I have a 2005 420 Sundancer with deiseal engines. Recently, on 3 separate occasions, I have had one of the engines just cut off when I was docking at low RPMs. I have had both alternators and all batteries replaced in the last 2 years. Has anyone else experienced this problem?

This is an elemental first thing to check. From here the problem could be electrical or fuel delivery related, but if you have just run the boat and it dies when you get back to the dock pretty much rules out clogged fuel filters, etc.

1. lo idle works, but as it is 100 RPM below the normal, make sure the engine has been allowed to warm up or stablized after running. In my case the engine had been shut down for an hour and while not a cold start, I rushed it. Now after start, I run the engines up for a couple of minutes at 800 RPM before selecting low idle and if approaching a dock I now have an awareness of the potential issue. Lo idle is supposed to be only 100 RPM under the regular idle. You might check what your regular idle really is.
2. What surprised me was the lack of a low oil pressure alarm. Searay told me that in 2004 ish the low oil pressure warning was moved out of the system monitor into the smart craft. additionally, around '04/'05 the warning was left out of smart craft. The wiring is there, but the smart craft isn't programmed. Just wondering if you got the low oil pressure warning when youe engine shut down?
