Electric marine inboard motors

Elco Motor Yachts, Lake George, N.Y., has introduced new updated versions of its EP-6, EP-12 and EP-20 inboard electric motors for marine propulsion applications. The company said the new motors are half the weight and one-third smaller in length and height than previous models. This is accomplished by utilizing a patented airflow designed to enable the motors run cooler, which reduces the copper windings required and allows for significantly smaller and lighter castings, the company said.

Elco EP-Series motors don’t require a marine transmission, making throttle response and gear selection sure and immediate during close-quarters maneuvering. The motors are also silent in neutral and nearly so in gear, which the company said enhances onboard communication and make docking safer.

The motors are typically powered by lead acid or lithium batteries, with the number depending on the motor. Installation wiring is plug-and-play and the motor’s control box can be installed remotely to free up engine compartment space.

Elco’s EP-6, EP-12 and EP-20 are designed for boats up to 34 ft. in length and 13,000 lb. and can be used to replace combustion engines in the 6- to 20-hp range. For larger vessels, the company offers electric and hybrid propulsion systems ranging up to 200 hp equivalents.
