mercury 150 trim and tilt

Has any one changed the trim and tilt assembly on a 87 merc 150, Do you have to pull the motor?

What’s wrong with it?

It bleeds down while running and will not trim all the way up under full power. I have a new/rebuilt one in hand and will be installing it in a couple weeks. I have 2 tournaments two fish before I can put it on.

Looking at the Service Manual for that motor, it shows how to install a rebuild kit for the trim motor. For that the motor and trim motor stay on, but it looks like you can remove the trim motor without removing the entire motor. You’ll want the motor tilted all the way up and slide an steel bar through between the mounting bracket and the motor for support, and they also recommend using a hoist attached to the prop shaft as a “fail safe” to support the motor – that’s a lot of weight that could drop on you when you remove the lines on the trim cylinder if something goes wrong.

Good luck.

Thanks Dan!! I decided to install a jack plate on my Charger so I will have to remove the motor for this anyway.
I found my service manual and have not had time to read it all the way thru. I sure will prior to starting the install.
