Rotax Discontinues 503 and 447 2-Stroke Engines


Rotax Discontinues 503 and 447 2Stroke Engines

If you’re in the market for a 2-stroke Rotax engine, you may have only one choice: the 65-hp 582 model. Bombardier Rotax has sold out of the 50-hp 503 and 40-hp 447 2-stroke models, and has no plans to manufacture more.

      According to Jessie, one of California Power Systems parts managers, Rotax will continue to manufacture parts for the 503 and 447 engines. “They have to make parts for at least 10 years,” says Jessie.

      Why did Rotax discontinue the 503 and 447?

      “Rotax stopped producing the 447 and 503 because the molds for the engines needed to be redone,” explains Canadian Rotax distributor Dave Loveman. “Before spending the resources necessary to do that, they asked dealers/distributors to give a projection of sales they expected moving forward, so that [Rotax] could justify the cost.

      “The feedback was that sales for those engines did not justify the cost,” Loveman continues. “Rotax at the time had ample supply of engines in stock and on hand at the dealer level to last 2 or 3 years. In the past, the 447 and 503 were also being used in the snowmobile industry. They have been now replaced with newer models, leaving the aviation industry as the only industry still using the 447 and 503.”
