Ain't gonna hurt it a bit to use a good grade of regular, unleaded, non-alcohol gas.

In fact, "in the day" they used to recommend white gas in outboard. Tetraethyl lead was NOT a beneficial additive for outboard fuel EXCEPT where it related to octane improvement. Otherwise the lead just caused more deposits.

Tell your buddy to put some Chevron in there (or other Name Brand, quality non-alcohol fuel), use some Good 'Ol Wal-Mart-Special Penzoil Synthetic Blend TCW-3 motor oil, and she'll run like a champ!

You didn't say what size, but the only exception to using unleaded would be if it's a 135HP V4. They're quite hi-strung and should use Premium unleaded. In fact, those motors had a special low-compression head gaskets that were recommended by OMC as a refit.

Also tell him to give it a Seafoam or Techron treatment and it'll run better yet. Check out the tech info at the Seafoam site:
