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??

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.
