Im currently running a Promarine 34" MTR on 6s. The original motor was a 3674 2075kv SSS and a 120a Seaking. I was told the stock prop is pretty close to an X442. With the stock set up the maunfacturer said an X445 is about the limit. Ive upgraded the esc to a Seaking 180a and just purchased a Leopard 4082 1600kv. Im in the process of reinforcing the hull. I picked up a few Prather 235's for future use and was wondering if a prop this large would be ok on the above set up. Boats purpose is for sporting, and speed passes, no organized racing. Thanks to all.
