Product Overview --\u003e\n  \u003ch2\u003e🚤 Premium Zinc Alloy 4-Blade RC Boat Propeller – CW \u0026amp; CCW Pair for 55mm\/60mm Shafts\u003c\/h2\u003e\n  \u003cp\u003eLooking to boost the performance of your remote-controlled fishing boat, bait boat, or general RC vessel? These high-quality zinc alloy 4-blade propellers are the perfect upgrade. Unlike flimsy plastic props that can crack under load, these metal propellers are built to handle higher RPMs and provide consistent thrust in the water. Whether you are running a twin-motor setup and need matching clockwise and counter-clockwise pairs for a stable, straight ride, or just replacing a single broken prop on your 55mm or 60mm shaft, this set has you covered. Available in five vibrant colors and multiple configurations, they are an affordable way to give your boat more torque, better speed, and a great custom look.\u003c\/p\u003e\n\n  \u003c!-- 2.

CCW stands for Counter-Clockwise, meaning the propeller turns to the left. Twin-motor boats typically need one of each to cancel out torque and keep the boat steering straight.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"faq-item\"\u003e\n    \u003cspan class=\"faq-question\"\u003eWill these 4-blade props fit my 55mm or 60mm RC boat shaft?\u003c\/span\u003e\n    \u003cp class=\"faq-answer\"\u003eYes, they are designed to fit standard 4mm motor shafts. The 55mm or 60mm listed in the title refers to the outer diameter of the propeller blades, not the shaft diameter. Please confirm your motor shaft is 4mm before ordering.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"faq-item\"\u003e\n    \u003cspan class=\"faq-question\"\u003eCan I use these metal propellers as a direct replacement for my plastic RC boat prop?\u003c\/span\u003e\n    \u003cp class=\"faq-answer\"\u003eYes, you can, provided the shaft diameter matches (4mm). The zinc alloy prop is much sturdier and can handle more power. Just be sure to add a small amount of thread lock or use a set screw to secure the propeller to your shaft, as it may be slightly heavier than the plastic original.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"faq-item\"\u003e\n    \u003cspan class=\"faq-question\"\u003eWhy do I need a pair of these propellers (CW + CCW) instead of just one?\u003c\/span\u003e\n    \u003cp class=\"faq-answer\"\u003eIf your RC boat has twin motors or a dual-drive system, running two identical CW propellers will make your boat spin in circles. You must use one CW and one CCW propeller to create equal and opposite thrust for stable, straight-line performance.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"faq-item\"\u003e\n    \u003cspan class=\"faq-question\"\u003eWill the bright color coating wear off in saltwater?\u003c\/span\u003e\n    \u003cp class=\"faq-answer\"\u003eThe plated finish is designed for general freshwater use. While it has good resistance to corrosion, extended use in harsh saltwater environments may eventually lead to some dulling or chipping of the decorative finish. For the best longevity in saltwater, rinsing the prop with fresh water after each use is recommended.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n\u003c\/div\u003e","brand":"HomeDIYer","offers":[{"title":"55mm (φ4mm Bore) \/ Shiny Gold -
