Hi All

,I am doing a condition inspection on a RANS S-9 with a Rotax 503, Single Carb, Dual Ignition. I tried using the Rotax  date of manufacture inquiry and it said "Number Not Found". I have noted some one else had a similar issue and one of the Rotax Site Moderators was able to find some info regarding that engine.

So here is the Serial Number. M 5171681.  I am trying to nail down the relevant Service Bulletins, Service Letters, and any other applicable information regarding this engine.

Please help me MR./MS. Rotax Moderator?

Thank you for your time

Carlos G.
