Ethanol-containing fuels (E-10) have been wreaking havoc on boat and PWC engines. I’ve experienced the problem firsthand, after a brief storage period left me with a gummed-up carburetor. E-10 can separate into layers — gas up top and ethanol and water below — making engines extremely difficult to start. It can also hasten the development of gum and varnish. Yamalube Fuel Stabilizer & Conditioner

Yamaha recently announced a product that can combat the problem — Yamalube® Fuel Stabilizer & Conditioner Plus. I have yet to try it firsthand, but Yamalube is quality stuff, so I’m planning on giving it a go as soon as I get my carburetor rebuilt.

According to Yamaha, the proprietary formulation will keep fuel fresh, potent and free from gum and varnish.  Metal filmers in this exclusive formula protect marine engines from the harmful effects of E-10 fuel and the destructive sulfate salts that corrode metal components in the fuel system and clog fuel filters. Yamaha claims it’s the only fuel stabilizer and conditioner today that delivers this high level of protection.

Yamaha recommends using a continuous mixture of one ounce of Stabilizer to every three gallons of fuel. The product is available at all Yamaha dealers. A 12-ounce bottle retails for $5.38, 32-ounce for $13.81.

A little more hassle, yes, but trust me, it beats the alternative…
