Re: Water in Cylinders

That is a great outcome. Now take it out and run it hard for half an hour to get it really hot. Then bring it in, cooling down slowly. Immediately do another oil and filter change, run it for another hour and then check it shows no sign of milkiness.
Read elsewhere my technique for starting those old Yanmars WITHOUT touching the decompression levers. The only time you may need to resort to those is when your battery is weak. All learned the hard way.

Consider fitting a quick drain at the lowest point of your exhaust so that at the end of the day after you shut the raw water intake you can drain any excess sea water trapped in the system.

May your Yanmar have a long and happy life.
