Thinking of making a pedal-powered boat, stainless shafts, suggestions
for bearing materiel please. And sources for suitable plastic mitre
gears in qty=2 pairs, smallparts has some but they may be too small.


Most pedal boats use Delrin for the bushings, usually they are 1-1.5"
wide They are set up so they don't run below the waterline as well.
