MJet-35 jet drive in a 4G hull on the lake

This is a fiberglass 4G sprint boat being driven by a hobby star 3670 4 pole 1200 kv motor, a hobby star 130A marine ESC, 2200mah 130c 6s graphing Lipo battery, all spinning an M-Jet 35 pump. It’s designed by Stepan Muller. You can get more info and the plans/files here - www.cgtrader.c...
This run is on Lake Jackson near our house we are in our ski boat I’m driving both boats and my wife is capturing the run. The little boat is quick, it topped out at 31.7 mph! It will run around 6.5 minutes with a lot of fast running before it needs another battery

Thanks , it’s because it’s a great design, all I did was try not to run it over with my ski boat !!!

Sick bro, thats one way to get a top speed. I hope to hit the water this weekend, I have some small gps units (bicycle) so i will grab a top speed. I was at 23 mph i think with the mjet 30, i have to believe the 35 should get 40mph easy. Hopefully closer to 50mph. I think your boat can be much faster, the PLA prop might be costing you top end. I want to get a 6s battery to try out, that should RIP! or is that R.I.P.? LOL

Very nice, how long is the run time

[@DeltaAPmech]

well at full throttle constantly its only about 3 min, but its usually 5-6 depending on how hard its pushed

[@DeltaAPmech]

31.7 mph! The little boat really scoots !!!
