anyone have any experience with diagnosing steering arm play on alpha 1? the outdrive moves a considerable amount without the steering arm moving inside the transom. i'm not sure if it's the steering arm or the swivel shaft or the gimbal ring itself. what is the best method of gaining access to the bolts that hold the steering arm to the gimbal ring?

Ayuh,... Pull the Motor....

Once you get it apart, you'll know which parts need replacing...

What vintage is it,..??

There are two places where the play can occur. Either the steering arm is loose on the upper swivel shaft or (more likely) the upper gimbal ring clamping screws that clamp the gimbal ring to the square upper swivel shaft need to be tightened (easy fix). Retorque the clamping screws (two bolts at he top of the ring ) to 55 ft. lb. They have nuts on the back, so you will have to turn the outdrive side to side to get a wrench on them. See if that helps before you go any further. Should be an annual maintenance item. Good luck.

Tightening those bolts may lessen the play, but it isn't going to fix your problem. When that pin begins to loosen it damages the gimble ring that it runs thru. The pin is steel, the ring is aluminum.
There are three main things that cause that kind of wear on the gimble ring:
Driving the boat with the drive up past the trim limit height.
Having the transom assembly installed crooked.
And having a damaged, bent or broken skeg on the drive.
The proper repair is replacing the gimble ring which requires removing the engine, and drive, then the removal and disassembly of the transom assembly.
When the transom assy is installed on the boat, you cant get to the big nut that hold that pin in place.
This is where the boring a hole in the side (top) of the transom assembly comes in. It gives you access to that nut while the motor and transom are still installed.
Mercruiser sells a kit for this that has the template for getting the hole in the right spot, the instructions, and the plastic plug that you use to fill that big *** hole in your boat.
I agree with bond-o about that kit. I would never use one, personally. Not only are you weakening your transom assy, you are opening yourself up to a potential leak, and doing it that way doesn't allow you to inspect the assy to see if there may be other damage.
The kit is fairly cheap. The price of the gimble ring is gonna' break you heart.

I will partly agree. If tightening the bolts does not remove ALL of the play, the square opening on the gimbal ring has probably worn to the point where it needs to be rebuilt or replaced. If on the other hand if you can tighten the gimbal ring on the shaft (as was the case with mine) as long as you keep it tight and retorque the screws as a regular maintenance item you should be OK.

If your ring is worn, these guys can rebuild it for a lot less than the cost of a new one http://www.jrmarine.com/ :)

Wow, your bolts come loose, Terry? They shouldn't, unless they have been stretched. You might want to replace them and the nuts as well. But properly torqued bolts wont loosen up, that's why tightening those rarely works, unless, of course, they weren't installed correctly from the factory.

Yes they did, (well the ring became loose anyway, had about 2 inches of play) in fact I pulled the ring and sent it to JR for a rebuild, and they said it was OK so sent it back. Reinstalled and torqued properly and it has been fine for two seasons now. I do retorque it every spring now. I suspect that rather than the bolts, the stress can deform the aluminum ring over time, and it doesn't seem like it would take much to cause it to need to be retightened (Merc says to do it every year). A lesson learned the hard way.:rolleyes:

Re: alpha gen 1 steering arm play

:)The gimbal ring has a slot cut down about 2 inches to allow you to tighten the 2 bolts. I cut this slot 1 more inch to let it tighten the square shaft a little more. Than I weld the slot to original position. Don't try this if you are not an advanced welder. Most of my crazy repairs work, but I've had my share of failures as well. I only do this on drives that are worn out.:)
