right now i have that motor on a seagull extra 300s and and seagull edge 540... on the extra that motor is brand new and it turns great rpm on a 14x6 but on my edge my .75 has a 14x6 on it and it is turning about 9000 so what prop do you think will get me the most power out of this motor the book that came with the motor said 14x6 but i think something else would be better
