My IM31 has the Hobbywing Seaking 90amp esc. OSE upgraded flex shaft. Just looking for a suggestion on which Leopard motor my esc can handle. I am running it on 5s with the stock motor. It's running 43mph right now. Looking to hit 50mph.

Hi Whiteracer,
to hit 50mph, you should need an 4074 1650kv or 4082 1600kv Leopard motor. It's important not to go over 1600kv, to stay under 35000rpm to provide small stress to transmission and hull.
But anyway it's not simple as it seems because to go 50mph for few minutes longer you need strong batt with min. 45- 60C rating and it means that your esc is
also to review and also the propeller.
I would like to hit 50mph too, but I put ALL upgraded parts what OSE store offers for IMP31 and I go on 6s.
My combination is: SeaKing 180A esc + 4082 Leopard motor + 6S batteries and ALL other upgraded parts for IMP31V2 that Ose store offers ( flex cable, trim tabs, turn fins, dual rudder, propeller Oct. M445, as you can see I changed all things that was possible to change!
Just with this equipment you'll have an reliable setup for 50mph.
Now I'm waiting the summer to try it.
Salute, Niky.
mine : leopard 3674 1700Kv on 5s , 43 mm cnc ,120 a esc
easily breaks 75 km/u ,runs stable at those speeds,everything cool
it will turn a 45 mm and hits 80km/u ( 50mp/h) but only on glass water!, becomes rather tricky once getting close to the 80km/u even in small waves

My IM31v1 has been running a Leopard 4704, 1800kv, Seaking 120A ESC, 5S 40C batteries (parallel), Octura x645, nearly two years. GPS'd @ 58mph. Very stable, no chine walking. Prop-shaft is raised slightly.
