Key Features

Fuel Stabilizer – Protects stored fuel – Yamalube Fuel Stabilizer and Conditioner Plus – 12 oz. or 32 oz.. Specially formulated to keep gas fresh during long storage periods, this stabilizer prevents phase separation, reduces varnish and gum deposits, and helps your engine fire up cleanly after months of sitting. Choose the size that best matches your fuel system volume.
Fogging Oil – Shields internal engine parts – Yamalube Stor-Rite Fogging Oil – 12 oz. or EFI Fogging Oil – 32 oz.. Applying Yamaha fogging oil coats cylinders, injectors, and intake components with a corrosion-resistant film. This barrier blocks moisture and air from rusting or pitting sensitive surfaces—one of the most common causes of off-season engine damage.
Grease – Prevents wear and seizing – Yamalube Marine Grease – 10 oz. tube or 14 oz. cartridge. Yamaha’s marine-grade grease is built to handle high-moisture, high-load environments. Apply it to prop shafts, steering linkages, throttle cables, and fittings to keep moving parts from binding up and to fight corrosion in saltwater conditions.
Dielectric Grease (Optional) – Protects electrical systems – Permatex Dielectric Tune-Up Grease – .33 oz.. This small but powerful add-on repels water, blocks salt intrusion, and helps prevent shorts or misfires in plugs, terminals, and other electrical connections.
OEM-Approved Yamaha Quality – Every Yamalube product in this kit is Yamaha-tested and formulated specifically for outboard motors, ensuring proper compatibility and long-term reliability.
Tailored to Your Engine – With size and product options, you can match the kit to your specific outboard setup—whether you’re winterizing a small single engine or a multi-tank offshore boat.
Simplifies the process – Instead of sourcing items individually, this kit brings together the essentials Yamaha technicians recommend—making winterization straightforward and efficient.
Long-term protection – Proper use of these products minimizes downtime, lowers the risk of costly repairs, and keeps your outboard running like new season after season.

Whether you’re putting your boat away for just a few months or an extended off-season, this Yamaha Winterizing Kit takes the guesswork out of the process. With the right stabilizers, lubricants, and protective oils, you’ll keep your outboard in peak condition and ready to perform when it matters most.

FAQs

Q: Do I need all of these products every winter?

A: Yes—each plays a role. The stabilizer protects fuel, fogging oil prevents cylinder corrosion, and grease ensures moving parts don’t seize up during storage.

Q: Do I need both sizes of each product?

A: No—the kit lets you choose the size that fits your needs. For example, larger engines or multi-tank setups may benefit from the 32 oz. options.

Q: How often should I winterize my outboard?

A: Any time you’ll be storing your outboard for more than a couple of months. Winterization protects against stale fuel, corrosion, and hard starts when spring arrives.
