my mariner (jap version 6E9) was pushing a Marina 12 foot speed boat with a very deep v hull I tried several props but it perfomed best with the Black Max and believe me it was fast. The engine was using Castrol "Power 1 race" 2 stroke for bikes it is 100 times better for your engine than outboard oil, I guarantee you.
Fuel mixture 40:1 no other mods just clean carbs, I've tried tuning outboards and it can't realy be done as they are on the limit now THE OIL MAKES THE BIG DIFFERENCE!
