my best suggestion is to use a fuel stabilizer treatment in the tank each time you add fuel, that way, if you get distracted for a couple of months, you won't come back to skunk gas, btw, keep the tank close to empty when storing, the condensation thing is total bs, I'd rather have 5 gals of old gas that I can dilute with 20 gals of fresh, than have 25 gals of old gas to deal with. Try to find ethanol free if you can, it should be getting easier since the subsidy and tariff was removed last August. If you don't already have a spin off 10 micron filter, you need one. If you know you are going to put the boat up for a while, hook up a small outboard tank to the engine, run a mix of fresh, storage treated, ethanol free fuel, mixed with 50-1 two stroke oil. Drain the vst tank if its fuel injected, pump up the primer bulb, start and run the engine till it starts to smoke a little(it takes a while), that way you know treated fuel got to everything, the added two stroke oil will keep the fuel pump check valves from sticking. Store the engine trimmed down, check the gear lube for water and check the engine oil for water or high levels with a gas smell. Now's the time to do repairs, not June!
