Just acquired a Johnson 112HP SPL motor without oil injection - this is replacement for a 70 HP Johnson with oil injection. Anyone know what the correct oil/gas mixture is?
Those are two different engines. The 70 is an inline 3 cyl. The 112 is a V4. The 112 makes some nice torque and hp. It's identical to the 115 that year, but has the cheaper fuel pump.
