OMC out drive stuck down.

Re: OMC out drive stuck down.

Game plan for now, pack the clutch box with grease, and dry gasket. Remove snap ring on round tilt quadrant gear. Loosen 4 bolts to clutch box. Push clutch (right to left) out of housing until round tilt quad gear falls. Drop O/D to down, re-install tilt gear, snap ring, and tighten clutch box...until I can get a motor.....At least this way I can still cruise!!!<br /><br />Is there something worse than a boat that runs good, and can't be used!

Have you tried to clean up your tilt motor?<br /><br />jh, be sure to read my post above.

Boomer... my model is an '82. The kit came with and the diagram shows two outer seals, back to back (or face to face depends how ya look at it).<br /><br />I am almost sure that it's the same through 85.

Yeah but, yeah but I just stopped by my OMC guru's today (because of this thread) and he whipped out the latest greatest reseal kit. It had a single but wider double lip seal in it. He said it was the better deal but still would probably not stop the dang thing from leaking.<br /><br />He said to install a 1/8" ss pipe plug, in the bottom of the gear box (which I had done long ago), cut a channel down the face of the trim motor face gasket, install a big ole fat oring on the motor shaft and drill a hole in the bottom of the tilt motor housing (which I had already done, long ago. see pic above)<br />All that will keep goo from entering the tilt motor. What little might get by will just drain down the face of the pump or out of the weep hole as picture above.<br /><br />Then every couple of trips just pull the drain plug, let it drain and refill. He also said whatever you do, do not lighten the clutchpack tension.<br /><br />Ya listening jh?? I hope ya haven't gone to bed yet!

Re: OMC out drive stuck down.

I haven't done anything to the clutch pack. It came out a single unit and remains a single unit. No winding, no nothing. I also am not the one trying to kick it up in reverse. I didn't think that would work, if I cant lift it up with that much leverage, it ain't budging by water pressure going by it. The motor it self was water logged. It was a prestolite evd4002 so someone's been here before me. Thought about having it rebuilt, but not having luck around here. Suggestions for that one? and yes, I'm going to bed.........

Re: OMC out drive stuck down.

'scuse me jh, it was boatist that left the shims out. Post a pic of the components of your tilt motor and I'll tell you if and what you can do. Nitey nite

Re: OMC out drive stuck down.

Kagee/Marinemech1<br />I will have to disagree with you both at least for the 1980 model I have.<br />Yes there is a special tool to attach to the clutch and you use a torque wrench to messure for 150-185 foot pounds of torque.<br />From the 1980 OMC factory manual page 6-9.<br />"If the torque is too high, remove shims as required. If the torque is too low, add shimms as required."<br /><br />Also on my model there is no way for water to enter from the motor shaft unless the casting has a hole eaten in it or the water is so high in the bildge the motor is flooded inside the boat.<br /><br />Maybe they made a change on other models. If I ever need to reseal it again I will remove at least one more shim as I want the drive to kick up if I hit something at sea. I would rather the motor kick up then bust off the lower unit off or rip the transom off.

Re: OMC out drive stuck down.

Funny story, btw, good morning, I was in the boat for the first time a few weeks ago, and forgot to close an engine seacock under the head. My daughter and I are toting around the charles river in Boston, I look back and see water around my battery. I hit the bilge pump and turn around. (add to this my son calls to tell me he forgot his baseball equipment for school, so I yank the boat out, drive 45 minutes home to get the equip etc etc etc). I am thinking now that the water level "could" have reached the tilt motor on that "special" day. It is mounted right about even with the port rear engine mount. On the other hand, I think my starter would have been in the drink then too. Who knows, but none the less, the design is rough at best, and anything to keep the evil that we enjoy (water) out of the boat and it's "affordable" parts would be a welcome addition to our holes in the water. <br /><br />As far as tourque goes on the clutch, There was something I read in my manual that said to turn it 4 times (not sure which way) to wind it. I can look it up if someone needs it. Mine is a 1981 GM OMC 400 2.5 litre.<br /><br />I realize I am doing alot at the ramp to be able to go out, buts whats a poor boy to do?<br />-Jeff

Re: OMC out drive stuck down.

BTW, no problem boomyal. <br /><br />I loked in my book, (clymers) 4 revolutions minimum to 150-185 ft-lbs. Then adjust as needed. <br /><br />What puzzles me is this.<br /><br />My current situation is: Tilt motor is out. Clutch is in and I have not wound it. Quad gear is installed, as is round gear on end of clutch assy. The drive stays up / down. Why? (I'm not a huge electrical person), but could the hammer blow have been responsible all this time? What is holding the weight of all this?<br /><br />If I reach under the engine with the innerds of the old tilt motor, I can start to spin the assy by hand, but it springs right back.

if I'm understanding you correctly, (quote: The drive stays up / down)that is a good thing! It means the clutch is working. The worm gear is what moves it up or down depending on the tilt motor's direction.<br /><br />It was OMC's intent that the sterndrive remain down, except for trailering. The fastest way to kill your ball gears is to operate the engine with the drive in ANY position other than all the way DOWN!

Re: OMC out drive stuck down.

Boomer... The seal mod must be a new thing... was it from Bombardier??

Re: OMC out drive stuck down.

Right, I just want to know whats holding it up. Did you see how I lower and raise it? I remove the clutch and snap ring so the round gear falls off. Lower the drive, reintstall the clutch, round gear and snap ring and off I go. Which I might just do in a few minutes. Lake Cocituate is wide open, and a really windy cool day of 48 degreees! Great day for the boat!!!!!!!!!!!!!!!

Yes

Re: OMC out drive stuck down.

I think I just found the problem with the whole damn thing. Someone used the wrong motor! I noticed a few places state that the EVD4002 I pulled out of the boat is for all 1979-1985 sterndrives except 2.5 & 3.0, I have the 2.5 gm 1981 OMC.

Re: OMC out drive stuck down.

Damn it's cold on the water! Now that my fingers thawed out, the only issue I had with doing things this way was I needed to have my step son stand on the trailer half way between the truck and bow, to lift the back of the boat up enough to keep the skeg from scrapning on the ground. This is nuts, I need a tilt motor............

Oh oh! Maybe no $60 tilt motors for you. What is supposed to be the difference. Seems that if it bolted up it would work??

Re: OMC out drive stuck down.

Probably the way it seals, or lack thereof to the intermediate housing? Maybe thats why it filled with water. Who knows, all I know is I wish it worked!

Re: OMC out drive stuck down.

JH19<br />What holds it up is just the worm gear. Even without the motor attached almost imposible to cause the motor worm gear shaft to turn. I can not see how you get the snap ring on with the drive down.

Re: OMC out drive stuck down.

Turn the steering wheel to the left all the way,(drive turns out left) and use a pair of off set snap ring pliers from the right side underneath. It's actually easy to get to this way. The hard part is holding the clutch assy halfway out so the round gear will fit between the outdrive and the back of the clutch housing, and fitting the round gear onto the tilt gear. You have to pull out the clutch and turn it so it all lines up. It all makes having the motor seem rediculous....: )
