Marine Engines

Rapid response and lasting dependability.

To win race after race, season after season, you need more than speed and power. You need the consistently superior performance built into every O.S. Marine engine. O.S. knows a thing or two about taking the lead over the water. An O.S. outboard racked up 11 championship wins over a four-year period...and O.S. engineers always keep pushing to make the next engine even faster!

Whatever your ambition – upgrading an RTR, outfitting a scale or sport ship, entering competition – O.S. has an engine made to last longer and provide higher performance than any other on the water. For the best engine in the long run, call in O.S. Marines.
