Torque refers to the rotational force or twisting force generated by an engine or motor. In the context of marine propulsion, torque determines the engine’s ability to rotate the propeller and move the boat through the water. A higher torque value means that the engine can exert more force to turn the propeller, resulting in improved acceleration, especially at lower speeds. It’s a critical factor in achieving efficient and responsive movement, especially during planning and acceleration phases. The common unit for torque is N*m (newton times meter) in metric and foot-pounds in imperial.
RPM stands for “Revolutions Per Minute.” In the context of marine propulsion, RPM refers to the number of complete rotations a boat’s engine or motor makes in one minute. It’s a measure of how fast the engine’s crankshaft is turning and is a critical factor in determining the speed and performance of the boat.
For marine propulsion, RPM is used to indicate how many times the propeller attached to the engine’s output shaft completes a full rotation in a minute. The RPM value is closely linked to the power and torque of the engine and influences the boat’s acceleration, top speed, and overall efficiency. Properly managing RPM is important for achieving optimal performance, fuel efficiency, and safe operation of the vessel.
Planing in boating refers to the phenomenon where a boat rises and travels on the surface of the water, rather than pushing through it. When a boat is planing, it essentially skims the water’s surface, supported by hydrodynamic forces, and achieves a higher speed and improved efficiency. Planing is typically achieved by increasing the boat’s speed and can happen faster when using our electric motors which have 30% more torque over fuel-based propulsion.
Outboard motors offer several advantages over inboard motors. They are typically more versatile and easier to maneuver, thanks to their external mounting on the transom of a boat, allowing for quicker directional changes and improved handling. Outboards are generally easier to access for maintenance and repair, as they can be easily lifted out of the water and removed. They also save valuable space within the boat, making them more suitable for smaller watercraft.
Electric outboard motors are versatile and can be used in a variety of water bodies, including both saltwater and freshwater environments. Electric outboards can perform well in saltwater conditions. However, one challenge in saltwater environments is the potential for corrosion. Regular maintenance, such as rinsing the motor with freshwater after each use and using anti-corrosion coatings, is essential to mitigate the effects of saltwater and ensure the longevity of the outboard. ACEL motors are equipped with N-nodes, which help prevent corrosion and enhance the longevity of the system in all environments.
