Figure 4.4 - Outboard Dimensional Drawing Figure 4.
Figure 4.6 - Outboard Dimensional Drawing 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.
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.
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.
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.
Figure 4.10 – Tilt Lock Engaged 4.2.7 Manual Tilt/Trim Release If the power tilt/trim ceases to respond to input from the tilt/trim button on the Throttle, there is a manual release valve on the bottom of the tilt/trim unit that can be used to release the pressure in the tilt/trim unit and allow for manual adjustment of the Outboard position. 1.
Figure 4.12– Loosening the Release Valve Fastener If the Outboard is tilted up when the release valve fastener is loosened, the Outboard will tilt downward under its own weight. Keep clear of the Outboard to avoid injury due to pinching in the mechanism or being struck by the Outboard. 3. To raise the Outboard, lift by pulling up on the end of the anti-ventilation plate. Figure 4.13 – Lifting the Outboard via the Anti-Ventilation Plate 4. Use the tilt lock (see Section 4.2.
Lifting the Outboard manually presents the risk of injury while holding the Outboard and simultaneously engaging the tilt lock. It is recommended to do this with two people. 5. Use a flat head screwdriver to re-tighten the fastener on the bottom side of the tilt/trim until snug by turning the screw clockwise. The Outboard will remain in position when the fastener is tightened. 4.2.
4.3 Battery Pack 4.3.1 Overview The Pure Watercraft Battery Pack is a modular and portable lithium-ion power source for use within the Pure Outboard system either as an individual Battery Pack or connected with up to 10 other Battery Packs. Figure 4.15 – Battery Pack Features 1. Strap guide (x4) 2. Lifting handles 3. Receptacles (x2) for Cable connection ● Do not attempt to open or disassemble the Battery Pack. ● Do not attempt to repair the Battery Pack.
● Do not operate the system with a damaged Battery Pack. If an issue is suspected with the Battery Pack, stop using the system immediately. ● Do not attempt to charge a damaged Battery Pack. ● If a Battery Pack is visibly damaged, avoid any contact with water. ● Be sure the system is powered Off prior to connecting or disconnecting a Battery Pack. ● Do not attempt to use a Battery Pack as a power source for anything other than the Pure Outboard system.
4.3.3 Battery Pack State of Health State of health is a measure of the condition of the Battery Pack and its performance relative to a new Battery Pack. It takes into account the maximum energy capacity available in addition to other factors. The state of health of the Battery Pack, like all lithium-ion batteries, will gradually degrade over time as a result of use. State of health is shown as a percentage value, with 100% representing the state of health of a fresh Battery Pack.

Throttle position – indicates if the current position of the throttle is in Forward, Neutral, or Reverse. 9. Efficiency gauge – shows the watt-hours per mile (Wh/mi) consumed at the current throttle position. The lower the Wh/mi value, the more efficiently the system is operating. (See Section 5.3) 10. Number of batteries connected.
Low battery state of charge When the State of Charge of the Battery Pack(s) is below 10%, the state of charge display bar will turn yellow and the battery icon will turn yellow. In a multi-battery system, if one Battery Pack’s State of Charge is below 10%, then the battery icon corresponding to that Battery Pack will be displayed in yellow. Figure 4.
Power derating due to low battery state of charge Depending on the power output of the Outboard at the time when the low Battery state is reached, the system may automatically reduce power output to preserve the remaining energy available and to maximize remaining boating range. This will cause the boat to slow down. Note that given the nature of powering vehicles and boats with electricity, they can generally be powered for a greater distance at slow speeds than they can at high speeds.
Figure 4.35 – Temporary Over Temperature Notification Figure 4.36 – Persisting Over Temperature Notification System reset required Sometimes for reasons of safety or system error, the Pure Outboard system issues a fault warning that must be reset for the system to resume operation. If this is necessary, the Reset notification will be shown on the display. Push the button as indicated on the display to reset the system.
Pure Watercraft is frequently updating its software and firmware to address and minimize the need for system resets, and the best way to minimize the occurrence of system resets is to ensure the latest software and firmware updates from Pure Watercraft are uploaded from the Mobile App to the Pure Outboard system (see Section 7.9). Cables disconnected If one or more Cables are not properly connected, the Throttle display will show a warning to check the connections.
Start-in-gear protection If the Throttle handle is not in the neutral position when attempting to Start the system, the Throttle display shows a message indicating that the handle must return to neutral to begin boating. Figure 4.
Tilt/Trim timeout The tilt/trim timeout notification will appear if the tilt/trim temporarily stops after 45 seconds of continuous actuation, to prevent it from being damaged. After 10 seconds, the notification will disappear and tilt/trim operation can resume. Figure 4.41 – Tilt/Trim Timeout Notification 4.5.
