So I'm assuming everyone runs brushless these days. Anyone kind enough to show pics of there brushless motor size and IV and prop would be cool so I can find a brushless system

Details on length weight, budget, speed/endurance preference and hull type would allow people to suggest set ups

Well I would like to see all so I can get a slight idea on what to expect out of going brushless

Brushless will go faster for longer than brushed of the same battery. With any power train it has to be matched to the vehicle and demand

the Engine measures,depends on how much power [ KV ]

The guys are asking legitimate questions.
Boats vary in size anywhere from 14 inches to 10 feet in length, with different hull type - Deep Vee, Hydro's, Cat, rigger etc.

That would make a list pretty much impossible to produce, there are way to many variables.
Give them something to work with.

How long is a piece of string??<div>maybe if you downloaded the internet and created a calculator to go through it? :/<div></div><div>hehe

Oh and on hobby king they show all the sizes of their motors...
In my case, swap a 380 motor for a 2848 motor increased power by about 10!!</div></div>

what are you building?

Not sure yet was thinking of a 3 to 4 foot cat maybe longer just wondering what size motor and esc ill need to get it up to 50 to 60

to many variables ....
pick a hull and the size your after and we can help...
tons of different combos
bigger the hull the more power you will need...
3 to 4ft is a big jump and thinking of maybe bigger is even more power again..

I can give a few examples, a lot depends on how you want to run the boat - sport running, oval racing, SAW racing, run time expected, etc. The run times I show below are for full throttle racing, less severe running would extend those times.

34" Aeromarine Sprint Cat:
Neu 1527/1250 Kv motor, Castle ICE240 controller, 6S2P/10,000 mAh, x455 prop race setup
55-60 mph running for 2-3 minutes, could run longer if slower

Scorpion 4025/1100 motor, Castle ICE240 ESC, 6S1P/5000 mAh, x455 prop sport setup
45-50 mph running for 2-3 minutes, could double that if running 2P


41" Stryker catamaran:
Lehner 3060/10 motor, Schulze 40-160 controller, 10S1P/6600 mAh, x465 prop race setup
60-65 mph, 2-3 minutes racing, more with 2P

Scorpion 4035/850 motor, Schulze controller, 10S1P/6600 mAh, x457 prop sport setup
50 mph for 2-3 minutes, longer with 2P

These are boats I run so I know they work, no "theory". You can spend more or less, but remember you can have speed, reliability or low cost - choose any two.
