1999 Johnson 250hp lifts in reverse???

[adm1476]

I have a 1999 Johnson 250hp on my 23ft cc. The tilt trim works excellent. However when I put the boat in reverse if I give it any throttle much above idle it lifts the motor up almost out of the water. What is the cause of this and can it be fixed? Sometimes I need to back down quicker than idle, and would like to be able to do so.

Exactly what to expect to be wrong... not sure. But that is a hydraulic system issue which should not be happening.

The tilt should hold the engine firmly in place. Just a couple of degrees of "wiggle" up or down.

Anything can be fixed. Somethings are cheaper/easier to replace than to fix. Not trying to be pessimistic... Someone may have had it happen and know a 50 cent part that fixes it in 5 minutes... I don't think it will be that easy.

There is a " reverse lock check valve " in the system.-----------If you do not have a factory manual a dealer can find that item.

Is the fluid at the proper level in the reservoir? If low, there may be air in the system

1999 should have the Fastrac trim and sounds like impact valve is stuck.Have you hit anything???

No I have not hit anything. However this motor is not new to me.
