Mercury Black Max Aluminium 19 inch Pitch 19P Propeller.
Mercury Mercruiser Black Max is the world’s best-selling propeller. No other prop on the market today provides as much performance, durability, and value as a Black Max aluminium propeller. It’s designed to be the perfect complement to a Mercury outboard or Mercruiser stern drive – that’s the reason Black Max propellers are installed as original equipment by more boat builders than any other propeller in the world.
If your replacing your existing prop and are not sure what size you have, look between the blades and you will see stamped into the casting, a figure such as 15P. This means you have a 15 inch pitch prop.
To correctly size your prop, the boat should be tested with a clean bottom, a full tank of fuel and one person on board. If you can reach maximum revs as per the engine spec, then you have the correct prop fitted. If the engine over revs, go up 2 sizes, i.e. from a 19P to 21P. If you cannot reach maximum revs, then you will need to drop down 2 sizes, i.e. from 21P to 19P.
Each Mercury Black Max propeller is supplied with a Flo Torq II Kit, Part number 835257Q1 suitable for an Alpha One Gen 2 Sterndrive.
