YOUR BOAT
SPEEDOMETERS:
There are two speedometers mounted on the dashboard of your
boat. They are calibrated by Correct Craft at 36 mph. They can be adjusted by turning
the knob at the bottom
of
the face of the speedometer. The speedometers are two
wholly
separate
systems. One
is
a back-up
in
the event that the other becomes
obstructed. (Consistent speed is critical to the tournament skier.)
On
each side of the transom below the water line, you will find a tube with a fitting and
a rubber hose leading from
it.
This
is
called a "pitot tube," "impact tube"
or
"pick-up tube."
Let's call it a "pick-up" tube for the sake of discussion. The pick-up tube allows a small
amount of water to be driven to a certain point
in
the system
as
the boat moves forward.
That point
in
the system
is
called a "stabilizer tube." It
is
a vertically mounted brass tube
at the stern. (You can't see this tube since it
is
mounted behind the gas tank.)
What happens
is
that the water
in
this tube compresses the air
in
the hose connecting
to the instruments and it becomes, literally, a pressure gauge.
(Remember,
there
are
two
separate
speedometer
systems
In
your
boat.)
NOTE: When trailering your boat, it
is
a good idea to place your pick-up tubes
in
the
stored position, that
is,
turned to the side. This
is
recommended to avoid collection of
road debris such
as
mud, oils and any other matter than can become lodged
in
the tube,
thus adversely effecting the efficiency of your unit. To achieve this, press down firmly at
the end of the tube (it
is
spring-loaded) and turn upward
in
either direction.
