So at the risk of exposing my level of ignorance with boat motors, I will ask this anyway. I just purchased a 1995 Four Winns with a 115 HP Evinrude Ocean Pro outboard on it. The motor is oil injected and I am wondering if I should use a high grade of fuel or is regular unleaded sufficient?

Re: Fuel Type

i would use 87 octane with marine grade stabil in it. Ethynol is bad news andeven the higher octanes are starting to have it in it.

Re: Fuel Type

Premium gas is for high compression performance engines which you do not have, 2 stroke outboards are pretty low compression engines so regular unleaded is fine.

Some folk swear by the preminum but it really gives you no advantage and just drains your wallet.
