50:1. Use a good TC-W3 outboard oil and you will be fine. Consider doing a decarb on the engine to ensure the rings are free and not sticking. Use Seafoam or one of the other combustion chamber cleaners out there

1 pint per 6 gallons regular gasoline will give 48 to 1 ratio-- nothing to think about. However, most portable tanks will actually hold about 6 1/2 gallons. 1 pint oil will give 52 to 1 which is acceptable. Again, nothing to think about.

Just purchased. Do I mix oil and gas in tank, if so, what's the ratio? Thanks

Welcome to iboats.

Probably the single MOST important thing that should be on your list to purchase is a proper manual for the motor. iboats people are always eager and willing to help however, many go boating ;) and are unavailable.

Have fun and be safe.
