Model #85ESL70d<br />Serial# J3333568<br />Ok im new to boating and just bought a 1980 Tidecraft bassboat with an 1975 Jounson 85 hp motor. I have a 5 gallon gas can and from what ive read you mix the mixture 50:1. How much oil do i need to put in it for 5 gallon. The old fuel we dumped out looked more like oil. The oil bottles we get come in 1 pint bottles(16 oz). Does this mean i need 64 ounces of oil per gallon of gas.<br /><br />Also even tho fuel mixture isnt right will it still start, we got motor started 2 times but couldnt keep it running??? How many times should you have to prime the motor. We put 1 pint of oil to 3.5 gallon but failed to keep motor running and eventually killing battery.
