FLIPPING THE SWITCH

Much reporting focuses on reasons why one might choose electric marine power. The issues of range, speed, noise levels, winterizing and ethanol challenges, lake restrictions, environmental concerns and more all must be resolved on an individual basis. Little gets said about how a boater choosing to repower with electric actually gets that accomplished. Is it DIY? And if not, how does it get done?

Are you considering re-powering with electric? Here's a look at what it takes to cut the fuel line and plug in.

HOW FAST, HOW FAR AND HOW LONG?

Electric propulsion can provide speed, range and runtime, but not all at once. An electric boat, motor and battery combination might top 25 mph for an hour. The same boat can also travel more than 50 miles at 6 mph, or longer still at slower speed. That makes the first step in going electric determining how far, in miles, you want to go fast, and how long, in hours, you need to go slow. Then match a motor and batteries to suit.

PORTABLE PROPULSION (DIY) For small boats pushed to modest speeds, small, light options from ePropulsion, Torqeedo and Elco-equivalent to 3 hp gas outboards-easily clamp onto a transom yet store within a lazarette without worry of spilled gas. Most go for about an hour at full throttle, or 90 minutes at cruising speed, from one integrated or small external battery. These range from $2,500 to $3,500 for the motor, battery and charger.
