So you have installed your sparkling brand new Torqeedo Ultralight 403 electric outboard. How do you maintain it? Maintenance is always good practice for protecting and getting the most longevity from your investment. Being an electric motor the Ultralight 403 has very low maintenance.
Cleaning off your Motor:
After a day out on the water its always good to rinse off your motor. Remove dirt and mud that may have accumulated. Also remove any weeds that may have wrapped in the prop. This is always a good time to inspect the propeller for any foreign objects such as fishing line.
For use in saltwater its good to rinse off with soap and a brush off the motor thoroughly. Just about the entire motor system is aluminum which will discolor and pit over time. Using a soap such as simple green a brush and some water clean off the entire system after each use.
Keeping Connections Clean:
Over time power and data connections become dirty. The gold plated electrodes are easy to clean by spraying them down with WD-40. Drain the residual out the plug. Then insert each end into the battery. Then pull out and reinsert them.
Personally I like to cap my connectors after use. Using Screw Protector and Pipe End Caps on the connectors keeps out dirt and sand that could cause a connection to fail. They also protect against damage to the pins in the connectors. Bent connection pins will result in the cable failing.
Cleaning the Throttle Controller:
Over time salt, dirt buildup, and grime can bind down your throttle handle. Its good practice to rinse the throttle controller after use but often this is forgotten. If it becomes bound up and doesn’t seem to stop propulsion simply fill up a tub with about 3/4″ of warm water. Set the throttle int he water on its side with the throttle handle. Let soak fr a good 20 minutes. This should dissolve salt from the unit.
