminal 89-96158T 89-846070 89-94318 89-818864T

Fixed my trim on my 1990 Bayliner capri.

This unit appeared well-built, solid and heavy, like the original. I tested it and it made a nice click when activated and the primary resistance went to 0 like it should have. Not the unit's fault, but it was difficult to install due to the design of the oildyne trim pump in the Mercruiser I have. The down solenoid is placed such that it is pretty much impossible to get at the rear mounting bolt of the solenoid. After some trying, I had to remove the battery and unbolt the whole pump unit and tilt it backwards without spilling fluid, then I was able to get a box wrench ontp the rear mounting bolt and with 1/8 turns, was able to remove it. and install the new unit. Then when attaching the wire to the new unit, I found I couldn't use the old nuts on the new unit, the threads and nuts on the new unit were metric. Since I was on my knees the whole time, I had to get up and go get metric wrenches. After that, and some time making 1/8 turns tightening the rear mounting bolt, I was able to attach the wires and test the unit (using the second battery) and it worked fine. Then I had to reinstall the pump mounting bolts and the battery. It was a long process, all on my knees. But the bottom line is the solenoid was fine, all the =is extra work was due to the design of the oildne pump. I didn't want to get into disconnecting the hydraulic lines and removing the pump assembly to get access to that rear mounting bolt. But on youtube, most guys do that.

The old solenoid finally gave up. This part was a direct replacement and worked perfect after installing.

smaller than original but works fine
