Great video. Are you not afraid of water getting into the carb? Maybe add a small shield/cowl.

Yeah Paul, some type of small cover should be added. When I get to more aggressive props which are harder to lunch having the carb dry will only help get it up on pipe.

I would also think that currently the carb would be in very turbulent air

Got some test time in Saturday with the TT boat. Switched over to the blue head 91 VAC and ran a couple tanks through to break the motor in. She is still rich in these videos. New turnfin helped.

Looking good, that new fin's working much better.
Any idea what SAW speed is?

Hey Terry, the new fin is working much better but I think I still need a little steeper leading edge to reduce more lift. Or I need to modify the lift characteristics of the sponsons. It turns exceptionally well almost too good. I am thinking the next design will have a shorter chord length in addition to the steeper leading edge.
I think the speeds here are in the low 70's with the 2719. I did not lean the needle, but no where near the speeds I need to chase Martin down. I need to be in the mid 90's.

Sorry TK, I realized I never responded to your question. The lay-up design is quasi-isotropic, consisting of three layers of carbon fiber on each side of a Divinycell H100 foam core center. So it's 1/4" foam with 0.035" 3-layer carbon on the sides.
I am using Loctite Hysol HP-120 toughened epoxy to bond all the panels together.
