Aloha folks,

I noticed no responses to your dilimma and am somewhat surprised. Although I do not currently have a Mariner, I am very interested in these situations as I am about to acquire one myself. I'm always interested in unique situations like yours for obvious reasons.
May I suggest you post a like message on Cruisers Forum...perhaps you might be more likely to obtain a response, not to mention, other related info regarding port availabilities and assistance in the Panama area.
Since this is already the 28th, you may be well along with a solve of your situation,,,,but it would be nice to hear the results. Wish I could be of more assistance.

Incidentially, been thru the canal a few times...on much larger vessels...I fully understand how you might feel in that geographical situation with such a unique, if not diffficult problem.

[> Cutlass bearing -- Doug Wilson, - Monday - 01/28/13 - 8:43pm

The size is right, order online and the bearing should be about $60.00- $70.00.
Pull the prop, get the flanges apart, some brake fluid may help loosen the nuts, a propane torch may be necessary too. You may have to loosen the packing gland as well, and while the shaft is out, plan on replacing the hose on the shaft tube, I think it is 2 1/8 " ID. Mine was the same as the exhaust, and I had some spare on board. Also replace the packing, I think 1/4". Plan on new bolts and nuts for the flanges, make sure they fit exactly.
With the rudder hard over, the shaft will slide out, but may not come out easily.
The bearing has at least one set screw holding it in place, just sand off bottom paint and gelcoat to find their location.
You will have to use a hacksaw blade to saw through the brass on the bearing, once the integrity of the bearing is broken, it should come out.
Clean everything, flanges, shaft, packing gland, shaft tube.
I set the new bearing with 5200, and the set screws, but the more I use 5200, the less I like it.
You may need some feeler gauges and some shim stock to align the flanges, I also had the engine aligned after a couple of days in the water.
Sounds like a lot of work, but should not take more than a day or two.
It can be done, and you can do it.