Figure 4.42 – Throttle Display when Charging If the temperature of a Battery Pack is too high to safely charge, the Throttle display will show a warning icon. Move the Battery Pack to a cooler location or out of direct sunlight to reduce the Battery Pack temperature and resume charging. Figure 4.
4.6 Cables This section outlines the Cables necessary to connect the Pure Outboard system. Section 10 explains how to configure the Pure Outboard system and connect the Cables properly. ● Only use the Cables provided by Pure Watercraft for connecting Pure Outboard system components. ● Do not use the Cables provided by Pure Watercraft for any purpose other than to connect components of the Pure Outboard system as instructed in this User Guide.
Auxiliary Power Output Cable See Section 4.5.1 Charger AC Power Cables See Section 4.4.2 4.6.2 Cables Not Supplied by Pure Watercraft ● Steering cable – to connect the Pure Outboard system to a vessel’s steering. The Outboard is designed to the standards established by the American Boating and Yacht Council for outboard-mounted steering systems. ● Extension cords – to extend range between the end of the Charger AC Power Cable and the AC power outlet.
5 OUTBOARD OPERATION Operation of a boat powered by the Pure Outboard should always be done on a body of water that is authorized for power boating. Even though some pictures shown in this section are of the boat on dry land, the steps contained in this Operation section are intended to be performed while the boat is in the water. 5.1 Before Startup 1. Confirm that the steering lock on the Outboard motor is unlocked (see Section 4.2.8).
Figure 5.2 Tilt Lock in the Locked Position 3. Check the Outboard, propeller, Throttle, Battery Pack, and Cables for any visible damage. In case of visible damage, do not power on the system and do not attempt to charge the Battery Pack. 4. Check that all Cables are securely connected to the Battery Pack and Outboard. 5.
3. Check that the emergency stop lanyard is connected to the operator’s wrist, leg or personal floatation device (while being worn). 4. To turn on the system, push the Power button on the Throttle. 5. The Throttle display screen will illuminate. 6. If any system components are not ready for operation, a message will display on the screen (see Section 4.5.7). Resolve any such warnings before proceeding. 7.
● If starting the system in temperatures below 32ºF (0ºC), the system will not start for a few minutes while the Battery Pack heats to an acceptable operating temperature. The Throttle screen will show a message indicating the reason for the delayed start. ● Power is limited when in reverse to prevent accidental or excessive power when reversing, which could be dangerous and cause certain boat hulls to be swamped. 5.
The system will limit the power that is available to the motor when the Battery Pack reaches approximately 20% state of charge. The top speed at which the boat can travel will be limited as a result. This power derating is done to ensure the system retains enough energy to allow greater range of travel at a lower speed in order to provide an operator with enough reserve power to return safely to shore and to prevent an operator from being stranded away from a safe mooring without power.
Figure 5.4 – Over Temperature Derating Notification Full power operation will be possible when the system temperatures return to an acceptable level. The fastest way to reduce system temperatures is to pause operation of the system. Confirm that the Outboard motor is tilted down and propeller is in the water, that the Battery Pack(s) has (have) sufficient airflow around them, and that the Battery Pack(s) is (are) not in direct sunlight.
6 CHARGING The Battery Packs can be charged while on the boat, and can also be charged when removed from the boat in cases where charging at the boat is not feasible. The Charger can rest on a flat surface during charging (such as the floor, a dock, or a boat deck) or can be wall mounted (see Section 10.8). ● All wiring and circuit breakers need to be installed by a qualified electrician and in accordance with local building codes to prevent power overload conditions or accidental sparking and/or fire.
Figure 6.1 – Charging a One-Battery Pack System on a Boat 3. Ensure the Throttle Cable remains connected to the Battery Pack. 6.1.2 Connecting a System with Two or More Battery Packs to the Charger 1. Identify the Battery Pack which is connected to the Outboard. 2. On that Battery Pack, unplug the Power Data Cable that is connected to the Outboard. 3. Connect the Power Data Cable from the Charger to the Battery Pack, in place of where the Outboard was previously connected. Figure 6.
6.1.3 Charging Operation 1. Plug the appropriate Charger AC Power Cable to the intended power outlet. The Charger is compatible with the source power outlet types listed in Section 4.4.2. 2. To begin charging, press the Power button on the Charger. The light on the Charger will illuminate and the Charger will begin charging the connected Battery Pack(s). The emergency stop must be attached to the Throttle. (see Section 4.5.2). 3.
6.3 Charging Schedule If operating the system at least one time per month: Charge the Battery Pack after each use. You can leave the Battery Pack charging when not in use for up to one month continuously. Do not charge continuously for more than one month to prevent harm to the system’s memory. If not operating the system for one month or more (includes storage): 1.
