All to deliver an engine that works as hard as you do.
Maintains a desired rpm regardless of changes in load or conditions without adjustments to the throttle level position - a first for the outboard industry.
Exceptionally Smooth and Quiet
Tuned multi-chamber air intake minimizes airborne noise; fuel injector covers reduce high - frequency noise.
Industry-Exclusive Battery Management Technology
When battery voltage decreases, the engine will automatically increase idle rpm to boost alternator output and recharge low batteries to the proper level, protecting operators from draining their battery while trolling.
Easy to Maintain
The exclusive Top Cowl Service Door simplifies routine maintenance, letting you check or add engine oil without removing the top cowl. Hour-based maintenance schedule decal is located under the cowl, providing a quick overview of routine maintenance.
