Suzuki 300 250 o2 sensor issues

[Unreel]

Wondering if anyone that has a 250 or 300 has had continual o2 sensor problems? I’ve got a 2015 with 315 hours and I’m on my 3rd o2 sensor. The original sensors were a problem and Suzuki put out updated ones that were supposed to fix the issue and 3-6 code. My last sensor I’ve got only 15 hours on and now getting the same stupid 3-6 code again which is the o2 sensor. Dealer has been good and paid for the parts under warranty and I’ve just replaced them myself so I don’t have to haul the boat out and to the dealer. They also claimed that they hadn’t had any of the new sensors go bad, only mine. Google search suggests this is a wide spread problem with these motors.
Now that my 3rd “fixed” sensor is throwing the same code I’m starting to get frustrated, only have another year of warranty and these are $400 a pop. Anyone having similar issues?
