Speedwatch
IMPELLER
The impeller is fixed on the watercraft, with
many options. We recommend you to fixe the
impeller at the prow, to avoid turbulences.
TRANSMITTER
The transmitter is inside the hull with the
magnetic sensor at 30 centimeters from the
impeller. The transmitter has to be fixed with
the "Dual Lock" to avoid any movement.
DISPLAY
The display can be placed everywhere in the
boat until 5 meters from the transmitter. A
plastic mounting support is joined to the display
and can be mounting on a flat area or the Velcro
strap can be used to wrap around the mast or
the leg. The transmitter has to be fixed to avoid
movement but the display can be moved while
it receives data.

IMPELLER, TRANSMITTER AND DISPLAY
ORIANTATION
To have a maximum distance between the
impeller and the transmitter, we recommend
you to put the transmitter in perpendicular
position to the impeller as shown in the picture
below. The distance between the transmitter
and the display is maximum if the display is
perpendicular to the transmitter.
Three mounting systems are included in the
SPEEDWATCH kit; a removable fin mount, a
large fin to be fixed on the keel back side and a
rudder mount.
The rudder mount has a black clip that rests on
the edge of the rudder, the strips of adhesive
are then wrapped around the clip and secures
it to the rudder. The impeller is screwed onto
the end.
The large blade fin to be fixed on the keel back
side can either be attached with VHB adhesive
tape or by screws. The cotter pin can be moved
to adjust the movement of the fin to allow the
impeller to be out of the water.
The white fin mount has a base plate that
is attached to the hull, either with the VHB
adhesive tape or by screws. The fin can then
be inserted and removed to store the impeller
while not in use. The impeller is screwed onto
the end.
