Didnt winterize, or use fuel stabilizer.

[patrolcarr]

I have a 2000 Yamaha 130hp that I used last year for the first time(Was a 2 year old left-over)and put about 125 hours on it. All I did last year was change the plugs. One thing led to another and it has been sitting since mid-November without having been winterized, nor was the fuel stabilized. Where should I start? It was running like new on my last outing, so the engine is in over-all good shape. Does adding stabilizer, or any other additive after the fact help?

Re: Didnt winterize, or use fuel stabilizer.

First thing I would do is change the lower unit oil. Since it is a new motor hopefully no water got in it. If you live in a cold climate and have water in your lower unit you risk the chance of cracking. I would remove the fuel and add fresh gas. Sitting for a few months with gas in the carbs nay have caused them to gum uo. Clean your carbs. Change your spark plugs and your impeller.<br /><br />Good luck

Stabilizer will not help now. wouldn't get to the fuel hose and engine anyway.<br />Fuel may be the only question. Unmixed fuel is not too quick to go really bad.<br />Dump it, particularly if it smells bad; or<br />Test for water, there are kits.<br />Use Water Zorb type product to mix water in old gas.<br />If it is carbed, Yamaha mixes the oil after the carb, Thus you do not have the oil/fuel mix to clog up the carb.<br />Check these and other ideas, add new fuel, and try it. If you have a fuel water separator, check or change the filter now and if practical, after a few minutes of running.<br />OR you can take it to the dealer and have them check it over.<br />Time passes quickly.
