Re: [Amel Yacht Owners] Onan genset trouble code "seven blinks"
We have had similar, recurrent problems on our SM #240. For some reason, the impellers we buy for the Onan have a tendency to lose blades, which then get trapped. By comparison, we have not noted that with the Volvo drive engine.toggle quoted messageShow quoted text
One thing I have noticed: even when the engines (either Onan or Volvo) are not putting out sufficient water, there is a “throaty” exhaust sound.
Even better, which I don’t think I can pass on, is what happened when I had an expert on board to look at a water flow issue. He put his hand on the side of the Onan, just downstream of the impeller, felt the surface for a couple of seconds, and diagnosed the problem immediately.
But you’re right, the fix is well within anyone’s skills who follows this Amel site.
