Thanks, Bill. I'm much the same -- prefer not to get dirty (especially when I could be out on the boat), but willing and able when I have to. I also refuse to let anyone touch my brakes...I guess you can translate that into a trust issue, but you can see what happened on the rare occasion when I trusted someone to tell me the ski line was clear. I also hate to pay for something that ends up being so easy as you describe.
I was actually thinking of a pictorial diary, though I was thinking more in terms of making sure I could put it all back together. So there's a high probability I can put something together for the group, maybe with references to the Seloc manual to help fill in the blanks Ethan described so well. For the record, I have a late-1967 drive with a 5-bolt cap that is actually listed as a 1968 on the BRP site (HU-16C).
After talking more with Don, I think my biggest question at the moment is if I can get the lower gearcase removed without removing the upper. Has anyone done this? The wires seem loose enough at top (obviously I can't tell at bottom) that I was thinking I might be able to attach a lead wire to pull down through the upper unit so I'd have a means to feed the wires back through after repair. It seem if I support the lower gearcase with a floor jack (and/or some straps) I could slowly lower it as I progress. Obviously the job will be much easier if I don't have to pull the whole unit so I'm really hoping this will work. The wires do look a little "dry rot" so I plan to dig up some of the past notes on replacement wires -- more use for those 150+ e-mails I've saved! Speaking of which, I had a thought on how to categorize all those e-mails -- perhaps follow the same grouping as the BRP website? Maybe that can be my next project.

Subject: [OMC-Boats] Lower Unit Rebuild
Hey Andy,
I had a classic car one time that needed a valve job so I took it to a car club mechanic byddy. He charged over $800 to do it. I visited his shop one afternoon and discovered all he did was to pull the heads and send them to someone else to the valve work. Well heck, buddy or no buddy, I could have saved $600-700 by doing that work myself, so the next two valve jobs I did the same way saving a bunch of money.
I'll admit up front to having a certain disdain for greasy grungy mechanical work and would really prefer someone else to do it....but not enough to shell out hundreds or thousands when I KNOW I can do the work myself. So....with a deep breath and gritted teeth.... I get my hands dirty.
I found on my last (and first) boat that marine work is terribly expensive to farm out soooooo.......this time, after obtaining the applicable service manual and the oh-so indispensible parts manual and studying both, I resealed my sterndrive myself. It wasn't difficult and I easily saved myself probably $1200-1400 or more in the process.
I was going to check the lower unit as well but since there wasn't any obvious reason to do so, I decided not to venture into it except for the seal on the outer cap behind the prop. It was a good experience as now I "know" first hand what condition the drive is in should anything come up down the line. Those of us that choose to do the work ourselves could sure benefit from hearing your experiences with it.
Maybe you can chronicalizer you venture in diary form with pics??

Wow, guys, I can't even begin to thank you for all the help that's come in. Short of flying up here and doing it himself, Don sent me just about everything he could offline, right down to a tools and parts list. I tried bidding on the clutch spring Joe pointed out on eBay and after the price jumped past $45 (hope I wasn't bidding against any of you!), I decided I needed to confirm the problem before randomly buying parts. I made a note of the Tacoma parts source Scott sent and expect I'll be checking prices and inventory there before I'm done.
Unfortunately it looks as though my season is not only over, but I have no choice but to tackle this myself. I called the mechanic who usually does my work when I don't have time and he said the part was $422 and labor would run $600 - $1000. By the time you add in seals, lube, provision, etc. it'll probably push the $2k Don was quoted. So my plan is to start by spending a lot of time studying everything I can and collecting tools, then I'll try to get it apart and confirm the problem is the spring tab and not the coil as Lee thinks before tracking down other parts. The boat is now safely in my garage at the lake and once I can get the tools gathered there, its actually a much better place to work than home...at least until it gets cold. If I can't wrap things up before winter, I'll have to try getting the lower gearcase removed and into my basement at home for a winter project. Also on that to do list will be a custom designed ski harness that can't reach the drive! Thanks again, all!

Andy,
There's another easy way to check electrical operation of the coil. With the ignition key on, but motor not running, shift from neutral to forward and then repeat for reverse.
You should be able to detect similar current flow for both directions. You can usually observe this a couple of different ways: A) Close obeservation of the ammeter, and I do mean very close. B) Close observation of a light bulb or volt meter, as there should be a barely perceptable voltage drop when the coil engages (this is also a function of state of battery charge, ie a smaller weaker battery, will have a larger voltage drop. I'm guessing (educated) here, but I've never heard of a clutch coil electrical failure due t0 mechanical interference/stoppage. Clutch sping yes, coil no. The "tab" is part of the spring.
Without access to the special tools, you mention, personally I wouldn't attempt to do the lower unit repairs in the wild. My educated guess is you'll be able to get all the parts back in Detroit. So if it were mine, I'd call it a season and do the repairs with the proper tools and service manuals handy vs on the edge of a lake or back of the trailer. Sorry my news isn't happier.

Thanks, Lee. I just realized my earlier reply to Don went only to him, but I was able to walk my wife through measuring the coil over the phone this morning. Unfortunately I only have a cheap multimeter with 10k or 1k scales so both readings of "0" could effectively have been "0" else 4.5 - 6.5 ohms on that scale. If I can get the parts this week, I feel fairly confident I can do the repairs next weekend. I think my two biggest concerns are:
1) Do I need any special tools to get it apart and put it back together?
2) Getting parts (especially not know what part(s) failed)
I lost all of my special tools (gear/bearing pullers, clip spreaders, etc.) with my Dad's toolbox (long story so let's just say I hope none of you ever have to experience the horrors of Alzeheimer's) and I only have a limited tool set at the lake. It was late by the time we got back in so I ended up leaving my whole rig there (including manuals - d'oh!); if you think its the spring tab that broke and I can find one for a reasonable price, I just assume get one now (I have much better luck finding parts near Detroit vs. the small town in Ontario where I boat). Its not just the repair costs, but if I have to depend on a shop, my season will most likely be over and August is the best month around here. Is this spring tab part of the spring itself, i.e. I need to find a spring pack? While I'm waiting for my wife to bring my manuals back, I'll try pulling the part #s from the BRP site in hopes of tracking parts down after work today (Michigan Marine Gear usually has this kind of stuff in stock) . What about gaskets, springs, circlips, etc. -- anything else you think I'll need?

First check the forward and reverse coils (one at a time with an
ohmeter, out of circuit.)
A good coil will read between 4.5 and 6.5 ohms.
Most likely the electrical coil is okay but the spring tab has broken
off.
I wouldn't recommend fuse-protecting the coils, but you can calculate
the current flow in amps using Ohm's law. I generally see 2 to 3 amps
current draw on my digital ohmeter, when shifting with the motor not
running and battery at approximately 12.3 volts.
