For good overall performance and value, the QuickSilver Black Diamond is your prop. While QuickSilver Black Diamond aluminum propellers are standard equipment on most boats with Mercury/Mariner/MerCruiser power, they are a perfect replacement for all engine brands through the use of the Quicksilver Flo Torq II hub system. The QuickSilver Black Diamond is recommended for use on boats with up to 250 Hp and with a top speed of less than 50MPH. The high quality casting and durable high-gloss Phantom Black finish make it easy to maintain & repair.
