Oil Gas Mix Question

[zqx]

Can you give me a ballpark ratio of two cycle engine oil to gas for a 1985 Johnson 90 outboard. I am just looking for an approximate ratio. Anyone with experience with a Johnson outboard, please respond.

Howdy zqx.<br /><br />Welcome to iboats. <br /><br />Your engine calls for EXACTLY 48:1 mix, which we usually call 50:1. That is one pint of TC-W3 rated outboard oil to 6 gallons of 87 octane unleaded gasoline.<br /><br />Good luck.

But only if we're talking American gallons!<br />The British gallon is different.<br /><br />As JB said .....!

Re: Oil Gas Mix Question

50:1 is 20ml of oil per litre of gas if you don't come from a silly country.<br /><br />Now that gas has hit $1/l here it's really convenient. You put in $40, you put in 800ml of oil.<br /><br />garydoole, I think you've proved to me there's no such thing as common sense! <br />(Except if you talk fractions. Oh, how I wish metric used fractional measurements!)

Re: Oil Gas Mix Question

your mixture should be 2% oil which is 50:1 or 1 litre for 50 litres. However if you are running in a new motor 4% is goog to start with as it lubes everything but smokes a bit.<br /><br />------------------<br />Bon vent and look where you're going

Re: Oil Gas Mix Question

Can someone tell me if there is such a thing as a manual trim for an outboard engine. Have an old Johnson 90. Don't want to spend the money for an automatic hydrolic trim. A hand crank type of trim would be fine.
