Core Portability & Starting Features
  • Lightweight Twin-Cylinder Design: Weighing approximately 87 lbs (39.5 kg), it is exceptionally easy to transport and install on small boats, inflatables, or tenders.
  • Manual Rope Start with Auto-Decompression: Includes an automatic mechanical device that reduces cylinder pressure during the pull-start, allowing for effortless, reliable ignition even on cold starts.
  • Battery-Free Operation: Since it relies on a manual pull-start and a CDI microcomputer ignition, no heavy external marine battery is required, saving critical space and weight on small vessels.
  • Integrated Carry Handles & Resting Pads: Features built-in front and rear handles for a balanced carry, along with resting pads that allow for on-side storage without oil leakage or cowling scuffs.
