Wonding why it work not installed and not work when installed........Kinda Stuck


Thank You

Figured it out........ Maunufacture defect the motor and pump are seperate and the motor drive shaft the keys into the pump to drive the pump is to long and it binds up in the pump and wont turn. returned to manufacture and got new one works perfect.

Good for you sometimes a little time helps.

I've got a 5.0 L mercruiser alpha one. Had to replace the pump on mine. Also replaced the two solenoids. Took pictures of it before I tore it down so I know everything is hooked back up correctly. I got it all back in the boat and the pump worked up and down perfectly. A few minutes later I tried to trim up and got nothing. It will trim down. But when I try to trim up I get nothing. No clicking or any noise coming from anything. All wires are intact and everything is tight. After messing with it some more I noticed that the 20 amp fuse was blown. Replaced it and still can't get it to trim up. I can jump the solenoid with a screw driver and it will trim up just fine. Just won't work using the trim switch on the handle. Any suggestions???
