Hydrofoil mounting??
 

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

That is the correct location. As far back on the cavitation plate as
possible. This means make sure your holes are a couple inches from the rear
or more (you don't want to break the cavitation plate off due to the holes
being too close to the rear).

Do yourself a big favor and take it back and get your money back. Invest in
a set of smart tabs. Yes they are considerably more but you won't regret it.
Go to iboats and do a search on them and see for yourself And the raves
about them.http://www.iboats.com/cgi-bin/ubb/ultimatebb.cgi

I think I would try the foil first and see if it does not do what Rich is
looking for before spending $189.99 on the smart tabs. Problem w/ smart
tabs is they create a certain amount of drag and bow down all the time.
Speed will overcome it but there is always that push no matter what the trim
angle of the motor is.

The foil is adjusted by way of the trim angle of the drive.

He could buy either of the two hydrofoils I have in the garage for ten
bucks, plus shipping. Both were taken off so I could mount Smart Tabs...
Tabs work. Talk about adding drag...hydrofoil versus Smart Tabs????...no
comparison....I've owned 4 foils and have NONE mounted now......

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.

Wait a minute...Regarding that last paragraph...won't being able to plane at
lower speeds give you better fuel economy when you are driving in this
range? If you always drive at full spedd then there may be little
difference, but being able to plane at lower speeds gives you better fuel
economy at this speed.
