Keeps your battery charged.

Keeps your battery charged.

The Idle Charge feature monitors your battery’s voltage state, and will increase the engine rpm in order to provide up to 48% more battery charging at idle. This supports the greater power demands of today’s sophisticated marine electronics and accessories, letting boaters and anglers safely stay out on the water longer.
