Summary

Regular maintenance protects your Yamaha outboard from the harsh marine environment. From corrosion inhibitors and marine‐grade greases to fuel additives, external cleaners, and heavy‐duty covers, the right products will restore lost power, guard against wear, and extend engine life.

1. Corrosion & Rust Defense with Yamashield

Yamashield Rust & Corrosion Protectant cleans, lubricates, and shields all metal surfaces under the cowling. Formulated from Boeing’s T-9 legacy, it battles existing rust and bonds to wiring, belts, electronics, plastics, rubber, fiberglass, and painted surfaces for long-lasting protection.

Application Tip: Spray generously on all exposed engine parts beneath the engine cover.

2. Marine-Grade Lubrication

Yamalube Marine Grease clings to friction points—even under vibration and water exposure. Ideal for prop shafts, tilt pivots, cable linkages, and fasteners, it prevents seizing and ensures smooth operation.

Application Tip: Apply to bolts, shafts, and any metal-to-metal contact surfaces.

3. Fuel System Health

Maintain peak engine performance and protect against ethanol damage with Yamalube fuel additives:

• Ring Free Plus: Controls deposits in injectors, carburetors, valves, and chambers. Use 1 oz per 10 gal of fuel.
• Fuel Stabilizer & Conditioner Plus: Prevents phase separation, gum, varnish, and water buildup. Use 1 oz per 3 gal (storage: 1 oz per 1 gal for up to 1 year).
• Combustion Chamber Cleaner: Dissolves carbon and varnish deposits—use before routine maintenance and replace spark plugs afterward.

4. External Cleaning & Detailing

Keep exteriors ship-shape:

• External Engine Cleaner: Powerful degreaser safe on rubber, plastics, and painted metal.
• Spray Polish & Instant Detailer: Restores shine to cowlings, visors, glass, and gauges; anti-static finish repels dust.

5. Heavy-Duty Outboard Covers

Protect your engine when not in use with genuine Yamaha covers made from SurLast® polyester. UV-, mildew-, and water-resistant, with a soft inner liner, snap buckles, and stretch cord for a snug fit.

6. Genuine Yamalube Engine Oils & Change Kits

Use factory-engineered Yamalube oils designed for marine stresses—high rpm, salt, and load. PartsVu offers complete oil change kits with the correct oil weight, filter, and gasket for your Yamaha model.
