I want to pass this information on incase someone else has same experience. Since my boat was new I would occasionally get a low oil pressure alarm activation. I would immediately shut down the engine and then restart it. This would always fix this issue, temporary. I have a 2019 A22 with a PCM 409. I have about 105 hours and I have had the alarm activation at about the 10, 60 and 94 hour mark. I took my boat back to where I purchased it after the issue at the 10 hour mark, Tilly's Marine in Norco, Ca. They found nothing wrong. Following year I would once again have the same alarm activation and the temporary fix was the same sequence. So now that I'm a year away from my PCM warranty expiring I decided to contact PCM directly. After giving them my engine serial number they emailed me back and told me that my batch range of serial numbers indicated that I most likely have a bad or faulty oil pump. They told me to take my boat to a PCM approved dealership for an oil pump replacement. I find it interesting that my boat dealer did not know anything about this oil pump issue.
