Cant find the answer to this question

I have a Tekin 5.5 turn 540 motor for a car.LHS guy says its a 2s motor.No where on the box does it give the KV.I know how to figure the max rpm on FE,but I dont know how to figure max rpm using the number of turns.Is there a formula using the number of turns and voltage to figure max rpm?
Id like to use this motor in a boat since I have a cooling jacket that will fit,and need to run 3s.Any info would be appreciated.

Tekin's site lists the motor kv for a sensored redline as 7,700kv (assuming it is that one)
so far as I know there is not set turn to kv formula, differs between manufactures.

Thats the one I have.Thanks alot.

A Novak 5.5t ballistic is 7400kv, so the 7700 is most likely correct................making it a 1s motor........

You should get a much lower kv motor for your boat.............

I just had it laying around for my Blitz.I was thinking of using it in my rescue boat just to have a faster one than my friend with the same boat.
