LICHIFIT RC Jet Boat Underwater Motor Thruster 7.4V 16800RPM CW CCW 3-Blades Propeller for DIY Micro ROV Robot RC Bait Boat Submarine Accessories

I used these on a toy boat and they worked great. I’ve kept them submerged underwater the entire time and water didn’t even phase these motors. I wish they were more powerful but that might be on me because of the battery I used.

Works great, people having issues need to understand that the watts and volts matter on these for the power source.

Both motors stopped working between 30 sec. and 1 min.

Take up less room and very powerful for underwater drone.

As other reviewers have noted, quality control is lacking. The units seem well built. However one of them would not turn on straight out of the box. I am returning them.

I used both motors.. the first literally burned up in 2 min on a 6 volt battery. The second I used a 12volt battery and it had stopped within about 5 min. Waste of money.

Not waterproof!! Crap!

So far they work great as part of rc boat build with fly sky controller/receiver and a 5000 mAh battery and ESC. Will update if they short out.
