I am a new owner of a 1978 115 horsepower Evinrude motor and boat. When you fuel the boat up do you have to put a oil mixute in with the gas. Forgot to ask old owner this stupied question. i appreciate all the help:)

Depends on the size of can. ;)
Total oil in NRN would be 1.6 pints or .8 litres for the 10 gallons of gas.

Re: Question about fuel mixture

Just get an oil measuring bottle and a gallon of oil. There are marks on the bottle for how much oil to add based on the gallons of gas you are putting in.

All you have to do it fill it up to the 10 gallon line and dump it in. If you are only putting 7 gallons in for whatever reason, then fill it to the 7 gallon line and dump the oil in. Makes life a lot easier and costs like $5 at West Marine or any marine store.

I have those measuring jugs all over the place now. Makes it simple.
