Annual service: what to do and what you need
Every 100 engine hours or once a year, whichever comes first. The boat owner can do 11 of the 15 steps; 4 are dealer work. The owner-facing narrative for the steps is being prepared by the Merkür Deniz service team.
Step narratives, plan names and glossary definitions come from the Merkür Deniz workshop records and are in Turkish for now; intervals, step counts, parts lists, prices and capacities read the same in any language.
