Protect Your Yamaha Outboard
Yamashield Rust & Corrosion Protection
The marine environment is one of the harshest on the planet, and that’s why protecting your Yamaha outboard is extremely important. For premium protection against rust and corrosion, we highly recommend Yamashield Rust & Corrosion Protectant. Yamashield replaces the T-9 formula that was designed by Boeing Aviation and is a combination of solvents, lubricants, and waxes. This means it has the ability to clean, lubricate, and protect your Yamaha outboard.
Yamashield attacks existing corrosion and adheres to metal exceptionally well for long-lasting lubrication. This all-in-one product can be used on all engine components, including wiring, belts, and electronics. It can also be applied to paint, plastic, rubber, fiberglass, or vinyl.
Application Tip: Use on entire engine surface areas beneath the cowling/engine cover.

Yamalube Marine Grease
Yamalube Marine Grease is specifically designed for the marine environment, is highly resistant to water and is critically important to protect your Yamaha outboard. It provides superior quality lubrication while adhering to all frictional surfaces, despite engine vibrations, to keep your engine’s moving parts working smoothly. We recommend using Yamalube Marine Grease on prop shafts as well.
Application Tip: Use for screws, bolts, shafts, and other hard contact surfaces to prevent seizing and locking.
Yamalube Fuel Additives Keep Your Fuel System Healthy
Yamalube Ring Free Plus
Yamalube’s Ring Free Plus formula provides superior deposit control for fuel injectors, carburetors, intake valves, intake ports, and combustion chambers. Deposits can either be the result of lower quality gasoline or just regular engine use. When left untreated they cause engine knocking, power loss, hesitation, shortened spark plug life, and piston ring sticking.
Ring Free Plus also helps to protect your fuel system against the corrosive effects of ethanol fuels. We recommend using it with Yamalube Fuel Stabilizer and Conditioner Plus. Use one ounce of Ring Free Plus to every 10 gallons of gas for continual treatment to protect your Yamaha outboard.
Yamalube Fuel Stabilizer and Conditioner Plus
Yamalube Fuel Stabilizer and Conditioner Plus is specifically formulated to protect fuel systems from the harmful effects of ethanol fuel, which include its corrosive effects on metals as well as the gum and varnish that result from fuel oxidation. The product also helps to prevent phase separation which is common with ethanol fuel. See PartsVu’s Knowledge Center for our article on the problems of ethanol gasoline in your fuel system. In addition, Yamaha Fuel Stabilizer and Conditioner Plus absorbs water in fuel line systems and extends spark plug life.
Typical usage requires one ounce of product for every three gallons of gas. We also suggest using this product before storing your boat away during the winter months, as it helps to prevent carburetor icing and gas line freeze. If you’re storing your boat for over two months, add one ounce of product per gallon of fuel. This will keep the fuel fresh for up to one year, so you don’t have to drain it for storage.
Yamalube Combustion Chamber Cleaner
Yamalube Combustion Chamber Cleaner removes horsepower-robbing carbon deposits that accumulate in an engine’s combustion chamber, pistons, cylinders, rings, and valves. In addition, it cleans out gum and varnish and helps free sticking rings. This is another great product to include in your seasonal maintenance routine. highly recommends it to extend the life of your engine and control carbon build-up.
Application Tip: Spray directly into the engine air intake. Use this product FIRST before any scheduled maintenance. We recommend changing spark plugs after using this spray. Follow the provided instructions on the can.
