I was invited back channel to elaborate on the known problems with the on-engine filter for the benefit of our Yanmar friends who may come across this thread either now or in the future.
There are two issues the boat owner's research uncovered: - Bleed screw on the filter housing - over-tightening the bleed screw tends to crack the housing. How much is too much? When you figure it out it's too late.
- Vibration failure - the ring that holds the filter bowl is known to rattle loose from engine vibration.
