2 SAFETY
2.1 General Safety Information
● Use the Pure Outboard electric propulsion system only in accordance with the instructions
provided in this User Guide, as well as all applicable local laws and regulations.
● Only allow the Pure Outboard electric propulsion system to be installed, operated, cared
for, and repaired by others who have also read and understood this User Guide. Ensure
that this guide is included with this product if the product is ever given or sold to another
user.
● Only allow the Pure Outboard electric propulsion system to be installed on a safe, well
maintained, seaworthy boat rated to accept a motor system that weighs 300 pounds or
more and a motor system that generates 25kW (equivalent to 50 horsepower) or more of
propeller shaft output. To operate the Pure Outboard electric propulsion system on a boat
that is rated for less than 25kW (equivalent to 50 horsepower) of propeller shaft output
and/or in an area that restricts power output, contact Pure Watercraft in advance to
explore the possibility of implementing a “factory setting” that limits the propeller shaft
output to comply with the manufacturer’s rating of your hull and/or local jurisdiction
licensing or operating regulations.
● Anyone who might be near the Pure Outboard electric propulsion system while any
component of it is in operation must be informed of the potential dangers and instructed on
how to avoid injury during its use.
2.2 Pure Outboard Safety Instructions
● Only use the Cables provided by Pure Watercraft for connecting Pure Outboard system
components.
● Before every trip, check all system components (Outboard, Battery Pack, Throttle, and
Cables) for possible damage. In case of damage, do not touch any exposed parts or start
the motor, and contact Pure Watercraft immediately.
● Prior to every trip, check the emergency stop Lanyard to ensure it is properly connected to
the Throttle and there is no damage to the lanyard. Secure the emergency stop Lanyard
somewhere on you (commonly worn on the wrist or around your leg) or attach it to the
personal floatation device you are wearing. The purpose of the emergency stop is to turn
off the motor in the case the operator moves out of operating range from the Throttle, such
as an accidental fall. In case of other emergencies while under power, pull the lanyard to
stop the motor.
● Do not disconnect the Cables from any part of the system (Battery Pack, Outboard,
Throttle, or Charger) unless the system is powered Off.
● Do not open any part of the Outboard, Battery Pack, Throttle, or Charger. Components
may only be opened by persons authorized by Pure Watercraft.
● Do not sit or stand on the Battery Pack. Do not place heavy objects on top of the Battery
Pack.
8

● Do not operate, transport, or store the Battery Pack on its sides or upside down.
● Keep the Battery Pack away from external heat sources and respect safety instructions
affixed to the Battery Pack.
● Only run the Outboard when the propeller is underwater.
● Ensure that no person’s limbs are in the way of the Outboard before activating the tilt/trim
to avoid injury.
● If the boat is moved in the water by external means other than the Pure Outboard (towing,
sailing, running with another motor), raise the Outboard out of the water to prevent
collision and damage.
2.3 General Safety Instructions for Boat Operation
The boat operator should be knowledgeable on how to operate the boat, Outboard, and
accessories correctly.
● Familiarize yourself and others on board with the control elements of the Pure Outboard
system, especially how to stop the motor quickly with the emergency stop if necessary in
accordance with this User Guide (see Section 4.5.2).
● Only individuals who have been fully instructed on operating procedures in accordance
with this User Guide, and local boating regulations, should operate the system.
● The boat operator is responsible for the safety of people on board and for any watercraft
and people near the boat. Respect the rules of safe boating and follow the laws and
regulations within the area in which the boat is operating.
● Pay special attention to your surroundings, particularly people and objects in the water.
● Check that all necessary boat safety equipment is on board prior to boating.
Never enter the water or swim in a marina or near docks where boats are connected to
electrical power. Faulty wiring can cause stray electrical current to enter the water, which can
shock a person in the water and cause drowning.
If someone in the water appears to be shocked, first turn off the power at the dock. Throw a
life preserver to the victim. Do not enter the water, as the risk of shock may still be present.
9

● When the boat is near people and swimmers in the water, be sure the motor is
completely shut off to avoid accidental engagement of the propeller. A spinning propeller
can cause severe injury.
● Unlike conventional outboards, the Pure Outboard motor is near silent, particularly at low
speeds. Take extra caution when starting the system, when boating around other boats,
and while docking, as you and those around you may not hear the motor while it is
operating.
● Never sit or stand in areas of the boat that are not intended for passengers while the
motor is on or while the boat is in motion (seatbacks, transom, or sides of the boat). The
Pure Outboard system is powerful enough to accelerate a vessel so quickly that
passengers may be thrown from the boat and seriously injured.
● Do not operate the Pure Outboard system if it has experienced damage as a result of a
collision or other form of impact.
● Do not operate the Pure Outboard system if it shows signs of visible damage. Exposed
electronics may pose the risk of electrical shock.
● Limit boat speed when operating in shallow or unknown areas where obstacles may hit
the Outboard.
● Do not exceed the boat manufacturer’s instruction on maximum motor horsepower,
loading limits, and capacity limits.
2.4 Liability Warning
Pure Watercraft does not take any responsibility or assume any liability for improper use of the
Pure Outboard system. The user is obligated to obey and follow all of the above safety
guidelines, as well as any applicable local rules or regulations.
Pure Watercraft shall not be held responsible for damages or injury for any reason, including
damages or injuries resulting from improper use or failure to follow proper safety measures.

