Evoy Announces 300-hp Electric Outboard Engine

Electric propulsion continues to dominate R&D for countless marine companies, all hoping to bump up the power and range of these engines while decreasing the price to satisfy a greater universe of boaters. Thus the early September announcement of the 300-hp electric Evoy outboard comes as no surprise.

Delivering 225 kW of continuous power — the equivalent of 300 hp — the new Storm engine is the most powerful electric outboard ever put on the water, according to Evoy. The company also announced partnerships with three boat builders: Finnish Axopar, French Iguana Yachts, and Goldfish.

The engine weighs approximately 595 pounds and is powered by two to three batteries (depending upon range) that weigh about 840 pounds each. Evoy says the battery modules are designed for 3,000 charging cycles with 70 percent depth of discharge.

Evoy owners can monitor their outboard using an app that delivers near real-time information about charging and sensor readings among other features.

Electric outboards like electric cars make no sound and emit no fumes. But their range is often limited: Evoy states that its electric engines can travel about 30 nm at planing speed or cruise at 5 knots for up to 12 hours — depending upon the boat size, weight and design as well as sea conditions.

A Norwegian company, Evoy mainly sells throughout the Nordic countries and Europe. It sells to the United States and Japan on a case-by-case basis. Storm is available for preorder and is priced at 74,900 euros ($75,800). Battery systems are available for normal, long and extra-long range and cost 69,800 to 209,400 euros ($70,639 to $211,914).
