Omc king cobra outdrive won’t go down

[fishonboat]

just as the title says it’s stuck in the up position. When trying to trim down the motor runs but will not budge. I even stood on it while my wife tried to trim it down with no luck. It’s stuck all the way up. It seemed to move a bit slow and it was working but was I trying to cycle the cylinders and after bringing it all the way up it wouldn’t go back down. Any suggestions? Thanks

Well I found a relief screw on the pump and loosened it and the outdrive went down and is working again. I’m a little afraid to take it all the back up again though. I guess if it happened again I now know how to lower it back down.

When ever you run the trim up run it down slightly to eliminate the high pressure in the system and it should work fine

you have a sticking load holding valve.

dont raise it against the stops and keep it there. as stated above, bump it down a bit.
