503 Overhaul Time
in 2 Stroke Technical Questions
5 years ago
Thinking of buying 1997 Challenger II long wing. The 503 DCDI was built in 2000 and is the original engine with 367 hours. I know Rotax recommends doing the overhaul @ 300 hours, but it seem like people wait longer to overhaul ? is this true?. The owner says it was decarboned and new gaskets @ 361hours. Can I run this motor to 500 hours if the compression checks good ?
