Boomer, you have any other suggestions on the tilt motor thing I have brewing? Motor runs good, turns gears steady etc, until I put the weight of the outdrive on it. Then it's sporatic. Good battery, filled clutch case with 4 cyc oil, (change to grease later once I get it running good). New O rings, gasket on cover. Even the guy I bought my parts from told me hates troubleshooting these tilt motors. Sometimes a little push helps, most of the time no. Don't want to fry the motor constantly trying!!!!!-Jeff<br /><br />1981 OMC 400 GM 2.5 litre.

Re: OMC tilt troubles....still (Boomer, you there) ?????

If i remember right, Your tilt motor is a new one that was used correct?<br />If so did you check to make sure it was putting out enough torque? I tested mine by placing the motor in a vice. Then, with a torque wrench with a flathead mounted to it on the end of the motor and activated it. The torque wrench was one of the non-clicking type with a pointer on it. When the motor was activated, the torque wrench would show just how much torque force was being generated. I am not positive on the number but i think it was like 25lbs.

I did not test the torque. Yup I bought the used motor. I have been told that if the clutch assy held the o/d up and or down, the clutch was torqued. Is that a typical problem with these, even if it worked fine before the new motor, and the clutch was untouched as far as disassembly?

Re: OMC tilt troubles....still (Boomer, you there) ?????

jh, 78fw, is talking about testing the torque on the motor not the clutch pack. A recent conversation with my local OMC guru revealed that a tilt motor, having been impregnated with oil, may not be able to develop sufficient torque. He refuses to sell used ones (which he has plenty) for that reason.<br /><br />I'd test it too be sure. The torque value is 27 Inch Pounds, not foot pounds.<br /><br />Did you inspect the inside of the motor, looking at the brushes and commutator?? Sometimes you just need to clean those up and rescribe the goo out of the commutator segment cuts.

Not a chance! I'll have to have someone else do that for me. I don't have the stuff, the time, or most importantly, the know-how for that! Sounds like you may have the right idea though. Sometimes it goes, and sometimes just a click.

Anyone have any place in eastern Mass that could do this type of work? (Boomers suggestion). Thanks-Jeff

Re: OMC tilt troubles....still (Boomer, you there) ?????

I'm about ready to! In all seriousness, where the hell would I bring this for this kind of test and cleaning. I would imagine any engine rebuilder (one about 4 miles from my house) could do the test, but what about the rest? I'm trying to watch the $$$ I'm of the school (auto) of forget rebuilding your own alternators and starters, buy a new one. But obviously the marine ones are so much more costly. If you have an idea that yu want to send to me, or if you really want to do it yourself, send me a message at mnehky@yahoo.com

Re: OMC tilt troubles....still (Boomer, you there) ?????

look up starter and alternator rebuilders, in the yellow pages, in your area. They can certainly inspect, clean, and do the electrical tests on it. Not sure if they'd have the torque wrench to do the torque/draw test tho. It's simple enough to do. They just have to lock it in a vice, hook the shaft to a torque wrench and put the juice to it in both directions. <br /><br />I'd test it for ya only the shipping would cost you a few bucks and the turn around would be about two weeks with ground shipping. Try the yellow pages. It's just a motor, if they know the specs I would hope they could test it. If not I'll do it.

I still do not think your new motor is bad in the first place. Wish I could help you further.<br /><br />I feel your frustrations really I do. I have some of my own right now trying to retrofit a new set of manifolds. (The OEM ones are NLA).<br /><br />FYI... Merc style V-6 manifolds will bolt up to a 3.8L, but won't clear the front Selectrim jack.<br /><br />Wifey say hi to everybody!

Does the outdrive lift easy and smooth if you lift by hand? If not have your removed the drive and clean and greased the pivot pins on the back side. The two zert grease fitting do ok on the front side but the back side does not get much grease.<br /><br />My unit would sometimes not lift or only move 3 inches and stop until I removed the outdrive and cleaned all the old grease out then regreased. Since then about 10 years ago it will lift all the way in a count of 3 everytime. Down just takes a tap on the switch. I also use motor oil in the clutch.

like it's floating in water. I di dgrease the two back ones, where is the rear one. (It moved freely before I greased it too). I've tried tapping it etc too. I put 4 cycle in it, and when it goes it flies, when not just a click, or a slow drop then nothin'.

The wiring from the solenoids to the motor are usually the cause. Make sure you have healthy 10 gauge wire. Eliminate the plug at the motor, solder the wires together. The wire that feeds the solenoids could also be to blame. Need to be heavy gauge and not corroded.<br /><br />Start-up current when lifting the drive is very high. If connections are bad it won't move.

Re: OMC tilt troubles....still (Boomer, you there) ?????

hmmmm, you might have something here. For the first time (I removed the motor to have it looked at to be cleaned) I plugged it in, and it didn't start running hard right away. I slowly gathered up a bit and then nothin, then went. Couple of tries then it flew fast and furious. I think I may have it cleaned, and possibly re-wire to the solenoids then straight to the motor, no plug.

Um HELLO!!!!<br />I know you are very frustrated, but this is the first thing we told you to investigate. You said you did, but after this post you must have missed something.

Jh, be sure not to wash all the lube out of the end plates. In fact there will probably by a little felt pad at each end that you will want to reoil with some 30 wt. Do not immerse the armature in solvent. Clean it with brake cleaner, squirting from the commutator to the opposite end of the armature shaft. Make sure the grooves in the commutator are cleaned out and that the brushes are not worn below 1/2".<br /><br />You can do it!!! :cool:

Re: OMC tilt troubles....still (Boomer, you there) ?????

ummm, for the first time it ran this way un-installed. Every other time it ran fast and steady. I'm going to send the motor out and have it cleaned up and tested. If that doesn't do it, I'll re-do the wiring. As far as taking it apart myself, not I sir, no thanks. Thats for a pro, not me. Now if it would only stop raining........
