This problem just started out of the blue. It didn't give any initial problems before. And it happens time i put the boat in the water. So it will do it when cold or after running awhile.
Here is what i know:
When boat on trailer:
1. The up and down function works fine on all 3 locations of the boat.
2. The motor will hold up without leaking down for 1 day so far.
3. The motor will lift up with me and my son standing on the lower unit fin, roughly 400lbs.
4. I can't reproduce the motor going down on the trailer.
When in water:
1. While in water sitting still, the up and down works fine.
2. While in water sitting still, the motor will hold up without leaking down.
When in water driving:
1. When i am going slow the motor will trim up and down.
2. When i am going almost at breaking a wake, the motor will not trim up.
3. When getting on plane, motor will not trim up. If i trim it up from a stop then try and get on plane, it will go down.
4. If i trim motor up from a stop and "punch" the throttle it will go down.
When driving on plane:
1 When i am on plane, i can see the trim go up and usually it will hold.
2. Down works fine on plane.
I don't have any issues with the down part. It is my up side that doesn't move or hold under pressure of acceleration.
Is there any orings i need to check the the valve body? If so can someone tell me where and what to check. My boat and motor is a 1999 Bass Tracker with a 90hp Mercury outboard, same year as boat. Thanks
