Frozen manual tilt

[S10nook]

I have a 1994 mercury 25 hp outboard with manual tilt only. Presently the motor is stuck down and i am unable to tilt the engine up. Have tried penetrating oil, wd 40, greased all the fittings- no go. Engine has been in down position on trailer for about 1 1/2 years. Any suggestion?

Would a car scissor jack fit, with a block of wood on the transom?

The engine rotates on a bolt thru the mounting bracket. Loosen the nut.

Is it in reverse ?

Is it in reverse ?

Good point. Didn't think of that. Too obvious. Or, does it have a manual tilt lock button?

Yeah. You’d think it would be one or the other, causing the issue Jim ? Not much else to stop it.

iafter reinspecting the situation i believe the tolt tube is corroded preventing the motor from tilting. Came to this conclusion after removing the grease fittings which i paid soebody to grease to find out they were bone dry. Need suggestions now how to free up a corroded tilt tube.

No manual lock button. Engine is in neutral. Corroded tilt tube preventing engine from tilting. Took out grease fittings to find they were bond dry. Any suggestions to free up the tilt tube?

You will have to dissasemble the tube, clean it up and re-grease and put together. On my 35hp the shifter has to be in fwd to tilt it up, any other place it is locked down.

On my 9.5 Evinrude there is a lock to prevent the motor from coming out of the water. As mentioned above you can't tilt or move the motor up and down in gear, it has to be in neutral. Maybe apples and oranges as mine is Johnson and you have a Merc.

Maybe not in this case, but I have found many a motor that was sitting so long that the grease dried up and the metal corroded so bad it was almost welded together. Loosening the nut releases all the pressure and then it can be manually broken free.
