  • racing lower unit

    Does anyone know the approximate efficiency of a racing lower unit attached to a 11 HP DC motor running at 3500 RPM

    Typical bevel/miter gears run in the mid to high 90's% efficiency. Most lower units when set up properly will run in this range. Bearings must be good and the proper backlash in the gears is important to get the mesh of the teeth right so the gears run smoothly.
