Took the boat out today to test and see if the hydrofoil makes any
difference. It is a new Tiger Shark VG Hydrofoil. Water conditions were
flat calm, very little wind. Boat was loaded with full fuel and two adults,
475# total.

Without the hydrofoil full throttle at 4400 rpms made 51 mph.
With the hydrofoil full throttle at 4400 rpms was 50 mph.

Cruising at 3200 rpms made 39 mph with or without the hydrofoil installed,
no difference at all.

With hydrofoil it did pop up on plane noticeably quicker and would stay on
plane at 2000 rpms. Without at 2000 rpms it would still plow with the bow
way high.

All considered I will keep it. It probably won't give me any better fuel
economy unless it would improve if I cruised at lower rpms. But for $22.00
it is worth it just to be able to plane at slower speeds.

Just picked up a hydrofoil for the boat. Directions say to mount it as
far
to the rear as possible on the cavitation plate. That would put it right
over, and mostly behind the prop. Does anyone have one of these mounted
on
an alpha 1 drive? Any tips?
Does anyone see a problem with mounting it that far back?

Thanks,
Rich