*When charging on 110V–120V outlets, it is recommended to simultaneously charge a maximum of two Battery Packs per Charger in order to charge fully overnight. The same charge times could be expected to recharge the corresponding number of Battery Packs from 20% to 70%. As a basic rule of thumb, double these expected charge times if charging the corresponding number of Battery Packs from 0% back to full 100% charge.
7 MOBILE APP The Pure Watercraft Mobile Application (Mobile App) shows information about the Outboard system, trip history, and usage statistics. It also allows for establishing system Settings, installing updates, and contacting Pure Watercraft for assistance. The Mobile App pairs with the Pure Outboard system via a Bluetooth connection. 7.
7.3 Reconnecting the Mobile App with the Outboard System Once paired, the Mobile App should reconnect to the system automatically when in Bluetooth range.

8 TRAILERING ● Ensure that there is no risk of the Outboard coming into contact with the ground before or during the trip. ● Ensure that the steering lock and the tilt lock are both securely engaged (see Sections 4.2.6 and 4.2.8). ● Ensure that the Throttle is in the neutral position for transport so it remains locked in place and not subject to rattling or dislocation resulting from significant bumps or swerves that the trailer may encounter.
Figure 8.1 – Outboard Supported by a Transom Saver 8.2 System Security During Transport The Pure Outboard system does not have a traditional key like some gas engines. To prevent someone from starting the system when it is parked on a trailer unattended, remove the emergency stop lanyard from the Throttle and keep it stored in a safe place away from the boat.
9 STORAGE 9.1 Storing the Batteries & Charger ● Store the batteries in a dry and cool place. ● Do not immerse the Battery Pack in water or allow it to get and stay wet. ● Do not store the Battery Pack in direct sunlight or near sources of heat, such as a fireplace or heater. ● Do not apply direct heat to the Battery Pack or place it in contact with an open flame.
Figure 9.1 – Tilt Lock in the Locked Position ● If storing the Outboard indoors or on land, it is recommended to store the Outboard in the shade and out of direct sunlight when possible, to ensure the motor is cool when ready for use so that the motor isn’t immediately subjected to power derating due to temperature.
10 INSTALLATION It will take approximately one hour to install the Pure Outboard system on a boat after the previous motor and throttle have been removed. The installation can be completed with two people, or by one person if a crane is available to place and stabilize the motor during mounting. Installing the Pure Outboard system on a boat must be done when the boat is on a trailer on a flat surface and in a dry place.
10.1.2 Selecting the Location for Mounting the Throttle The Throttle can be mounted directly to a horizontal surface on the boat using the mounting points on the bottom of the Throttle, or on a vertical surface on the boat using the Throttle mounting bracket (see Figure 10.18 & Figure 10.19).
● If crossing the Cables over a fiberglass bulkhead, use a grommet to prevent damage to the Cables over time. ● Do not kink the Cables. ● Do not route the Cables over components that may get hot. 1. Run the small end of the Throttle Cable plug from the Battery Pack up to the helm through the established path that carries the boat’s steering cable (typically up the starboard side under the gunwales). Do not connect the Cable to the Battery Pack. 2.

When the Pure Outboard system is powered off, the accessory switch activates a relay which provides power from the 12 volt battery to the fuse panel. When the Pure Outboard system is powered on, the same relay is opened, which allows the Pure Outboard system to charge the 12 volt battery. When the Pure Outboard system is powered on, the fuse panel can draw from the Pure Outboard system and the 12 volt battery in the event of a large current draw.

11 SYSTEM CARE ● If any component becomes mechanically damaged, immediately stop using the system and contact Pure Watercraft. ● Always keep the high-voltage Battery Packs clean and free from dirt. After each use: ● Rinse the Outboard with fresh water, especially after operation in salt or brackish water. ● To clean the Pure Outboard motor surfaces, use a boat soap which is approved for marine use in your jurisdiction. ● Check the propeller for damage or tangled weeds.
○ If only the outer black cable insulation is damaged but the internal cables are not visible, correct the source of the chafe by smoothing out the edge, adding a rubber or foam bumper, wrapping the cable in anti-chafe tape, etc. ○ If the chafe damage has penetrated through the outer black insulation and the interior cables are visible, the cable must be replaced.
● Check the status of the anode periodically, especially if operating in salt water. ● For best corrosion protection, replace the anode before it becomes fully corroded. ● Replacing the anode: ○ Use ½” ratchet wrench to remove the anode bolt and accompanying washer. ○ Install new identical marine anode with alignment peg centered in slot in anode recess. Ensure anode is seated flush in the recessed flat section of housing and does not rock ○ Reinstall anode bolt and washer, torque to 12 Nm.
