Fourstroke

Whether you have a 2.5hp for your tinnie, a BigFoot for your pontoon or houseboat, or a 150hp for your runabout, the key elements of quality are always there for you.

The instant starts and clean, quiet operation.

All together, these elements combine to provide the engine security you not only crave, but deserve. That's because every component on our FourStrokes are designed to deliver ultimate durability.

More stainless steel, hard anodizing and our exclusive multi-step paint process adds up to superior corrosion resistance.
