This is especially important for eFoil and hydrofoil builds where efficient gliding between power bursts extends ride time and improves the riding experience. Fixed propellers create constant drag even when not spinning, reducing glide efficiency.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ2: Is this propeller compatible with motors other than the 65162?\u003c\/strong\u003e\u003cbr\u003eThis propeller is designed specifically for the \u003cstrong\u003ethreaded shaft of the Firduo 65162 motor\u003c\/strong\u003e. Compatibility with other motors depends on the shaft diameter, thread pitch, and thread direction. If you have a different motor, contact us with your motor's shaft specifications and we'll advise on compatibility. Do not force-fit a propeller onto a non-matching shaft.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ3: How to determine whether a propeller is CW or CCW?\u003c\/strong\u003e\u003cbr\u003eWhen viewed from behind the board (water-facing side), a \u003cstrong\u003eCW propeller\u003c\/strong\u003e rotates clockwise under power and a \u003cstrong\u003eCCW propeller\u003c\/strong\u003e rotates counter-clockwise. This is a CW propeller.Most single-thruster eFoil builds use CW. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ4: Can I use this propeller in saltwater?\u003c\/strong\u003e\u003cbr\u003eYes. The propeller is made from \u003cstrong\u003eanodized aluminum alloy\u003c\/strong\u003e which provides good corrosion resistance in both saltwater and freshwater. After saltwater use, rinse the propeller and motor shaft with fresh water to remove salt residue. Periodically inspect the propeller hub and shaft threads for corrosion and apply a thin coat of marine-grade anti-seize compound to the threads to prevent galvanic corrosion between the aluminum propeller and motor shaft.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ5: What if the propeller comes loose during use?\u003c\/strong\u003e\u003cbr\u003eDuring installation, it is recommended to apply a medium-strength threadlocker and tighten the nut. Alternatively, use a lock nut for secure fastening.\u003cbr\u003e\u003c\/p\u003e","brand":"FIRDUO","offers":[{"title":"Default Title","offer_id":46660772135090,"sku":"Propeller-162mm-2","price":42.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0227\/7805\/2685\/files\/1_efc3986d-0415-43d5-898b-1d0f9d3b0015.jpg?v=1761723675","url":"https:\/\/firduo.com\/products\/firduo-162mm-2-blade-folding-propeller-efoil-kayak","provider":"Firduo","version":"1.0","type":"link"}
