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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Ok for aquacraft sv27 *by M***N on May 16, 2020* We did get a lightly bigger motor but this propella made the boat so fast we couldnt even drive it full speed. ### ⭐⭐⭐⭐⭐ Great R/C Boat propeller. *by J***N on October 22, 2019* This prop made a huge difference in the performance of my R/C racing boat. ### ⭐⭐⭐⭐ Find new top end speed *by K***N on August 23, 2020* This was fast to change.
