3. Installation
LAGOON comes with two adapters that can be t into two major standard
n boxes which are widely used on most SUPs and a universal adapter for
kayaks and any small watercraft without standard n boxes.
3.1 Installation of LAGOON Motor
Before installing the LAGOON Motor to an SUP/kayak, etc., note that the
SUP/kayak, etc. must be strong enough to support the LAGOON Motor and
LAGOON Battery.
3.1.1 Installing with Standard Adapters
Two standard adapters are included in the LAGOON package: US fin box
adapter and inflatable SUP fin box adapter. These two standard adapters
can be used with the corresponding standard fin boxes in the market.
Choose a suitable one and follow the below steps to attach the LAGOON
Motor to the standard n box on the bottom of the SUP/kayak.
a. Installing with US n box adapter
1) Attach a US n box adapter onto the motor module base as shown in the
Figure 3-1. First align the adapter with the motor base; then insert the
adapter into the motor base until it is well attached.
21
Figure 3-1
2) Turn the SUP/kayak bottom up to attach the US n box adapter.
Step1: Place the back nut into the slot of the US n box, and move the nut to
the slot end near the tail of the SUP/kayak, etc.
Step2: Insert the adapter into the US n box in the direction of the arrow, and
slide it in until it fully enters;

15
Step3: Move the back nut in the slot to align it with the hole on the adapter,
then insert the screw into the hole and screw it tightly into the back nut.
Step4: The LAGOON motor is well attached to the US n box.

b. Installing with inatable SUP n box adapter
1) Attach an inatable SUP n box adapter onto the motor module base as
shown in Figure 3-3. First align the adapter with the motor base; then
insert the adapter into the motor base until it is well attached.

2) Turn the SUP/kayak bottom up to attach the inatable SUP n box.
Step1: Slide the standard adapter into the cave of the inatable SUP n box.
Step2: Insert the retaining clip into the place indicated in Figure 3-4 to x the
adapter.

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/kayak, etc.
Make sure the n box is clean before installation of the motor module.
3.1.2 Installing with LAGOON Universal Adapter
If the SUP/kayak, etc. has no n box or if both the two standard adapters
can’t t into the existing n mounting system, it’s suggested to use LAGOON
universal adapter to attach the LAGOON Motor. While mounting with the
LAGOON universal adapter, please follow the below steps.
1) Turn the SUP/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.

3) Fix the two ratchet straps: rst, penetrate the strap into the buckle; then,
repeat unfolding and folding the buckle to tense the strap. Fold the buckle
when the strap is tensed.
