Hi there, is there a way to find out the cause of an alarm on the R29, both at the time of the alarm, and later, after the fact? I was on a sea trial of an R29 last week and we got an alarm - there was an audible alarm and a check engine notice on the Yanmar monitor screen.
The helmsman could not see what was causing it right off, and we were pulling up to the dock anyway so he figured we'd address it there, but a minute or two later, before we'd managed to tie up, the engine simply shut off. (Fortunately we were almost at the dock at the time and the captain jumped off the boat and just made it onto the dock, where I threw him a line and he was able to stop us using a cleat and pull us in.) We'd been running 18-19 knots or so for maybe 15 or 20 minutes to get there (not quite full throttle), so we suspected it might have overheated, but there were no funny smells or sounds (other than the alarm, which didn't go off until after we'd slowed down in the marina), and I think it's rated to do this, so it's certainly not clear. We also checked the strainer after we were tied up and there was nothing in there.
Is there a way to confirm what caused (a) the alarm, and (b) the shutdown, without hooking up a diagnostic computer to the engine? Also, is there a system that would detect that you were running out of fuel and alarm in this way? (Would a fuel shortage ever cause a check engine warning?) Any ideas much appreciated.
