mid 80's hull bow or stern lifting props?
Have 86 242 twin with alpha drives. Does this hull style bennefit more from a four blade stern lifter, or stick with the thre blades?

Re: mid 80's hull bow or stern lifting props?
Since you're running Alpha drives you may want to stick with three blade props. Four blades may be too much load for the Alpha to handle. "BOOM!!"
In swapping a Mirage prop for a Laser II of the same pitch I noticed my F206 doesn't need as much drive trim to carry the bow and at WOT the stern lifts. I can feel it in the seat of my pants, the stern gets a bit loose.
The difference between a Mirage and Laser II is the blade size (less area on the Laser), smaller outer diameter on the Laser II, and more blade rake (lifts the bow). I didn't gain speed, but it does come out of the hole easier.
