Brushless motor size

[carcrazy]

Hey guys I just got another boat. The little miss geico 17" and want to go brushless. I am looking at the hobbywing 2840 3900kv motor. It says its a 380 sized motor. The can size says its 31mm diameter for the can and the length is 46mm but a total of 60mm with the shaft. There is also a hobbywing 2040 4800kv motor that is 20mm diameter can and with can length of 40 not including the shaft.

So I measured the stock can and from what I get from it the can is 30mm diameter by 44mm length not including the shaft. My concern is that the can of the 3900kv motor would be really close to the hull and worried about hull flex and it hitting. So I was wondering if the 2040 would be ok to run in it. I was almost thinking because it's almost 1,000kv more that it would help make up for the smaller can diameter.

As you can tell I am not a motor guy for boats. I am used to r/c cars where I can get a 540 sized motor or 550 lol. Not used to these little motors

Thanks in advance for the advice!

I just took a look at the interior of this boat on Horizon's site.So what is the Dia. of the cooling coil?It would be good if a motor/cooling can would fit in it's place

A rough estimate with my measure tape it is 35mm outside diameter. The motors I mentioned above are the sized without the cooling jacket installed but they come with the jacket.

I was thinking the smaller motor but I am still lost!

I would try to fit something into the stock mount. I wouldn't want to start rippin that little guy up for a new mount and such.

That's exactly what I am trying to figure out. it's looking more towards the 380 sized brushless I posted so far. I just don't want to order the smaller one and it turn out to be to small
