Howdy, DLM Mann.<br /><br />That is a 1979 70hp.<br /><br />Fuel mix should be 50:1, 6 gal. unleaded regular and 1 pint TCW-3 outboard oil.<br /><br />Good luck.

Re: fuel mixture ?

Most tanks have a data plate near the sender or filler fitting that gives the capacity. You may have to remove an access plate to get to it.

SoLittle I have a fuel gauge also,,,shouldnt there be wire attached to the tank somewhere..with my head in the well and looking under the deck I can see a plate with (looks like connectors) ....and two wires in the well not attached to anything

Yes, One to sender on tank and the other to ground.

Or, you can fill up a 6-gallon spare tank to carry in the boat. Then run the big tank dry. Switch over to the spare and go fill up the main tank. Add a pint of oil to start, then put in the first 6 gallons of gas, then the second pint, then the second 6 gallons. If you end up with a pint too much oil, doon't fret as it won't hurt anything for a tankful. , just don't run too much on a regular basis....<br />- Scott
