(As an aside, we designed a custom prop for one of the mid-90's AC
syndicates to use in side-by-side testing. They wanted to match drag figures
as closely as possible, so they were looking to add some 30-35 lbs thrust to
one hull. The existing trolling motor props lost all of their thrust as boat
speed increased, so we did a prop with much higher pitch to get a better
speed-rpm-pitch match where they needed to be. Who knows, there might be a
nice market for replacement props with higher pitch for small boats.)

YES! There is definitely a small but viable market! There are a BUNCH of us
with 21' SeaPearl sailboats who use various electric motors as auxiliaries. I
am almost positive I could get significantly more speed with a higher-pitched
prop, but have found nobody who makes one. Any chance of getting one made for a
MinnKota EX42 for a trial?
