Welcome to the board. That info is usually in your owners manual and the service manual. If you have a new motor I would get both manuals. Your dealer should be happy to tell your also.


I do not know but on 4 strokes I would expect to see engine oil changed with filter. The valves adjusted and the lower unit oil changed.


They may also check timing .


Anyway I would ask your dealer. Some dealers at this years boat show said they do 20 hr service for free. That was a Honda/Merc/Yamaha dealer.
