I have a 1972 omc 120 hp, had to lift outdrive up after it would not go up with the tilt switch and now it's stuck there. I try and tilt it back down and all I hear is the tilt motor winding out I think, any suggestions? |

So you have a stringer out drive that won't tilt up, or it tilts up very slowly, or you need to help it up physically. Maybe it doesn't move at all.
Here is a step bye step guide to fixing it. A manual would be very helpful.
1- A fully charged battery is imperative.
2- Disconnect the battery and clean the battery posts. Are the cables good?
3- With the battery disconnected, clean all the connections on the port side, solenoids. Don't forget the grounds.
4- Clean connections to tilt motor. Two wires.
5- Connect the battery.
6- On the out drive port side, there is a clutch housing. Four screws hold on
cover. Pull that cover. May be full of water. They all leak.
Two things you can do at this time.
A- Clean out the housing with clutch installed.
B- Remove the clutch and rebuild the housing. New seals.
If you chose A, Spray the clutch with brake cleaner. Make sure it's as clean as you can get it. You might have to spray it a few times. Blow it dry. Spray the the clutch with penetrating oil. Pack the housing with grease, and install cover. Don't over tighten the screws, can bind the clutch.
If you chose B, remove all the components of the gear housing. Soak everything in Acetone overnight. Rebuild housing, new seals. Blow dry the parts, soak them all in motor oil for a hour or two. Install parts. Pack the housing with grease. I know it calls for 30 weight motor oil. Trust me pack it with grease. Install cover.
7- Gently pry off the rubber bumpers. Don't mix them up, pump grease in the zerks. Install bumpers.
At this point the drive should move up and down easy. If it doesn't, you need to pull the tilt motor. Test motor and replace or rebuild. Make sure the hammer blow coupler is good or replace. Don't forget the gasket, on the tilt motor. .
Good luck!

^^ pic of one,
it resides between the end of the motor and the horizontal tilt shaft
It's function is to allow the motor to develop a bit of momentum before it has to pick up full load |

$50 for hammer blow coupler, but the new brass one beats the heck out of the broken aluminum one. |

I think each shell is $50, and the spring is additional, so about $110 or so |
