omc tilt motor

[kenny40391]

ok as stated in the other thread i started about my omc outdrive. i got it tore apart and ordered a impeller kit for it but im needing to order a tilt motor and i dont have one to compare it to cause mine was gone when i got it. everyone says its a stringer . ( i have pics of it under my other post about what outdrive). my holes are threaded and dont see anyway to put a nut on the inside i have found 2 motors and was wondering what i needed thanks for the help here are ebay links to both style motors http://cgi.ebay.com/ebaymotors/Tilt...at_Parts_Accessories_Gear&hash=item3f0accf398 http://cgi.ebay.com/ebaymotors/NEW-...at_Parts_Accessories_Gear&hash=item5d2f33643e thanks again for the help

Re: omc tilt motor

I have a 77 OMC electric shift and I had to replace the tilt motor a couple of years ago, judging from the pics in your other post you have an electric shift too. in that case you would use the first link to ebay. My motor worked fine but it sheared the 2 flanges on that shaft and they broke off in the hammer blow coupling. I hope that is not what happened for you. Good luck

Re: omc tilt motor

i cant figure out how the fist one would mount. the holes going into the mount is threaded and i dont see how the studs sticking out of the motor wouls work without putting a nut on the back side. but i hope there isnt nothing wrong other than the motor missing everything else seems fine so far. i was thinking it might be the second motor where it takes 2 bolts holding it on but im clueless. thanks for the fast reply

Re: omc tilt motor

I'm receiving my tilt motor 2 morrow, I had the same problem this season.. I bought mine here on Iboats though, some one instructed me to stick with the Sierra Tilt Motor, and not the "ebay ones" for this omc boat part... it is a lil more Expensive here.... But, I had the same problem" No numbers to Identify it" Mine is an 1986 omc 3.0l and the new Sierra tilt motor, replaces to kinds of Presto-lite motor's for my 1986, this looks like the late 70's early to mid 80's tilt motor.. I had to look at them carefully because there were no numbers and no one here has confirmed my old one to the new one, I assume I picked the right one based on the wiring, and how it looked over all... I guess I will know this week.. I'm knew to this.... Hope this helps a lil.
p.s Mine bolts directly to the Lower right side of the transom in the boat under the rear engine mount if ur facing the motor in the boat, with 2 threaded 13 or 14mm bolts. My tilt motor's short slotted shaft goes through the transom and into the wormscrew/gearcase housing on the outside of the boat On my lower unit.....

Re: omc tilt motor

that sounds like the way mine works also. but im not a inboard outboard guy its my first. so i am clueless

Re: omc tilt motor

It's the 2nd ebay link. There should be 2 threaded holes to run bolts into through the flange. The tilt motor mounts on the lower port side of the intermediate housing (the housing that attaches directly to the motor). You'll probably want to take the cap off the end of the worm gear on the outside of the boat so you can inspect the shaft & hammer-blow coupler. Often the tabs on either side of the slot in the end of the worm gear shaft will shear off and your tilt won't work - either the motor will bind & just click or it'll spin & nothing will happen. There's a good many threads on here about servicing the Stringer tilt mechanism including instructions on how to get that worm gear, shaft & hammer-blow coupler out. It's not hard.

Make sure the clutch housing is water-free & well lubed (I'd recommend stuffing it full of marine grease as opposed to the recommended 30w gear oil - keeps water out better - they're notorious for leaking). You'll have to take the clutch pack out to get the worm gear & shaft out anyhow.

Re: omc tilt motor

Just dealt with mine this year, but I was able to have the tilt motor rebuilt. I have a '72 Electric Shift and the second link wouldn't work - definitely the first link.

The way it assembles is running the bolt shaft all the way through the motor into the housing - it's a PAAAIIINNNNN to put on. The bolts that attach the motor to the housing actually hold the motor together (those nuts on the end come off, and it attaches to the housing right there). I used some electricians tape to hold the motor together while I put it on ... never cussed in the process, but got REALLY close

Poor images, but it's all I have - here's the assembly:


And here's a rough side view of how it attaches to the housing:


OEM part number was #0382138 (Prestolite motors, I believe), and I think they were the same '63-'77. So, check your model year if you're past '77.

Follow superbenks advice too and check all the "innards" out while you've got it apart. It's a booger to get back into later.

Re: omc tilt motor

Ah, ok. Electrics must be significantly different with the tilt motor than hydro-mech/mech. Sorry for the mis-information.

Re: omc tilt motor

The first ebay listing is the one you need for your electric shift. What you call studs, on the motor, are not studs but thru bolts, They just put the nuts on it to keep the motor from falling to pieces. The thru bolts both hold the motor to the intermediate housing and hold the motor together. There ought to be a heavy gasket on the face of that motor. See black face in the picture of my motor. You may want to make one and glue it on.

Also be sure that that hammer blow coupling and drive shaft are in place or a motor will do you no good.

Re: omc tilt motor

Kind of on the same topic...

Can you replace the 3 wire TRIM motor with the 2 wire trim motor? I understand the 3rd wire (black) is just a ground.

But will the motor it's self fit and will it have enough power?

Reason I ask. I had some work done on mine. I am really unhappy with his work. He use a Through bolt type motor for the TILT. (it has threaded holes for the flange type) but I am still missing a TRIM motor.

I figure I can buy a Good tilt motor (with the flanges) and replace the non flanged one with it... then use the Used non flanged motor for my trim.... (minus the 3rd wire for a ground... )


Or would it be better to just leave the non flanged one as the Tilt motor.. and buy the 3 wire Trim motor? it is about $100 more... but if the 2 wire will fail... then it is not worth saving that much..

Thanks

You can't interchange the motor styles. It has nothing to do with the wires, it is the way it mounts to your intermediate housing.

Re: omc tilt motor

thanks guys have everything on order except the hammer coupler that i didnt know i needed. but will order it asap the new tilt shaft it back ordered but is supossed to ship out in 10 days

 

[superbenk]

Re: omc tilt motor

Did you actually take it all apart or just order a buch of stuff? You might not actually need that stuff if what you have is fine.

 

[kenny40391]

Re: omc tilt motor

motor and hammer coupler was completely missing . the worm gear shaft had the end broke off of it. i ordered the motor and shaft before i knew there was a hammer coupler that went in there .

 

[southkogs]

Re: omc tilt motor

Well at least you didn't get it all put together only to find out you had to take it all apart again ... it's a real rib buster to crawl back and work on mine. While you're at it - and have everything taken apart - you might go ahead and put new solenoids on it. They're not that expensive and you can grab them at the local auto parts store.

 

[kenny40391]

Re: omc tilt motor

done replaced the solenoids on it mine is on a 28' pontoon so its not been that bad to work on yet. i hope after i find the hammer blow coupler if i can find one i will be able to put it on the water .

Re: omc tilt motor

I had seen a few hammer couplings on ebay when I was looking before, but you have to type in OMC and then just sort through stuff. I went back and found a couple options here, here and here. If you want to check a couple of salvage places. There's one that I've done pretty well with so far in Georgia - these guys.
