I can answer this... I think...
Let's start with the Shockwave 26... 1500KV power system out of the original Miss Geico (45A ESC and 1500KV 6-Pole BL Motor)...
This boat would perform very well on 3S with the 1800KV motor. And it would be a "safe" setup (reletive to how much any of these systems are "safe")...
If you want to run a pair of 3S packs in the IM31, then doing it with the 1500KV motor would definitely be a "safer" setup than using the 1800KV motor, at least with the current generation of motors. 1500KV will draw less amps, given the same prop, which is important because the motor wires are relatively small gauge.
I'm not sure which IM31 version you have. If you have the 80A ESC, then you have quite a bit of headroom, if you keep the props reasonable.
I have data recordings that show 54-56mph with the 1800KV motor on 6S in my IM31, pulling around 85-95 Amps... That was with an ABC 42x55 prop. About 48-51mph is about what you can expect from the stock prop on 6S.
The 1500KV motor will have more torque, and can handle a bit more prop. You'll need more prop to get the same speeds as the 1800, however, you should be able to run more prop without taxing the system that much.
As others have mentioned, the contacts on the motor/ESC wires are going to get hot after hard runs... If you are capable, I'd replace them with at least 5.5mm...
Hope this helps...
