i have 2004 35 ex when i first got the boat they worked fine.the trim switch stuck in the up position when i stopped.then when i went to go they would only go down.the problem was the up solinoid's were burned out.replaced them and worked but not even.when i use the rocker switchs to the left if i make the starboard one go up they both go up when i make it go down it works fine.same thing with port,please help!!!!!!!!!

I would hook up a volt meter and check to see how the motors are getting power when you push the toggle switches. A solenoid may be stuck or the wiring may be wrong, or?

Usually this is from air in the hydraulic system. A quick way to be sure is to bleed the system and this can be accomplished very easily. Run the tabs all the way up and hold for about 5-10 seconds. If there is air in the system you will usually hear a screech or whining type noise. Whether you hear it or not, run them all the way down and hold again. repeat two or three times and see if solved. Let me know, I'm curious. Thanks.

There are two slightly different types of solenoids, if you hold them side by side you can see the difference in the plunger. That may be the cause, your best bet is to mail Tom at Bennet he is extremely helpful and will have the correct answer.

A P.S. the switches do operate the opposite side tab, this may seem odd but it is correct. It in effect make the boat do what you are thinking, you want to roll it to the right the left tab must go down to the left the right tab must go down.
