For future reference, the Fall is the best time to replace gear lube, pull drives, and check u-joints, etc. If there's any water in the gear case, you don't want it there in the winter as this will corrode components and run the risk of splitting the case when it freezes. Same applies to the u-joints. If the bellows sprung a leak, you want to minimize the length of time the input shaft and u-joints are in contact with water. The longer they are, the more expensive the repair.
At the very least, the gear oil should be checked every Fall by pulling the plug so you get a small sample of oil and can see if water comes out. If there's water in there, it should come out first. If water has been there for a while, you'll have creamy oil. Black burnt oil is an indication there's something wrong internally or it simply hasn't been replaced in a while. IMO, the drive should also be removed every Fall, check for water in the bellows, grease the u-joints if applicable, check the gimbal bearing, grease the spines. AND, don't forget to replace the anodes.
Not servicing sterndrives for 10 years is a big no no, and what you think you're saving by not doing anything every year will cost you way more in the long run.
Good luck, I hope you don't run into any problems, and keep us posted on how it goes.
