Don’t spare the spray.

If you haven’t already sprayed connections with

Yamashield or Yamalube

Silicone Protectant

& Lubricant, remove the outboard cowling and

liberally spray the entire powerhead. Not only

will it help prevent corrosion, but it will help

keep rubber parts (like your cowling seal)

supple and able to do their job effectively.

Note:

Do not spray silicone on any oxygen (O

) sensors that your outboard may have.

We’ve got the goods.

Yamaha offers a complete range of electrical system care products, including original-

equipment NGK

spark plugs, Yamalube Yamashield Protectant and Lubricant, Yamalube

Battery Terminal Cleaner & Protector, Yamalube Silicone Protectant & Lubricant, and

Yamalube Contact Cleaner. They’re the best you can get for your outboard,

and they’re all available through your local authorized Yamaha Marine dealer.
