Should be a 9.9 HP-OB, usually 50/1 fuel/oil ratio. 2 stroke TCW-3 oil.

Happy Boating

Some Mariners were made by Yamaha. Look for the Yamaha tuning fork badge on the engine, It is molded in.

When did mercury make a 10 up engine in that time period.

Late 80?s and 90?s. Sometimes call the 10xr and sometimes the mariner was called a Magnum from memory. There were a few variations. Great wee engines.
