could my 45hp have a rev limiter in it? also off the stator there is two yellow wires and a blue wire and a blue/white wire. the blue and blue/white wire go to this 1"wide 4"long part then that goes to the switching box. what is is part? also the 2 yellow wire go to this 3x3 box that has 4 wire and ground on it. which 2wires go to the stator which are yellow and the other 2 wires which are red go to the rectifier.
