at this point empty the tank, drain the fuel bowl, remove the drain screw and blast some carb cleaner in it. next year stabilize the fuel and if you can start it up every month. or, if you are not using it often purchase some synthetic fuel. zero ethanol and premixed. . great storage fuel for small engines.I bought a used chainsaw from a neighbour, cut some stuff in the fall and a Christmas tree in December. I still have all my toes.
Then I put it under my boat in the garage. What should I have done? He says it has premium in it.
If my boat sits for a month I need to pull the carb. Yammy 8hp. Getting pretty fast at it but it’s a pain in the arseI’ve come up with a plan to keep my 9.9 Yamaha happy. I’m going to remove the ethanol from the gas in 3 gallon batches. My day tank is 3 gallons and I use it for no ethanol fuel. To make that 3 gallons last a long time I will run the fuel from the main tank which has ethanol in it. With 15 minutes left in each trip I will switch to the day tank and flush it of the ethanol blended fuel. That way if the motor sits for a while it won’t affect it.
The synthetic fuels are pricey. My Yami big block 9.9 is probably the best kicker I have owned. I’ve had this one since 2006 and who knows how many hours on it. I also can work on it myself with my eyes closed. So when an issue like crappy fuel pops up I can fix it today and not pay a shop. I also have another mint low hour spare.. so when the time comes…. no mods to the boat just switch them out.or you could save yourself all that headache and just buy trufuel from home depot.
or get a suzi efi engine
or get an electric motor.
Said no one ever!!!I'm not going to miss the annual carb clean.
