G21 or G23 100 hour service

[abstron]

Is it worth taking my 2014 G21 to dealership for 100 hour service? I can do oil changes and stuff myself, what is additional they would do for a 100 hour service? My dealership is a 3 hour drive away so is a hassle and wonder if it is worth taking it to them or not?
Thanks

The items for the 100 hour change are listed in your manual. If you are familiar with boats, then doing the 100 hour service yourself is not difficult. Many are simply checking certain items. But changing the impeller, changing tranny oil, lubricating steering linkage, changing the fuel filter, etc are straight forward.
