Flo-Torq II – Evinrude 8M0107220 Protect Your Investment with Flo-Torq II When it comes to propeller technology, only Quicksilver knows what it takes to make the best prop and prop systems. That’s because for more than 70 years, we have been designing and building the best propellers available anywhere. And it is this knowledge and experience that has led us to create the Flo-Torq II. To put it simply, with the Flo-Torq II System, Quicksilver Propellers® now become compatible with and can increase the performance of almost all marine engines. But that’s only the beginning. Because it is specially designed to reduce slippage, yet still flex during engine shifting, the Flo-Torq II cushions and protects the drivetrain from most impacts. Plus, the Flo-Torq II System also provides unmatched corrosion protection – giving you peace of mind and the freedom to make the most of your time on the water. Prop Sleeve At the heart of the Flo-Torq II System, Quicksilver uses brass and Delrin – an advanced, noncorrosive plastic from DuPont® – that virtually eliminate any opportunity for hub corrosion. In comparison, competitor systems use brass, aluminum and plastic components – resulting in a higher probability that the parts will corrode and fuse together. Thus making propeller replacement almost impossible. *Items in image may vary from Flo-Torq II models required for engine type.
