I have a 30 HP 2-stroke Yamaha on my "23". It has a 10 gallon stainless steel tank under the cockpit floor. Following initial problems with the engine not starting, a mechanic and the BSS inspector both expressed surprise about the fixed tank, and stated a 2-stroke should have a loose tank, that can be shaken to keep the fuel/oil mixed. I have been using a temporary tank with success. Another colleague has told me that modern oils used for 2-strokes do not separate out. What is the general practice for boats with 2-strokes?
Cheers, John |

Id say a shakeable unit. Id also wonder about a fuel tank being far UNDER the level of the engine, and its ability to send fuel sufficiently 'upwards'...having said that tho I wouldnt know for sure being a 4 stroke owner!

| I also believe that an outboard engine MAY have a problem in sucking fuel from an inboard tank that is lying some way away and very low down. Usualy the tank is of 5 gallons capacity and mounted quite close top the engine. I have for free a proper outboard tank with a baynet type connection which I am sure can be changed for a connector to suit your engine if necessary. It appears that some engine manufacturers have their own design of fuel connector; these are normaly very easy to obtaion. If you want this tank it is yours; you only have to arrange collection or pay for the postage. Please let me know. |

Jimbo, Thank you for your very kind offer. However I have taken the decision to go with a new loose tank and have ordered a 30l tank + hose + new fittings. In time I will remove the fixed tank and dispose of it suitably.
As an aside, I have 25 lites of fuel/oil mix that has sat in another (slightly rusty now) steel outboard tank for 20 years! Does anyone have any suggestions as to how I can dispose of it. The Local council tip don't want it, and it's too much to add to a bonfire!
Thanks, John |

| Don't try putting it on a bonfire if you want to be around tomorrow.You could strain it through a very fine mess cloth and use it with a disposable in line filter. |

Why not advertise it on your local online Free-Cycle, (now called Freegle)?
You be absolutely amazed who will take what, trust me!! And they will come to you!

| I was only joking about the bonfire. Did that when I was 16 - never to be repeated! Being 20 years old I'm afraid that it may have "gone-off". Also it's an undetermined fuel/oil mix - not to be risked in my engine. I'll try Freegle. Thanks all. |

| You might find that the best use for this old mixture is as a cleaning / degreasing aid. |

You know...Im getting quite curious, how on earth does anyone have 20 years worth of unused fuel???? And considering natural oil drilled from the deep is millions if not billions of years old...youd have thought 'only' 20 years on top of the previous millions means its still quite fresh..
Cheers Rick |

I'm afraid that I am a "Hoarder". We moved into our present house 20 years ago and the fuel tank+fuel, a British Seagull and a 5 hp Evinrude got put under a bench in the garage, and because I have not had a boat since then, they have sat there. I thought that modern unleaded fuel deteriorated with time, because of all the fancy additives though I'm now told that old 4-Star is probably OK. Regarding the "Billions of years" - Crude Oil probably "gets better" with time - its only when it's refined it starts to go downhill! Now I'm back on the water I plan to resurrect the 2 outboards sometime.
