Boats are very tricky to set up to be able to run them crazy fast..But anyways this should give you some more speed and shorter run times, check to see that the boat is not getting too hot with any prop change that you do.... what size is the stock propeller.? **Q: Will this prop fit on a tracxxs m41?** A: you will need to mic your shaft and then you need to know the blade direction . there are too many models of M41. I bought a mic to check the shafts --Neiko , 01407a **Q: Is this left hand or right?** A: Left ## Frequently Bought Together - Mxfans Diameter 4mm Shaft Center Hole RC Boat Propeller 2 Blade Brass Boat Parts Diameter 37mm Pitch 1.4 - Cheerwing 25" RC Brushless 30 MPH High Speed Boat Large Racing Remote Control Boat for Adults and Kids - Dynamite Grease Gun with Marine Grease 5 oz DYNE4200 Miscellaneous Boat Accessories --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/94129608-mxfans-diameter-4mm-shaft-center-hole-rc-boat-propeller-2](https://www.desertcart.jp/products/94129608-mxfans-diameter-4mm-shaft-center-hole-rc-boat-propeller-2) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-14*
