I hope it's going well, though fixing steering is a project that's more fun
in the summer (unless you have a heated garage), as most of it has to be
done in the boat.

I'm doing some serious repairs this winter too, as shown here:

Does anybody know the most common sources for leaks in the upper gearcase?
I've been seeing a little water in the oil for a few years now, but it got
a lot worse this year - no clean oil drained at the end of the season, and
every internal surface was coated with a white frothy mixture of lube and
water. The gears and bearings all look and feel fine, but I figured it was
time to fix it before anything is damaged. It hasn't been apart since I did
the ball gears in spring '05, and I don't think I replaced any seals back
then, so I guess I've gotten a decent life out of the last seal job.

I've got a full seal kit on order, but some of them look pretty difficult
to get at. My best guesses are the top swivel o-ring (which looks pretty
worn and will be trivial to change), the o-ring behind the steering gear
(which everyone says is often a source of leaks), the shaft seal behind the
ball gear (I've had it off before, though it took a huge press), or the
shaft seal going to the bottom (which looks horrible to get at - I've never
removed that assembly). I've also heard that leakage from the water pump
can cause upper gearcase leakage, so I'm going to try to do a better job
sealing it this time.

Any other suggestions?
