Motor tilt not working

After I was done with the boat today, I am back in the slip and I go to tilt the motor up and nothing. The solenoids are clicking (up and down) but the motor is not moving - at all. The fluid was topped off less than a month ago the day I launched the boat. It has been slow in the past, but now it is not moving. It is about 1/4 of the way tipped up only because the water getting to the slip is a little skinny, but that is where it is. I have a Mariner 150 1988 model year. Any info / advice is appreciated.

Thanks

Does the tilt motor run when you push the button??

If so the fluid may be low again or you have a internal leak of some kind.

If the motor doesn't run, Check the wires for a break to the T & T after the relays. Try putting power to the T & T motor and see if it runs.

Good Luck!!
 
i wouldn't hit the motor too hard, they have ceramic magnets that can crack if hit. I would check to make sure teh motor is or isn't running( previously mentioned), tehn if teh motor isn't running, check for power going inot and out of the selenoids, can't remeber when they changed it, but if your motor has three wires going inot it check teh black wire for ground, if it has two wires, the wires should be grounded when a solenoid has not been activated( it gets its ground citrcuut throught eh un activated solenoid). Then if nothing else works,, smack the motor ;D
 
It didn't sound like the motor was running. All I heard was the clicking of solenoids. I'll find out more today, but I have to be here at work for the next 8 hours.

Break out a 12V tester and have some one push the switch and follow all the way to the T&T motor and see were you lose the power.
If you don't lose the power all the way, you might be looking at a new T&T motor??

Carl, same thing happened to me when I put mine back on the trailer saturday. I reached under and tapped on it at the launch and it went up. I pulled the electric motor off when I got home (very simple, four long bolts) and opened it up. The contacts were just little rusty and one brush was sticking. I lubed it all up and cleaned everything with emery cloth. She is working smoother than ever now! ;)
 
yeah wack it with this ;D ;D

Carl: I had the same problem and found out that my brushes were worn out completely. If this is the case for you go to Mercrusier parts .com and you can get replacements there. I went ahead and replaced the rotor as well as the brushes and screws, and pump orings.


I did not want to take it apart again so I did it all while I was there.
 
Update:

I went back to the boat last Monday after work and the engine went right up.  Everything seemed to work fine.  I inspected as much as I could with the boat in the water and I saw the T/T motor cable was wrapped heavily in electrical tape. It has been like that for the two years I've had the engine.  I peeled off all the tape and found about a 1" split in the out insulation.  It didn't seem like the insulation in the conductors was compromised, but I'm sure water was able to get in.  I went backl on Wed, July 4, - gave it another two days to dry out and covered the opening with silicon.  I was hopeful that could get me through the season.

I took the boat out yesterday morning - everything seemed to be fine.  I fished for a few hours - picked up a 23" fluke - got back to the slip and - I hear the clicking of the solenoids but the motor is not turning.  I took Schools advice and tapped it and it slowly started to turn - and then had enough power to get the engine up.  I watched my volt meter as I did this and it seemed to droop about 4 volts with the T/T motor running.  I think its time to repair / replace the T/T motor.

That fluke made a good dinner last night with some sesame ginger sauce on it.   ;)

Ebay usually has a few listed just make sure you get the part numbers right and double check before you order as most places will not return electrical parts. I put one one my neighbors old yammahaha 115 a while back that I got for $118 plus shipping ...The dealer wanted $325...I'm probably going to get one soon for my 225 johnson as its starting to act up from time to time...Frank.
 
Yeah sfprovyn, that what I am trying to do. Unfortunately everything I have found on my particualr Merc - 1988 Mariner 150 hp - shows that the parts are NLA no longer available and don't give a direct replacement part. I definately don't want to order from ebay unless I am 100% sure it is the right part.

The hammer worked for me a few times as well.
Is this an I/O or O/B. Buddy had teh same problem and found it to be a problem with the lines.
Sorry I gave my old T/T away. :-[
 
Thanks turbinedoctor - I appreciate that.

It is a 1988 Merc Mariner 150 HP Serial # 0A906046

Model 7150726. It currently has the rectangular Eaton T/T motor.

Thanks again

Find a long established Merc dealer in your area. Chances are he has a pile of parts motors out back and can fix you right up. Thats how I replaced my T&T assembly.
 
if you have a good electrical shop around(starter and altenator place), chances are they can take it apart and clean it up to working specs for a little money if your remove the motor(tilt motor, not entire engine) and take it to them
