I’ve had 2 new boats in the last 3 years. A 2020 sl450 and now a 2022 sl550. Both of them got 1k in lead with less than an hour run time and we surfed loaded up from the get go. Traded the 450 with 200hrs and not a hiccup. At 30 hrs with the 550 and no issues at all. Both of them the dealer did the 20 hr service.
