Low Oil Pressure
I have an 2009 X-45ss with the Indmar LY6, about 350 hours. The engine runs and sounds perfect, but the last time I used it, the oil pressure set off the alarm when I started it. I turned the engine off, checked the oil level, and topped it off with less than a quart. Turned it back on, no alarm, but oil pressure was hovering between 15-20 psi, regardless of the RPMs (i.e. even cruising, it would be about 17 psi).
I took it to the dealer, who confirmed the low oil pressure with a manual gauge. Dealer does not know what is causing the problem, and is recommending a new long block rather than spending the money to diagnose and repair, which strikes me as a little drastic. Any advice?
