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.”
