These general purpose three blade stainless propellers offer superior performance compared to aluminum, with thinner blades, higher resistance to flex and improved repairability. They feature a modular design, which means that installation requires a hub kit, which is sold separately. Models offered for use with 40-350hp outboards and sterndrives.Key FeaturesFive time more durable than aluminum propellersMore repairable than aluminum propellersThinner blades (compared to aluminum) flex lessModular design requires separate purchase of hub kitModels offered for use with 40-350hp outboards and sterndrivesHow to Select a PropellerFor an overview of how to select a propeller, see our West Advisor article "Selecting a Propeller", located in the "Advice" section of this page. For a propeller appropriate for your application and to identify a hub kit for your application, see the Quicksilver Propeller Selection Guide, which covers Silverado and other Quicksilver propellers.The Advantage of the Quicksilver Modular Propeller SystemThe Quicksilver Modular Propeller System (Search: Flo-Torq II Hub Kits) enables you to easily switch props, change pitch, change from aluminum to stainless, or replace a bent propeller. Just remove the old prop and slip on a new one. When large underwater obstruction are encountered, the Delrin sleeve of the Flo-Torq II System is designed to "break away" following impact, ensuring that damage to the engine, engine drive and propeller is kept to a minimum. And better yet, the sleeve can easily be replaced by you! Competing hub systems take longer to break away after impact, increasing the risk of major damage to both the engine and the drive.
