A friend of mine has a Sea-doo GTS 2001 800cc and has problems
with ignition.

He is a car mechanic as profession so he knows lots of stuff but it in need of a service manual for this ski.

He already has a part-out list but is searching for technical stuff so
that he can measure things out and can check if numbers and measurements are correct.

Can somebody help with this?

edditted later:

In his hullnumber there is '5552', does this mean it maybe is a GTI instead???
