This 3660 comes out of the side

Look close at the pic - It says "L-4074-2200KV"

[Make-a-Wake]

Well crap...................thats retarded to use that photo. I wonder what the 3660's really look like now...................?

[Make-a-Wake]

This link shows a schematic of the motor at the bottom................shows the wires out of the top.....................hmmmmmmmm.

I agree. Take a look at the first link, it has a drawing showing the wires coming out the top. I would think an extra 4mm on the dia. should be fine.

[Make-a-Wake]

Me too, 2mm per side really....hope you dont overpower the drive on those PB outboards with the big 40mm 4 polers.

Would the esc's handle those motors? I'm not sure which wind to get.

[Make-a-Wake]

I'd go with the 1900kv........................4s would be plenty..........you could run a couple of these props - http://www.offshoreelectrics.com/pro...od=dh-aqub9760

Make sure the 40mm jackets arent too wide diameter-wise if you still want to use the cowl. The t120's should handle it fine.

EDIT - just realized those props arent L/R available................you could use Octura x442's they come in L/R rotation.

i have a suggestion for a cowl, i have used a cowl from a proboat blackjack 26 really not the whole cowl just the cockpit maybe you could do the same with a blackjack 55, i assume your boat is 42" i know the bj 55 is larger you maybe able to customize it using to fit your needs

Cool....another twin outboard build. Were there so many outboard builds before I came in here?

I've had this in mind for quite a while now. First I was going to put twin OS 21's on my Dumas Skater, but I just didn't feel like messing with nitro anymore. Then the electric outboards just didn't look right on the Dumas. 2 boats & 3 sets of motors later, this is how my project ended up.

I don't think you'll find right hand cables for the lower unit, but I might be wrong.

Yeah.............thought about that too, its why i posted the 40/57 first.........then thought he may want counter rotation..........he could fab a right hand cable possibly.

[timjz]

Cables are already taken care of.
