Hi. I have a 1992 evinrude 175hp. It needed a pump motor when I got it. I pulled the whole trim/tilt assembly off and changed the motor. While on the bench, I filled it and raised it. Tried to lower it and it won't go down. I am using test leads directly to a battery, so I know its not a relay or switch issue. I can get it to lower by unscrewing the relief. I can then raise it but when I switch polarity the motor runs but it won't go down. I then took everything apart sprayed it out with brake cleaner and air, reassembled and still the same. Questions: Does it need the weight of the motor to go down? I found a complete outboard (1996 evinrude 150)... Will that trim/tilt assembly fit my 92 175? Thanks for any help. Jon
