    Comments about Black Diamond Propeller, 15 x 16 LH 4-Blades:

    I replaced my three blade prop a 14.5x17 with a 14.5x 18 four blade diamond 4 and droped my gph to 10gph
    from 15 on a 30 searay sundacer
    my wot is around 44 to 45 able to stay on plane at 2900rpms jumps up on plane quicker and stay there maybe a 5mph loss of top speed but who cares
