Hi all, I have a seawater cooled Yanmar 10GM and it has a habit of setting off the 'water' alarm. It seems to dislike turbulent water but it will also happily run for an 1 1/2 quite happily and then go off for no apparent reason. I have checked the impeller and the seacock filter and there is always water coming out the back when the alarm goes off. I put it into neutral and after 30 secs or so the alarm goes off and I carry on for maybe another half hour or so and the same thing happens again. Its about 50 hours 'old' and probably needs a service but can anyone help with this specific problem . . . . ?
Thanks in advance.
