Re: gas/oil ratio
Hey Sarah, don't sweat the sarcasm - it's probably meant in good humor.<br /><br />As for oil selection, just use any oil that's marked "TCW3". It is probably also prominently marked for "two cycle outboard motors" or such. You'll find many choices (with surprisingly wide price range) at gas stations, variety stores (e.g. Wal Mart, Fred Meyer), boat shops and hardware stores. Pick your price point, convenient location, or favorite brand and go for it and don't give it a second thought.<br /><br />As for mixing: I also use built in tanks (2 @ 25 gal ea.), but often fill from 5 gallon cans, so the pt and qt. thing doesn't work for me. I have a container for measuring oil on which I've marked for 5 and 10 gallon increments at a little richer than 50:1. (~13.5 and 27 oz). I err on the rich side thinking it's better if I'm a little inaccurate in filling or pouring the oil. Even at the pump, for simplicity, I almost always just use 5 or 10 gallon increments and accurately dispense the oil for that amount. So, often my tanks are a couple gallons short of full. If I really want to top off to the last 2 or 3 gallons, I just use the 5 gallon mark on the oil container, and call it good. The overall mixture is going to be close enough until I top off again - especially since the most common mixture the manufacturers use - one pint to 6 gallons - is actually 48:1, not 50:1.<br /><br />I guess my point is I find it so much easier and less messy just to do this "two increment" system rather than figure out and measure the number of ounces needed for an exact amount of gas every time I fill up.
il ratio for a 83 70hp Evinrude? I know it is 6:1 and this may sound really stupid, but is that 6 gallons to one quart or one pint?
