In the performance evaluation system of electric outboard motors, range and speed are the key dimensions to measure whether they are excellent. They not only determine the navigation range and efficiency of the boat but also profoundly affect the user experience. However, due to the diversity of application scenarios and boat types, it is difficult to define "excellence" with a single standard; instead, the analysis needs to be carried out in combination with different usage requirements.

Recreational Fishing Scenario: Long Range + Medium-Low Speed Adaptation

For recreational fishing enthusiasts, who usually stay on the water for a long time, range is more demanding, while speed does not need to be too high. Taking the common 4-6m fishing boats as an example, an excellent electric outboard motor should have the following performance in this scenario:

Range: Equipped with a large-capacity lithium battery, such as lithium iron phosphate batteries or ternary lithium batteries with high energy density, with a battery capacity of 10-20 kWh. At the economic speed, the continuous navigation time can stably reach 6-8 hours. For instance, the Bestwin 1.2kW (3HP) electric outboard motor is equipped with a 1440Wh large integrated lithium battery. Under different power outputs, the continuous navigation time ranges from 1 hour 12 minutes to 2 hours 24 minutes. When matched with a larger-capacity battery for a full-day fishing scenario, it can meet the needs of most recreational fishing activities.

Speed: An economic speed of 5-10 knots (approximately 9.26-18.52 km/h) is more appropriate. This speed not only allows anglers to quickly reach fishing spots but also move slowly in the water area to find fish schools, while keeping energy consumption low. For example, when a Sealander boat is equipped with a 5HP electric outboard motor, its maximum speed can reach 7 km/h. At this speed, the battery can support 8 hours of navigation or a travel distance of 30 km, perfectly matching the mobility needs of recreational fishing.

Water Sports Scenario: High Speed + Appropriate Range

In the field of water sports (such as jet skis and small racing boats), the core demand is excitement and speed, so the requirement for range is relatively lower (but it still needs to meet the duration of a single sports session). Taking the common 3-5m water sports boats as an example:

Speed: An excellent electric outboard motor should have strong power, with a maximum speed easily exceeding 30 knots (approximately 55.56 km/h). For example, the WAVE 70 electric outboard motor from Qingbo Exploration, when mounted on a 4.98m electric bass boat, can reach a maximum speed of 60 km/h. This fully meets the extreme speed pursuit of water sports and brings a thrilling experience to players.

Range: Considering that each water sports session usually lasts 1-2 hours, equipping a lithium battery with a capacity of 5-10 kWh can ensure 1.5-2 hours of navigation under high-power output and high-speed operation. For instance, the eLite electric outboard motor from EPropulsion has a power of 500W, with a maximum input power of 750W in sports mode. Its maximum speed is close to 5 knots, with a range of 45 minutes in full-power mode and 1.5 hours in half-power mode. For short-duration, high-intensity water sports experiences, this not only meets the speed demand but also guarantees a certain range.
