Hey guys,im busy building a mono vhull and war wondering about a brushless motor that has enough power to make it go real fast.first choice was the turnigy 5692 but i just cant find one in south africa,so the guy at hk recommended the hk3674,1660kv,2-6s,1600w power.you guys think this motor will have enough power to swing a prop of maybe 63mm or more without getting to hot.im using a 180-200a esc.thanx
40inch mono v hull motor

LOL!! 63 mm prop on a 3674. Props that size is normally for 26cc gassers.
I think you'll need a 4082 at the very minimum. A 1250 kv on 6s2p and a 45-47 mm prop would get you about 60-70 km/h.
Or, if HK ever stocks up on their 5692 again, a 1320 kv on 6s2p and 47-50 mm prop would be nice too, and you'll probably be doing something close to 80 km/h.
What speeds are you aiming for?25" Arrowana with Etti 2970 3300kV. RCMK Flying Cat with twin HOR Outboards. 2 x SSS 4092 2140kV. Faluga 45" with Leo 56110 620 kv on 12s.Comment

It's a big @ss motor! Make sure the rest of your drive line is up for the task.25" Arrowana with Etti 2970 3300kV. RCMK Flying Cat with twin HOR Outboards. 2 x SSS 4092 2140kV. Faluga 45" with Leo 56110 620 kv on 12s.Comment

Start with some plastic props...

.....and try them out before spending $$ on metal props. They might not hold up for very long but they should atleast tell you if you're in the ballpark. And 47 mm - 50 mm is for a 5692, not a 4082. If your settling for a 4082 then get a 45 and a 47 of these

If you are going to be happy with 60km/h then you can run this 4074 from hobbyking on 4s with an x442 or an m445 and get around 70km/h out of it without straining the system, but a 4082 would be perfect, you can get those in Leopards, but the 4082 is out at Hobbyking.
Run it on 4s with a T180a ESC

If its going to be a fixed shaft tube then i would angle it down just a bit, i have a few boats with fixed drivelines and they run well this way.NEED PARALLEL CONNECTORS?? QUALITY 5.5MM, 8MM, 8 AND 10 AWG, GET THEM HERE:http://forums.offshoreelectrics.com/...est!&highlight=
