Motor tilt not working

[Carl]

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

bad tilt motor tap it with hammer see if it responds

[macojoe]

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

Then if nothing else works,, smack the motor

LMFAO!!

[Carl]

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

I got one of those in my tool box, works everytime! ;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.

[Carl]

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.

Carl

[Skools Out]

ask Lefty if he still has his extra tilt trim section aka Hammer lol

[msbhammer]

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. :-[

[turbinedoctor]

What is the model number of your motor and any other important info. I will see what I can find if you like.

[Carl]

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

Carl

[Airslot]

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.

[spareparts]

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

[Carl]

I plan on pulling the boat tomorrow after work. *I'll get her home and take apart the T/T motor and see what it looks like and go from there. *My fish finder depth sounder was acting up as well as the brand new *digital fuel meter *>:(. *I'll take a look at them too and see what gives. *

[turbinedoctor]

Check out this link. I think I got the right motor for you. If so it looks kinda pricey.

Hope this helps.

Seen a few used one's on E-Bay, rams encluded.

[turbinedoctor]

You can get a few good deals on ebay but I like knowing I am dealing with a reputiable company when it comes to items like this. I would hate to go through all the trouble to remove and replaced one of these just to find out it don't work.

That's my $.02 worth on it.

[Carl]

Alright, I brought her home tonight and started to take apart the T/T motor. I got three long screws out of the top, but cannot even get a screwdriver on the last one. The one that is still in is the aft most starboard screw. You can see it in the 2nd pic. I'm sure there is a trick to this. So I attached some pics of my situation and maybe someone can point me in the right direction.

Thanks

Carl

[spareparts]

you have to take that side of the transom bracket off, its a PITA, I've tried a long screw driver from every angle, ended up striping the screw head

[turbinedoctor]

Well did the boat fall on you or something, what the status on the repair. ;D

[msbhammer]

Been there and done that. Take off the left side of the engine bracket and remove the whole T/T. If ya remove the right side, you might be forced to remove the steering cable and make more work for yourself.
Let us know how it works out for ya. *;)

Hey,

I'm still here and the boat hasn' fallen on me yet. I got the old motor off after removing the bracket. I took off the right one hopefully it won't be too bad to get back on. I found oil between the motor and pump and the motor had a nice burnt smell to it. Two of the four brushes in the motor were totally shot and the other two were not very good. There is a really good chance that the pump may have a bad seal also. I have been calling around because there are very few of this style motor. There was only one on ebay that fit my year. It was the pump and motor assy. I found a place that had one in stock. It was also the assy. He got good coin for it, but he was cheaper than ebay and fairly close by if anything doesn't work out. I will install it tomorrow. Last night was the local 4-H type agricultural fair and tonight was the big fireworks show, it is always a good time for the family. I will let you all know how it goes as soon as possible

Carl

[Carl]

Alright, Some news to report. I have replaced the pump and motor assembly. It wasn't too bad, with only a few glitches along the way. Mostly just moving up the learning curve for this being my first time for this job. I also found out that the down solenoid is acting up. So tomorrow, I will pick a new solenoid - maybe both since I figure the up solenoid is probably not too far behind.

Good news on the fuel transducer also. I called Northstar (previously Navman) and they are sending me a brand new transducer to connect to the digital meter and display. It should be in the mail tomorrow. This is part of the F210 Northstar fuel monitoring system.

The only other item I need now is a new fish finder / depth sounder. I had a cheapo Humminbird Piranha 1 - I paid about $60 a few years ago which has decided to run erratic and shut itself off more times than not.

Here are a few pics of the new motor.
