Replacing gimble bearing, Alpha Gen 2

Re: Replacing gimble bearing, Alpha Gen 2

Finally got time to mess with the boat again...
Got the water (this went on real easy with a little silicone grease) and lube hoses on at the transom ends. Attached the transom end of the drive boot and got the new gible bearing snugly home.

I have the shift cable in more bits than I probably should have and am yet to attach either end of that as it isn't mentioned in the instructions I have. Will go read up on it but if anyone has thoughts to share I'd be grateful.

The bearing driver engine alinger bar combo worked great on the bearing tho I'm not sure when/how to align the engine/drive or how to tell if it is needed.
It also came with a aluminum ring (pic above) that I'm yet to find a use for....

I seem to have learned way more about the drive than I really wanted to and still not enough to mess with it without help.

If anyone has a decent pic of how the hoses, wires etc feed thru/round the gimble ring that would be really handy too.

Much thanks

Nick..

Back again....

Bellows all on.
After I gave up my buddy Mike but the prop shaft bellows in in under 5min....
Will have to try him on a bottle ship next I gues.

Last problem.
The prob runout is about .016
I've read online 0.010 is acceptable and the merc manual suggests even less.
If I run as is I'm guessing increase wear on the bearing and maybe a lil virbation.
My question is will this trash the lower in a few hrs, weeks, years?
Thanks.

Nick.

Minutes, plus tear up other things from the vibration.

Is s possible to straighten a prop shaft 0.007 on the drive?
To have it replaced at the local boat yard is simply more than I have to spend and seemingly a good bit more than replacing the entire lower with an SEI unit.

Re: Replacing gimble bearing, Alpha Gen 2

It has to come out to straighten, but it also takes a machine shop that knows what they are doing to do it correctly. If you found someone that could dismantle the lower unit, take the shaft to the machine shop, and rebuild the drive, you could do it fairly inexpensive. But this person would have to know what they are doing because the rebuild is more involved than tearing down. Otherwise, go with the SEI outdrive.

I found trim sensors on eBay for about $65. Check out Jim's Marine on eBay, great guy, fast shipping, great prices. I have done quite a bit of business with him, and I will go to him before anyone else. BTW, the trim DOES work without the sensor and sender. I am going to replace mine also, just because I don't want to have one of those boats that when you use it, you have to do a certain thing for this to work, tap the engine there to start, etc.

I have a set of trim sensors in great condition. (75 hours and about 5 years old) I changed them out last year before finding out grease had found its way on the contacts causing erratic readings. E-mail if interested. beech30144@yahoo.com Thx Kevin

Anyone have experience with this?

Same cost as a new SEI lower but an interesting concept.
