My intent is to set it at lets say 7000 rpm "It is varable so not sure what to set it at will have to mess with it" To kick in and use a clutch lever with a switch in it to kick it in. Once I am off the line I dont need the clutch and the box will no work unless the clutch is pulled, that way I can hold the throttle wide open and not let the motor just be screamin wide open on the line. with one set rpm off the line it may help my 60ft. I am running 16 41 gearing now and I set the paddles on fire, may need to also go to more paddles but will see if the box helps
