are the tools needed for a rotax 503 metric or SAE
Rotax is from Europe, Austria to be exact. Metric is what most sites say. I have only tinkered on one, if I recall correctly all fasteners were metric apart from some of the SAE mounting hardware on the brackets, etc (but not on the engine). Don't remember pulling out the SAE tools until I got to the airframe.
Separate names with a comma.
