Dear Sirs,

my Yanmar until now as loud and as reliable has a cooling water problem. The lid of the water pump has been replaced, all water leading pipes a new, we have lowered the sea water filter as low as possible. It seem to work, but I do not think that this is the only reason. Is a new pump the solution? Could it have another cause? Thanks in advance for your kind support. Elimar
