I purchased a used Pontoon several years ago with a '87 60hp Mercury. At the the time the trim tilt/trim were not electrically operational and a piece of allthread was used to keep the motor in place ata a specific angle of sorts. I decided to fix the elecrtrical system by installing a three position switch for up off down. The trim/tilt work but I noticed when I put the pontoon in reverse the motor bounces up and down. It did not bounce with the all thread rod in place previously. I tool the pontoon out of the water and checked out the tilt/trim system. I noticed even though the trim was down, I was able to lift the motor by hand quite a bit. I then raised the motor all the way and was able to push the motor down quite a bit but not all the way. A replacement unit sell for $1200 however it is an upgrade i.e. they no longter sell the older complete system. I am considering rebuilding the tilt and trim cylinders. Any problems or gotcha's I need to be aware of? Any other thoughts?

Re: Motor Bounce in Reverse

The cylinders probably need to be rebuilt but first make sure the bypass valve is closed. Look for a large screw head on the assembly and make sure it is tight in a clockwise direction.
