I bought a 1994 Sea Ray SC2100 this spring. I had it winterized this
fall and the Marina told me the lower unit oil was milky white,
indicating water was leaked in. They filled the unit with new oil, ran
it for a few minutes and drained it again with the same results. They
then performed a pressure and vacuum test. The pressure test passed,
but the vacuum test failed. It would not hold a vacuum. I have never
had a boat fail either test or have water leak. Before moving forward
with a repair, I'd like to understand what could be the problem and the
estimated cost associated. Can someone offer me some advice?

Sue, it sounds like you have a bad seal in the lower unit, and they do
wear out, it must be repaired. If you do not get it repaired be
prepared to pony up for a new lower unit next season. Put simply, the
water getting into the lower unit will corrode the working parts within
the lower unit, additionally, water is a poor lubricant, as it
displaces the gear lube the moving parts will wear out quickly. The
repair bill right now shouldn't be that bad (remember, it's a boat,
nothing is cheap when it comes to repairing one). So get the repair
done now, so you can enjoy the boat next season.
