Native has release an updated manual and maintenance instructions for the Propel drive. *Parts diagrams are attached to the second post below. Must be loved in to view/download.
Here are a few highlights:
Maintenance and Service
Much like the drive train of a bike, the Propel™ will require routine inspection and maintenance. Native Watercraft recommends maintenance every 6 months, or 75 days of use. The main purposes of these services are to ensure the internal gears of the unit remain properly lubricated and the covers remain tight and sealed. Failure to maintain these two key points may result in abnormal wearing of the gears and eventual failure of the unit. If you do not feel comfortable performing the prescribe maintenance, please contact your local dealer or Native Watercraft for assistance.
Cleaning of your Propel™
Spray off Propel™ with a water hose after each use, especially after use in saltwater. Do not use a high pressure car wash type sprayer.
Regular Maintenance Instructions
The covers are threaded into the Propel™ frame and use thread locker to ensure they do not come loose due to vibration and the rotational motion of the spindle. However, to ensure the proper function of the internal gears, it is important that the covers are completely threaded and flush to the frame. Visually inspect the top and bottom covers and, if necessary, use a spanner wrench to tighten. These covers should be inspected before every use. If the covers are loose, or have been removed, they should be reassembled using blue thread locker on the cap threads.
Lubricate Upper Gear Set
Your Propel™ utilizes gears that have been specifically designed for the most efficient and quiet transmission of your pedaling power. In order to ensure the same smooth function from the day you first purchased your boat, the gears will require a small amount of lubrication. Through the convenient grease port, you will be able to apply grease directly to the gears using an extended nozzle and Teflon grease. A lubrication kit can also be purchased from your local dealer. Remove grease port screw using a 3/16” hex wrench. Use an extended nose grease gun to reach gears. Inject 2 to 3 pumps of grease and replace grease port screw. Rotate crank arms slowly to apply grease throughout the gear assembly.
Lubricate Lower Gear Set
Remove the propeller by following the “Shear Pin Replacement” instructions on the facing page. Next, remove the cartridge using a spanner wrench with 3/16” pins.
Grease the Propeller Gear on the cartridge with 2 pumps from the grease gun. Grease the Lower Trans-mission Gear by inserting the extended nose grease gun and injecting 2 pumps onto the gear.
Return the cartridge to the main body. Be careful of gear conflict during the replacement of the housing. To avoid damage to gears, tighten by hand as much as possible, and if you feel resistance, stop and rotate the propeller spindle counterclockwise a few degrees .
