Sounds like the engine is going to be your biggest headache. If the fuel wasn’t treated, or perhaps after that long, even if it was, you may need to go over the entire fuel system. You’ll have to get rid of the old fuel and clean out the tank. Just putting new fuel in there isn’t going to be an answer. The sludge won’t break down well and if the system should suck up some of it at an inopportune time, it could be disastrous! Rebuild or replace the fuel pump and carburetor and clean out the fuel lines and replace the filter(s). Spray carburetor cleaning fluid works well.
Go over the engine cooling system. Clean out the heat exchanger, if you have one and replace the water pump(s) impeller(s). On some engines, it’s possible to pump some lube into the pump shaft(s). Check all of the rubber and replace hoses as required. You may want to test or just replace the thermostat.
Change the oil and filter and replace the drive belts, plugs, wires, points, condenser, cap and rotor, and you should be all set with the engine. Check/change the fluid in the reverse gear and R&R the prop shaft packing gland. Lube the shift and throttle linkages.
Hook up a “Fake Lake” and run it up to check all of the systems and alternator output before you go in the water. You''ll want to re-change the oil and filter after this run up. You may need to replace the batteries too.
I think that you may want to uncouple the prop shaft from the reverse gear until the boat sits in the water for a while. Even fiberglass boats will “twist” after sitting ashore for a while and the shaft may need to be realigned to the engine after she settles back in her natural environment.
Of course there’s most likely going to be a need to replace or rebuild most if not all of the switches and breakers in the power distribution panel and lighting. Painting all electrical connections with petroleum jelly will help maintain good mechanical contact and keep corrosion in check. Bilge pumps should be tested and rubber diaphragms replaced as required. Potable water systems need to be cleaned and flushed.
Before you look at all of this work as perhaps a bit overbearing, just remember how much you’ll be learning about your boat. For the modern sailor, I don’t think there could be a much more unnerving situation then crawling out of the bunk at 2:30 AM to answer natures call and stepping into sea water up to your knees! When the crap hits the fan as it does, at the worst possible time, you’ll have a far better idea of what to do to fix It quickly and with less guess work.
