20 hp

  • Overhead cam provides smooth, quiet and efficient operation

15 hp

  • The 15 hp FourStroke powers accessories with its reliable alternator (6-amp, 76-watt for manual-start models or 10-amp, 126-watt for electric-start models).
  • The through-prop exhaust submerges and minimizes exhaust noise.
  • Our overrev protection feature limits engine rpm if maximum engine speed is exceeded.

9.9 hp BigFoot and ProKicker

  • Our 2.42:1 gear ratio and four-blade propeller deliver maximum thrust and slow trolling speeds.
  • Peace of mind is provided by durable gearcase design and dual water inlets.
  • Available in two shaft lengths, 20 and 25 inches, for multiple applications.
  • The standard water-cooled fuel pump provides consistent fuel delivery - even under hot ambient conditions, regardless if the engine is pushing heavy loads at peak power or trolling at idle speeds for long periods.
  • The 9.9 ProKicker features a compact, integrated power tilt and a heavy-duty transom bracket for maximum strength, speed and durability.
  • 9.9 ProKicker graphics compliment the OptiMax ProXS and Verado main outboards. Installed next to a ProXS or Verado outboard, the improved ProKicker graphics will make your rig stand out from the rest of the pack.

8 and 9.9 hp

  • A standard manual recoil, even on electricstart models, provides added safety in the event of a drained battery.
  • Easy starting and fast idle warm-up are provided by manual choke and primer.
  • Only 7 pounds heavier than a comparable two-stroke, it's one of the lightest fourstrokes in its class.

4, 5, and 6 hp

  • A standard automatic cylinder decompression system greatly reduces starting pull force for effortless starting.
  • The 4 hp model delivers ultimate portability with its integrated fuel tank and shut-off valve to prevent fuel spillage.
  • A full forward-neutral-reverse side shift is standard.

2.5 and 3.5 hp

  • Patented one-piece integrated cylinderblock design provides added reliability by eliminating gaskets and fasteners and makes the powerhead much more compact and lightweight.
  • Check oil level without removing the cowling with convenient, easy-to-view sight gauge.
  • This engine delivers maximum performance with the largest displacement in the 2.5 hp category.
  • A twist-grip throttle and 360-degree steering make it easy to use.
