Trim Issues Please Help

[Brent Christian]

I have a late 80's xr6 blackmax 150 hit my trim switch both up and down and nothing but a loud click? Any suggestions? Motor I guess bled off and is now setting on ground so now I can't even move the boat? Would appreciate any help.

There is a screw in the side you can turn to open the trim bypass to raise/lower the motor manually.  As for the click, it sounds like the switches and relays are working. Probably should see if the trim motor has a fuse or have the trim motor checked out.

On my 1980 merc.115,where is the by pass screw?I don't see it anywhere.If I unscrew one of the screws on the cylinder it lets out the oil,which will allow the motor to go up and down manually.That's the only screw I see.

I would think it would have one and there is usually about a 1/2" hole in one side of the transom mount. Look up in that hole and you will see a screw slot.  I have seen some that had allen screw heads though.  Turning it CCW will bypass the hydraulics. 

 

I'm just going by where they are usually at, I have never had my hands on that model in particular so I can only guess.  The early ones had remote pumps, and they may have put it on the pump unit.

Lets check a few things first.  Check your battery voltage and have the batteries load tested, if you do not feed the circuit with enough voltage or amperage you can have trouble.  Check the ground connections on the engine.  The clicking you hear should be the relays located under the engine cowling. I have heard of some instances where water got into a trm switch, shorting the circuit and lets say activated the trim solenoid in the down position until the battery wore down.  Sometime that burns out the trim motor. Get a manual, identify the trim relay, check the power going to that relay when someone activates any of your trim switches.  If all is okay there, trace down to the wiring going to the solenoid.  using some wire jump the power down to the solenoid.  The trim motor should activate if the problem was in the wiring/switches.  If you give power to the trim motor and nothing happens you probably need a trim motor.  If you do not feel comfortable mucking in the wiring, check with your dealer about the pressure relief, raise the motor , then off to the dealer you go!
