Electric Outboard Motor Range

Date:18/02/2016   View: 1096   Tags: Outboard Motor Range

When to buy an electric outboard motor, the first thing you should consider is the range. The battery is the fuel tank of your electric outboard motor of your boat, thus, the more battery power available the more “fuel” available. Range will ultimately depend heavily on the type of cruising you plan on doing and how many ‘battery banks’ you have available. Wind, water current and water conditions also affect your time on the water. A general range optimization strategy is to find the “sweet spot” where your speed and amp draw will get you the most range. Generally this means drawing back on your knot speed to approximately 50-60% of your hull speed and using around 20-30% of your available amp draw.The amp draw to speed is not linear, however, there is a “sweet spot” in which the range is optimized for approximately 22 nautical miles while maintaining an approximate speed of 4.2 knots and at the same time only drawing 23% of the available amp hours. (based on a 200Ah system).So we get the conclusion:by sacrificing a few knots, there is a 145% increase in range!
