Try a smaller prop or use less voltage (less cells).

Are you using 2S or 3S?...

I have run a 447 2 blade in my Miss Geico. It is Detounged a fair bit and after 6 laps plus mill on a 1/6th mile course the motor comes back quite hot. Good for competition but, not for sport.

I would use a 442 prop to start and maybe a x642 also but amp draw maybe high and not very long run times. A boat can be too heavy even though it's only 31" long.

I would suggest a SwordFish 200 or 220 esc from Offshore electrics.

Offset rudder makes for a faster boat and better handling since water is not spraying on it constantly.

Those are nice but, I've heard quality is not so great once you get it. Loose parts inside or little glue to hold things down. The layer of gel coat is very thin I've heard too.
