Back in 2009 it seemed there were fewer electric outboards available than fingers on one hand. Jump forward to 2023 and you might have to watch your step, for falling over them on every corner of boat show stands. The following are the key specification factors to look out for when making your choice:
Motor (kW) Manufacturers will also give you a horsepower (hp) equivalent to help. Motor ratings start at approximately 1kW (1.5hp) and head upwards. Manufacturers websites give information as to which size kW motor you'll require for your boat. Note the continuous rating (kW) to ensure the electric outboard will run all day if battery capacity allows. Peak motor (kW) ratings usually allow for a short sprint burst only. Battery capacity (Ah/kWh) The electric propulsion revolution is fuelled by the battery revolution, which means the benefits of modern batteries give us range and speed. Capacity is also directly related to cost. Consider the battery location. Smaller outboards tend to have their batteries integrated and removable, while larger outboards allow connection to a remote battery bank that would be installed in a suitable location on the boat.
Integrated usually means you have the option to remove it, allowing you to carry it separately back home for charging just as you would with a jerrycan. Remotely installed means batteries mounted in a locker or secured to the floor. Remote installation equals greater options for capacity, that means you can go longer and/or faster for longer.
The best choice is for a system approach using the manufacturer's own batteries resulting in a slick installation.
Sourcing your own batteries (third party) doesn't always pay off, but certainly can mean lower initial investment.
Voltage (V) Options start at 12V and run up to 48V. Expect outboards greater than 20kW to have higher voltages.
