I just hit 100 hours on my 250hpdi and I am taking advice from everywhere here and taking it in for service. I checked yamaha's website for repair dealers in my area. There are a couple within 30 mins of me but some of them dont show the "yamaha certifications" like the 5 star yamaha factory outboard certificate. Does this matter??

There is a dealer about 2 hours away that has shows "factory trained outboard" and "master technician outboard."

My question is since I am only going to the basics which were recommended to me (change spark plugs, filters, change lower unit oil, and a new impeller) should I worry about all of this or does it even matter?? Thanks!
