KILLS RUST AND CORROSION WORLD'S GREATEST LUBRICANT, PENETRANT & ANTI-SEIZE SAFE ON ELECTRONICS CorrosionX® is the most advanced and effective corrosion prevention compound, lubricant and penetrant in the world! Although it may look similar to other oil-based anti-corrosion sprays, CorrosionX...
Corrosion X is your friend. I spray the motor everywhere, keeping it off belts and off air filter. I even spray the exhaust, start the boat up and burn the oil off leaving a film maybe. The motor will stay oily. You can’t run dirt roads because sand will stick. When I get back I normally just rinse the engine with water wash the exhaust with Dawn and when dry the salt shows white on exhaust. I spray it down and it cleans it up. I only spray the engine as needed. If I ran dirt roads I use T-9 Boeshield which dries a little. I am trying this on a new engine. I still spray Corrosion X on cables and such. Your engine will get a honey color after a while but I would rather that than weathered.
Running GTO LS motor here in Eastpoint, Fl. No real issues...rinse it off occasionally. Headers and exhaust tend to have surface rust. Spray it down with Sta Bil Rust stopper. Use a lot of plastic UV protector on plastic covers.
