List
Looking for replacement belts for the cooling fan on a 503 and a
447... I recall that one engine had a belt made by Mitsubishi... the 447
..size 10x590 . also had Rotax 94_4 B stamped on it.. I also have a
,made in Taiwan, 9.5x650 that may have come off of a 447. Just looking
for a local purchase...and would trust anything made by Gates...Herb

I think that if you first match the width, so it fits into the pulley correctly. second match the length so that the belt tightening adjustment is around 1/3 to 1/2 of its travel when taunt. Any automobile belt should provide good service.
Maybe someone smarter than I can shed more light on the subject.
If because of differences between metric and our standard,. If you can't match the width I would go with the next narrower belt. provided it rides in the pulley on the tapered sides, not the bottom of the groove. A wider belt will ride high in the pulley and have more of a chance to pop out.

Take the old one to any auto parts store and start comparing. Nothing magic about a belt that drives a tiny fan.
