Old Gas

[FishingwithJake]

Last night I tried taking the old fishing boat out. The 9Hp Evinrud had a tough time running but in the past has always been a one-pull starter. The gas hasn't been used since last year, so I'm thinking I need to empty it and get new mixture. I live in Arden Hills and was wondering where to dump old gas? Also, what is the rule of thumb for mixing outboard motor oil in gas? (ounces per gallon?)

Jake - I'd dump the old gas into your truck or car. Some folks will disagree with me, but I've never had a problem with it - if you're concerned simply fill the vehicle up after. You can use a transmission fluid funnel and it will make less mess.

May wish to run a tank with some sea foam through - or if you don't run a bunch only fill the tank half way. Your oil mixture is 50 parts gas to 1 part oil, or a pint to six gal, half a pint to 3 gal. You can get a measuring vial at most marine dealers, the actual ratio is 2.56 oz oil to gal of gas if my cipherin' is right....

Jake, I agree with NewYankee. Dump it into the truck tank and get some new non-oxy gas. It has a longer "shelf life" than reg unleaded. But then, Treat it with Stabil(personal Preference) or Sea-foam AND put in Amsoil premix 100:1 Sabre oil. The treated fuel will last longer than the reg unleaded and the Amsoil will make your 9hp run like a different motor. Check out the current thread on Amsoil, The stuff is impressive!! I AM NOT a sales person, I AM A USER!! Can you imagine, starting your 9hp WITHOUT a blue cloud? How about backing up and actually SEEING the water behind you??? The stuff IS worth the money!!

New gas should fix it. Use only a little sea-foam to help clean up the carb passages and clean out some of the deposits. Use it only as directed though or you could burn up the motor. Standard mix is 50:1. Research the Amsoil thing, it is a good product but there is a dark side to the story also which I will not get into. Stay with the tc-3w rated oils until you are comfortable your engine is running the way you think it should. If it does not come out of it, the carb may need to be taken off and cleaned. Stabil is a good product for preserving fuel. Remember this though, it will slow down the breakdown process of the fuel, it will not stop it. Left over winter even with stabil in it, it will still go bad.
