Don’t Let that Fuel System Corrode in the Offseason

You’ve done everything right so far. When it came time to winterize your boat, you followed every solid piece of advice, from flushing the outboard engine with fresh water to disconnecting the fuel hose and changing the gear oil. Unfortunately, there’s one minor detail you may have overlooked, and it’s a doozie. It’s just as important to care for your engine and its components during the offseason as it is during the height of summer.

While your boat is still being used regularly, you’re always diligent about replenishing the supply of bulk oil, so don’t skimp on the essentials during winter. You’ll need to implement a fuel additive – a stabilizer specifically – to ensure that the fuel system doesn’t corrode from disuse. During the summer, most of the varnish and other assorted buildup in the fuel system is flushed out as the engine is in regular use.

These additives keep the system well lubricated so that rust and corrosion don’t build up on the bare metal parts in the fuel system. Since it’s nearly impossible as well as unadvisable to drain all of the water out of your fuel system, additives keep excess water at bay, preventing varnish and sludge from depositing inside the injectors, carburetors and other vital parts of the engine.
