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.
Except running it dry everyday will shorten the fuel pump life. The Yamaha fuel pump diaphrams are a weak point already.I agree with all the sentiments about EFI, but if you have a carb engine its not a mystery on how to deal with this.
Step 1: Run it out of gas. Just disconnect the fuel line and wait till it conks out
Step 2: Afterwards, open the drain screw at the bottom of the carb float bowl and drain any residual fuel (there will be a few teaspoons even after running it out of gas)
Step 3: Don't use old fuel, and use stabilizer on what you have
I have a 2 year old 6hp Mercury 4-stroke kicker. Its one of those rattle can single cylinder motors that have a reputation for being hard to start and constantly clogging up carbs. I only use mine periodically, and it sits for extended intervals. Doing the above, it starts first or second pull, every single time. Most people never drain the bowl, and you will be surprised how much fuel is left in there even after running it out of gas.
if you want to get really pedantic about your fuel, run your kicker off a Jerry can and then just dump the rest of the fuel into your vehicle after each use - done - fresh fuel every time out.
Please don't read this as disrespectful, but you've identified that the motor + gas is the problem, yet you intend to keep the motor and the fuel.The synthetic fuels are pricey.
