Trim Stuck Up

Re: Johnson 85 HP tilt/trim won't go down

Tilt it up, engage trailer safety bracket, loosen the manual release valve on the port side mounting bracket (its set back inside a hole in the side bracket and you'll need a big screwdriver with a wrench on the shaft to break it loose....or an impact screwdriver)
Put a sawhorse under the leg and release the trailering bracket, does it drop? , see if you can cycle it up and down manually, do it slowly its not THAT heavy.

Engage safety bracket and check fluid again, refill.
Tighten manual release valve very tight and see if that did it.

I'm having the same issue. The motor will trim up no problem but when I try to trim down the pump will whine for a couple second and then go quiet. If I open the release valve it will go down no problem and will trim back up fine. When the motor is trimmed up I'm unable to cycle the motor down unless the release valve is unscrewed.
