Our 72-cc 2.5-hp portable outboard is the smallest motor on our roster, yet, it has some of the biggest news. Completely redesigned, it’s even more portable, easier to store and cleaner burning. It recently achieved a Three-Star rating from the California Air Resources Board (C.A.R.B) for Ultra-Low Emissions and now meets emissions requirements in all 50 states.

  • Available for tiller-handle control with forward-neutral shifting, 360-degree steering and an ergonomic twist-grip throttle
  • Only 37 pounds (15” shaft model)
  • Available in 15” and 20” shaft lengths
