    Thanks Chris! Any idea why gear spins on the bushing, plus
    the bushing spins on the prop shaft?


    If you study the way the gearcase works, you’ll notice that one gear is always spinning in the opposite direction of the other one. Since the motor is engaged in forward gear 99% of the time, the reverse gear needs all the help it can get in the bearing department as the prop shaft is turning just as fast as it is but in the opposite direction. If the bushing was solid with the gear, either it or the shaft would soon wear out. This is why the bushing should spin freely in both parts, so they can share the load.
