Hey Paul,
Do you have a suggestion for a good fixed prop for a 220HP cruiser?

Not yet. I need to look into that carefully. One advantage of having a
turbo is; if we have too much pitch we can always up the boost a bit to
get more torque and HP at what ever RPM turns out to be max.
It gives us a bit more leeway in choosing a fixed pitch prop.

A variable pitch prop on the other hand should buy more miles per gallon 
as you can slow the RPM with more pitch to cut engine friction and reduce 
the cruise fuel consumption and improve the BSFC.
