    I tilted my Yamaha 115 motor up to move the boat before the Hurricane hit.

    now the motor will not come down. So I used the pressure screw to make it come down.

    it is going, Click, Click, Click. Won't go up or down.

    So I cleaned the battery terminals, plenty of current.

    I took the cover off of the motor and took the green relay wire off and touched it to the positive it should have went down, I also touched the blue, it should have went up. nope.

    could be the motor or the relay?
    need to research a little more.

    I removed the Relay, brought it in the hose to test.

    Just checked the continuity on the relay they are all working fine.

    that means that it is the tile motor.
    but before I replace the motor, I will make sure by testing with a new battery. Sometimes clicking means low battery.

    Charging now.

    seems like I have a good charge, perhaps it's a bad wire?
    if not the Trim Motor?
     
  4. Great job diagnosing the issue
    Is replacing the tilt motor a big job.

    Blocking the motor up so that I could jack it up was the hardest part so far.

    Started the job with jack and landscaping stone.
    not the best.

    Got smarted and derided to use cinder blocks
    worked out great.

    Got it to the point where I could get the working safety support brace down in the locked position
    so that I could work on the trim motor without any chance of the outboard coming down on me.

    trim motor to the left, four bolts holding it on.

    removed all blocks, hoping to lower the motor by self trim motor power when done .

    going to wash the trim motor area so that no sand or dirt gets into the fluid when it is removed.

    Just read an article about trim motors armature carbon brushed getting stuck.

    So I went outside and tapped on my Tilt motor with the handle of my screwdriver, and it started work, got stuck again, then I tapped some more, and this time it went up and down a few times.Since I do not want this to get stuck up or down while on the water, i'm just going to replace the motor. them open and examine the old one ad fix as a spare.

    The armature alone runs $393, yet the whole motor assy is just $4 more. Usually when these motors are going they are just replaced.

    So I ordered a new Yamaha aftermarket trim tile motor, should be here this week.

  7. Nice savings on the aftermarket part!
    Too bad you didn’t see the article about the brushes until after you stacked those blocks.
    Let us know how the replacement goes. Good luck on a smooth installation

    I'd defiantly look into rebuilding the old motor by replacing the carbon brushes and you'll have a spare motor on hand. Easy rebuild for a small cost.

    I had my trim motor changed out due to it drawing too much current. Went with a api aftermarket rather than oem Yamaha due to cost. Thanks for sharing the experience changing it out.

    OK so I started working on replacing my trim motor this morning, got it half done, and here comes the rain... at least i got three bolts on, one fell behind the motor, will have to play around to get it out, looking for my Magic...

    before I started, I clicked the switch with the motor unbolted, the motor turned, then stopped working again, glad I'm replacing it...

    here are some pics

    Installed an O-Ring supplied with the motor, then installed the motor.
    here is the new trim motor bolted on...
    back left bolt fell and is wedge behind it...
    this will be fun trying to fish it back out?

    raining hard out side right now, job now on hold...

    I was hoping to get this done, so I could go get some Mango's and reds... my freezer needs a few. LOL

    OK Rain stopped, ran up to Home Depot to get a socket drive joint to put the back bolt back on. Tightened up the bolts, ran the wiring and reconnected them, flicked the switch up and down works like a gem.

    took a few pick for this post.

    Definitely good being able to do the work yourself. At least you save the money and you know it’s done right. Thanks for sharing

    Excellent detailed post. A hydraulic engine hoist would probably be just the ticket for the initial block-up.
