Over the few years we have owned Garulfo, we came to notice that the anti siphon vent for the engine that exits in the starboard cockpit drain hole was a good tell tale of a restriction in the raw water line:
when everything is clear (intake thru hull, vetus strainer, transmission heat exchanger, impeller, etc), the stream of water out of the vent line into the drain is continuous and silent,
when the flow is restricted, the initial spurting of water and exhaust gaz continues to the point of becoming annoying and I know i need to go and clean something. After clearing the line, the flow is back to normal.
Do other A54 owners share the same experience? Do my conclusions make sense, or is it some kind of coincidence?
Any feedback welcome!
