Not sure if this answers your question but my boat is naturally aspirated which means it does not have a added device such as a super charger or turbocharger to push more air into the engine. The naturally aspirated are more reliable normally but from what I've heard about the new ACE 300 rotax is a maintenance free supercharger. I have a 2019 223VRX that I took it out and ran it hard Friday thru sunday this weekend with 10 on board Saturday.. a month ago and already put ave 26hrs on it. Absolutely no issues. The only blip was when i dropped in a river on a dirty boat ramp. I sucked up a lil stick that ended up clearing on it's own after a lil vibration whole turning up the throttle. My engines also do not have catalyst. I heard people were having issues with the O2 sensors.

I am one of those people. My O2s are always going bad. Maybe my engines just run too rich/lean. IDK, but doesn't seem to hurt anything.

The O2 sensors are not very appreciative of salt water exhaust system cooling. Exhaust system needs to be flushed regularly with fresh water. I was glad to hear that Rotax are coming out with more non catalyst engine.

FYI, I have had the same issue with my 2017 2430 both engines went through the trailing O2 sensors in first year, you can replace them with the Bosch Sensor located at your local Advance Auto Parts, part number 15122. $34.99ea. You will have to swap out the connector, but they work like a champ. Haven't had an O2 error ever since.
