Yamaha Outboard Engine Covers FAQs
Are Yamaha Outboard Motor Covers Worth the Investment?
We get it. Yamaha outboard motor covers are yet another thing you are told you need to buy for your engine. But is this investment necessary? This area is subjective in some ways, but in other ways, it is not.
One issue is cosmetic. Do you want your Yamaha outboard’s cowling to look new and shiny for as long as possible? Yet another issue is not cosmetic but is part of your overall effort to maintain your engine. Your Yamaha’s cowling is like the skin on your body. Just as our skin does a great job of protecting our body’s systems, your cowling protects its own precious cargo—your engine.
Just as our skin takes a lot of abuse—sun damage, cuts, bruises, environmental contamination—so does your cowling. In the southern states, UV rays are especially intense. For example, boats and engines alike spend a lot of time baking nearly year-round in the Florida sun. In the northern states, boats may not be exposed for as many months of the year and the UV rays might not be quite as strong, but a lot of damage can still be done.
Another source of harm is trailering. If you trailer your boat, your cowling is likely to be struck by stones, rocks, and other road debris as you tool down the highway. Scratches and dings are the low end of the damage—cracks and punctures in your Yamaha cowling are more serious.
Finally, environmental elements like saltwater spray or acid rain could collide with your cowling at some point. Yamaha outboard covers do not eliminate all of these problems, but they sure do help a great deal.
Yamaha outboard motor covers are made of durable SurLast solution-dyed polyester fabric. SurLast fabric offers strong protection against the harsh marine environment. The fabric is nonabrasive; water-resistant; and resistant to UV rays, mold, and mildew. Yamaha outboard engine covers are also designed to perfectly fit your specific Yamaha outboard engine model.
Your Yamaha cowling will become damaged by the sun, road debris, and other environmental factors if it is left uncovered when your boat is docked, on a lift, in storage, or being transported. Given this, we think it is best to calculate the risk-reward ratio of investing in a Yamaha outboard motor cover and go from there.
Cost of Yamaha outboard motor covers: $35 to $152, depending on engine size
Cost of a new Yamaha top cowling assembly: $300 to $1,900
Cost of refurbishing and repainting a Yamaha cowling: $350 to $750
Cost of Yamalube Marine Spray Paint: About $21 to $45, depending on engine size
Cost of Yamaha OEM replacement decals: $62 to $130
Cost of your time: Add your own dollar amount here.
So, you be the judge. We believe Yamaha outboard motor covers are well worth the cost to protect your outboard when it is not in use, but you will come to your own conclusion.
Proper Yamaha maintenance requires genuine Yamaha outboard parts and products – PartsVu is happy to help.
How do I protect my Yamaha outboard motor?
Grime, oil residue, salt buildup, rust, and corrosion. These are all good reasons to clean and protect your Yamaha outboard on a regular basis. Performing routine maintenance will keep your Yamaha running reliably and at an optimal level for plenty of fun on the water with family and friends. A little TLC can recover lost engine power, maximize efficiency, protect from the harmful effects of corrosion and ensure a long and healthy running life for your Yamaha outboard.
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.
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.
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.
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.
How do I take care of my Yamaha outboard engine’s exterior?
Yamalube spray polish and instant detailer is a quick detailer that will restore a lustrous shine to paint, chrome, glass, and smooth plastics like visors, engine cowlings, windshields, and gauges. Gives textured plastics, rubber, and vinyl a beautiful satin finish. Anti-static properties repel dust and dirt to keep a long-lasting, ship-shape shine.
Yamalube External Engine Cleaner is a powerful engine degreaser and engine cleaner that powers off grease, mud, and grime. It is safe for use on most rubber, plastic, and painted metal surfaces.
How do I customize my Yamaha outboard engine cowling?
Could your Yamaha outboard cowling cover use a face lift, or maybe you just want to add a bit of custom personality to your boat?
PartsVu now carries Yamaha Custom Cowling Graphics, in eight different colors, for the F225, F250 & F300 4.2L V6 offshore motors.
Also, PartsVu carries Yamalube Marine Spray Paint. The durable enamel coating of these spray paint products, in factory-matched colors, provide excellent coverage against the elements. Everything you need to restore or customize your cowling cover.
Yamalube marine spray paints are high-quality, factory-matched spray paint for touch-ups or full overcoat application. This durable enamel coating provides good performance in the rigors of the marine environment. As is the case with any painting task, surface preparation is very important. Note that paint may fade over time on an outboard motor exposed to the elements over time, so the factory-fresh color supplied in this can may not match older paint exactly. Therefore, the application area may need to be larger to provide for proper blending of the color.
