3. Installation
VAQUITA comes with two adapters that can be t into two major standard n
boxes which are widely used on most SUP boards and a universal adapter
for kayaks and any small watercraft without standard n boxes.
3.1 Installation of VAQUITA Motor
Before installing the VAQUITA Motor to a SUP board/kayak, etc., note that
the SUP board/kayak, etc. must be strong enough to support the VAQUITA
Motor and VAQUITA Battery.
3.1.1 Installing with Standard Adapters
Two standard adapters are available in the package: US fin box adapter
and inflatable SUP fin box adapter. These two standard adapters have
compatible fin boxes. Choose one and follow the below steps to attach
VAQUITA Motor to the standard n box.
a. Installing with US n box adapter
1) Attach the US n box adapter onto the motor base (Figure 3-1). First align
the adapter with the motor base; then insert the adapter into the motor
base until it is well attached.

Figure 3-1
2) Turn the SUP board/kayak bottom up to attach the US n box adapter.
① Place the back nut into the n box and move the nut to the end close
to the tail of the SUP board/kayak, etc.
② Insert the adapter into the n box in the direction of arrow, and slide it
in until it fully enters;

Do not force the adapter into the n box. If the adapter can’t t into the
n box properly, slide it out and check if the installing direction is correct.
The propeller should face the tail of the SUP board/kayak, etc.
Make sure the n box is clean before installing the motor.
3.1.2 Installing with VAQUITA Universal Adapter
If the SUP board/kayak, etc. has no fin box or if both the two standard
adapters can’t t into the existing n mounting system, it’s suggested to use
VAQUITA universal adapter to attach VAQUITA Motor.
①Turn the SUP board/kayak, etc. bottom up.
② Penetrate the two ratchet straps through the side opening of the universal
adapter and attach the universal adapter onto the relatively at part on
the bottom.
