    Hi woodie, l
    A little diagram may help!
    please note a car fuse holder will do,
    The speed 600 will pull 85 Amperes when stalled (stops spinning due to weed or string) max efficiency is 12A so a 20 Amp fuse would be a reasonable choice.

    Specification
    Nominal voltage 7.2 V
    Operating voltage range 3.6 … 8.4 V
    No-load rpm 18200 min–1
    No-load current drain 2 A
    Current drain at max. efficiency 12 A
    Current drain when stalled 85 A
    Max. efficiency without gearbox 69 %
    Length of case, excl. shaft 57 mm
    Diameter 35.8 mm
    Free shaft length 8.7 mm
    Shaft diameter 3.17 mm
    Weight 195 g

    Hope this helps

    Regards Roy

    Hi Woodie,
    Are having a bit of difficulty figuring out the fuse thing.

    The idea of the fuse is to prevent the wiring or other components from burning out.
    So we normally fit a fuse in the wiring circuit.
    I would normally have the positive wire coming from the Battery going to the main switch then passing through the fuse then on to the speed controller.

    If you picture it as the boat has two circuits,
    One is the radio control circuit
    Two is the power that will make it all work.(Dirty)
    The two circuits are linked,

    I hope this helps.

    Martin555.
    If it looks right it probably is.

    Between the battery and ESC.
    Try to keep the dirty wiring away from the clean.
    Dirty wiring is considered the motor, Battery etc. Make sure you have the motor suppressed

    Hi Woodie,
    Welcome, always like to hear of newcomers to this wonderful hobby. Don't be surprised if it becomes rather obsessive.
    The Sea Commander is a good boat to own, whether it's your mother or yourself. It was one of the early boats that I built and after a couple of improvements she turned out to be a really nice boat. If anything she can go a bit too fast for me, but there. I'm an old fogey.

    Cheers, Nerys
