Ok so found an even better designed jet drive by Mickieb from Offshoreelectrics.com. It's a 30mm jet drive unit that has a 3 blade machined impellar which is much better quality than the kmb jet drive. I have also found that it will be best to mount a jet drive on a flat spot rather than the V shape. So i will be cutting about 8 inches off the bottom of the boat. It will be an angled cut so as to not cause cavitation. I am not sure what material i will use yet to fill it and make a spot for the jet drive. I have some sheet metal in the shed and i believe that could work but wont know until i get some definite dimensions of the jet inlet. I also found a motor that will work without soldering on the vxl-6s esc and i will be using it. It's a 1790kv motor. So on 4s, it will be close to the rpm max of the jet drive unit. Should be good for the price.
