Yamaha manual says inspect and replace as required at 100 hours. My dealer basically said that as long as it was running fine then no need to replace. Since I was used to the Mercury Pro XS 2 stroke that requires replacement at 100 hours, I had my Yamaha 250 SHO spark plugs replaced at 100 hours. Probably an over kill. My top end was no different so my old plugs were still good. So I think your dealer was following Yamaha recommendations. So if you aren’t seeing performance issues, you are ok.

thank you for taking the time to respond
Follow manual and inspect. Look for anything unusual.
At a minimum it will breakup any corrosion making them easier to replace later.
