rc model boat gearbox
The only 1:1 boats i am aware of that had multi-speed transmissions are some of the top fuel drag boats that used the chevy power glide 2-speed transmission. 1st gear got the boat out of the hole where higher engine speed and lower prop speed is necessary, and 2nd gear took over once the boat was on plane and headed for top speed....
