Rotomax 50cc Equiv?

[FighterCat57]

Any thoughts in putting this in a boat?

I'm pretty sure I can spin it up a bit more. It's pretty low kv. I'm thinking ~90v and 17,000 rpm approx. which puts it in line with gas props.

Its a big motor but unfortunately its only rated to 44 volts or 12S. Dont know if thats due to RPM limitations or its simply an electrical diaelectric issue with insulation. But I dont think it would fair well on 90 volts. What is curious, and leads me to believe in the electrical insulation issue is the low Io. Just my 2 cents.
