I have a 1990 40 hp with a trim assist cylinder.
That means that my trim does not work. It has been stuck in the down position since i picked up this boat about a year ago. I under stand that this in not an uncommon problem. My question is has anyone came up with a solution that doe not cost $500? If you look on the used market, the power trim system is in high demand, and typically will run you north of $500. I have found two aftermarket systems, both run over $500. What have you guys came up with? Maybe addapt a Mercruy trim unit, or one from a differnt year Johnson or one from the three cyclinder Johnsons? :confused:

That seems to be about the price for having that trim. If you look long enough, you might find something for less, but that's the only way.

Re: 40hp trim solution

I have the same year 40 hp johnson motor and when i bought the boat the assist didn't work as well. I found a way to rig the cylinder so that i could move the motor up and down by hand. This is a way cheaper option to buying a new assist cylinder. On the cylinder itself there is a cable that is connected to a pin that locks the motor in position. What I did to correct the problem was remove the cable from the cylinder. Once you remove the cable take a pair of pliers and lift up on the valve that the cable was connected to. You should be able to move the motor up and down easily then. I took a washer and cotter pin to keep that valve in the open position. The only downfall is that you can't lock the motor. It has worked for me for 6 months now and I haven't had any problems.

Good Luck

The valve on my motor is very hard to lift. I do not know if this is normal or not. My question is how did you manage the reverse problem? With the valve in the open position, I would expect that motor will jump out of the water if you put it in reverse and give her some trottle. This is very dangerious! What is your solution Matt?
