My 50hp Honda has been running well this season thanks to help on this forum! Anyways, one item remaining that I need to fix is that whenever I put the engine into reverse and give it some throttle, the engine begins tilting out of the water. When backing up I have to keeping pressing the trim down button on the throttle otherwise the engine will raise completely out of the water. I have twins Honda 50s on my 21ft seacat and the other engine doesn't do this. There must be something cross wired. Any ideas?
