Ferman, that is a great offer that I will take you up on. That is one of the ones I want to try as it happens. When they first came out in like 1987 we used to rig them on Carolina Skiffs with the 90 hp motors (smaller case) You could surface them and keep the boat moving across some very shallow waters. I recall they were very good on holding plane slow and I see that they have a following now from the ski boat crowd. Must have some good bite. Someone on S&F has one for sale, but I want to try one first. I was thinking of calling Ken @ Prop Gods and see what he thinks as well. You solved one problem. Maybe we could get together and get Patrick to the water for some fishing/swimming/testing.
Based on preliminary testing and some initial numbers, I believe it will be hard to top the 21P Thunderbolt. It is just a great prop (Mirage Copy without the Vent holes). Maybe the ECO Enertia like Big Shrimpin posted the other day. He gained 3 or 4 MPH at the same RPM switching from a Mirage to a one pitch higher Enertia. I really really want to try a Maximus straight tube. IIRC it has the Tempest blade rake and shape and the diffuser ring cut off would help give less stern lift. How about a 21 Chopper? Lots of choices..
