I just got my brand new Yamaha prop wrench from an eBayer at a nice
discount. It's time for the painful (expensive) search for the perfect
prop. I know I need to drop the pitch by at least two inches. A cup
may be in order to improve the hole shot. The stock aluminum prop
doesn't "bite" quick enough and lacks in the top end by 750 rpm's.

The variables are endless - diameter, pitch, cup, venting, etc. so this
time I'm trying something new. I have a good idea of what the diameter
and pitch should be. I'll get a SS prop in that size and let the prop
shop tweak it for me. The one thing I know for sure is the F90 is best
suited for a three-blade prop rather than a four.

Once that is settled, I'm going to look further into the value of a
narrow jack plate. So far it looks like the hydraulic plates aren't
much more $$ than a manual.