4.2 Outboard
4.2.1 Overview
The Outboard outputs up to 25 kW of continuous power, equivalent to the propulsive power of a
20-50 HP gas outboard. It includes power tilt/trim to raise and lower the Outboard. Given its low
placement to the waterline, it is designed to be splashed and momentarily submerged. It is
designed to operate in fresh and saltwater environments.
On some boats sold by Pure Watercraft, the Outboard’s maximum power output may be limited
to the maximum engine power allowed for that vessel model. The maximum power output value
is displayed on the Throttle display as shown in Section 4.5.6. For more information on setting
and modifying power output limits, contact Pure Watercraft.

4.2.2 Outboard Energy Throughput
Energy throughput is the amount of cumulative energy that has run through the Outboard,
measured in kilowatt-hours (kWh). It is a way to measure system lifetime usage which accounts
for the system power output, measured in kilowatts (kW), in addition to hours of operation. It is
similar to an odometer in a car, but appropriate for outboard motors which operate on different
vessel types.
The cumulative energy throughput of the Outboard can be viewed in the Pure Watercraft Mobile
App.
4.2.3 Power Tilt/Trim
The Outboard includes an electronic tilt/trim mechanism which raises or lowers the Outboard to
adjust its angle relative to the boat. This is controlled via the tilt/trim button on the Throttle
handle.
17

1. Push to tilt/trim motor up.
2. Push to tilt/trim motor
down.
Figure 4.7 – Tilt/Trim Button on the Throttle
Tilt and trim are both controlled by the same component on the Outboard, but they have
different functions. Tilting refers to the operator making large adjustments to the Outboard angle
by raising the Outboard all or most of the way up and out of the water, whereas trimming
involves the operator making very small adjustments to the Outboard angle while the boat is in
motion.
4.2.4 Tilting
Tilting is generally performed when the boat is stationary in preparation for trailering or
launching, or when operating at slow speeds in shallow water. The tilt range of the Outboard is
14.6° to 67.1° relative to a vertical plane. The Outboard cannot be raised into the tilt range while
running at high power, but it can be lowered down into the trim range.
●To tilt the Outboard, put the Throttle in the neutral position and press the Power button
until the Start Screen is shown.
●Verify that the Outboard is clear of any obstructions or people.
●Push the trim up or down button on the Throttle until the Outboard is tilted to the desired
position, then release the button.
Tilting the Outboard from the fully down position to the fully up position should only take
approximately 15 seconds. If the tilt/trim is laboring or taking longer than that, stop tilting and
examine the Outboard for anything inhibiting the tilt operation.
4.2.5 Trimming
Trim refers to the running angle of the boat as it moves through the water. When the trim of the
Outboard is adjusted, the bow (the front of the boat) will be either raised or lowered. The trim
range of the Outboard is -2.7° to 14.6° relative to a vertical plane.
18

Instructions for proper trim:
● The Outboard operates most efficiently when the tail cone is operating parallel to the
horizon.
● The degree angle shown on the Throttle display (see Figure 4.8) refers to the Outboard’s
angle relative to its perpendicular down position.
● For planing hulls, adjusting the trim can improve the efficiency of operation when on
plane.
● Planing hulls operating on-plane with an improper trim angle may experience
“porpoising,” in which the bow bounces heavily on the surface of the water. To remedy
this, trim the Outboard down until the bouncing stops.
Improper trim may result in a pull on the steering wheel and loss of control.
Trimming the Outboard:
●To trim the Outboard down (bring it closer to the boat), press the trim button down.
●To trim the Outboard up (bring it away from the boat), press the trim button up.
●The trim angle is visible on the Throttle display when the trim button is actuated.
Figure 4.8 – Tilt/Trim Position on the Throttle Display
19

Figure 4.8 shows the Outboard trimmed one degree (clockwise on the diagram) from
perpendicular. The full range of tilt/trim motion for the Outboard is -2.7° to 67.1°.
The tilt/trim is not meant to be operated continuously for longer than 45 seconds. Safety
features are incorporated that will cause the tilt/trim to temporarily stop operating after 45
seconds to prevent it from being damaged. After waiting 10 seconds, the tilt/trim operation
can resume.
4.2.6 Tilt Lock
Engage the tilt lock to lock the Outboard in the tilted up position during storage and transport.
Using the lock reduces the pressure on the hydraulic tilt/trim assembly.
When trailering, be sure to use a transom saver to support the Outboard (see Section 8 for
trailering instructions). Do not rely on the tilt/trim or the tilt lock alone to keep the Outboard up
while trailering. They are not intended to support the Outboard while trailering.
To engage the tilt lock:
1. Raise the Outboard to the fully tilted up position.
2. Flip the tilt lock into the locked position.
Figure 4.9 – Tilt Lock in the Ready-to-Lock Position
3. Lower the Outboard for approximately 4 seconds until it rests on the tilt lock.
