mmcfly1074 Because it is very cheaply made boat - water cooling system would increase manufacturing cost. ---- You can purchase aluminum or copper cooling coil (for 370, 380, 390 motor) and install it to the motor in this boat (all are 28mm diameter) -- connect intake hose to jet output nozzle and route into the boat and connect to coil --- drill small hole in side of hull and route the output hose through it. ---- OR goto Creative Channel on YT - he shows how to make jet boats from scratch, easy to copy his cooling system design into FlyTec boat. This would be the cheapest and easiest way.
