Which Motor?

Id go with the 1700kv on 6s but see what others say as well. Martin.

Ok thanks mate..

I'll suggest this 4 pole motor on 6s, it'll be in the sweet spot for rpm's and allow a little larger prop.

But if it were mine, this motor is a nice size, 4065, and has a bit more power than the 3674, it would be great on 6s.

Thanks Martin for the info but looking at other Threads on here it doesnt look good a Leopard 4082 1500kv its just to long, i dont understand why cant i use a

Leopard 4074/b 2150

Specification:
cells 3-6s lipo
cells 3-6s lipoMax Voltage 22v
Max Amp: 120A
Max power: 2600W
RPM: 2150KV/volt
Resistance: 0.0062
Non-load current(7.4V): 1.8A
Diameter: 40.2mm
Length(excluded shaft): 73.8mm
Mount hole depth: 7mm
Shaft diameter: 5mm
Shaft lenght: 20mm
weight: 374 gm

I no the RPM is 47515 and you recommend less than that but im using the right Voltage and Amps, can you explain what the problem with high rpm, thanks

The 6s max voltage specs are more applicable to cars/trucks where the load is not as great as boats. You would have to run an incredibly small prop to stay under teh 120A rating at that RPM.

I run a 3674 in that hull and it does well. A 3674, 4065, 4074 would all do well. The 4074 1400kv is the most powerfull of the bunch there and would turn the largest prop.

Do you think i would get 4065 in the Hull the Diameter is 4mm bigger and Longer?

I doubt that the extra 2mm above and below the motor diameter-wise would not fit..........also your motor is 60mm long, 5mm longer should fit. They use the same bolt pattern, so all you would need to do is mod/grind the motor support a bit and get a 40mm water jacket.
