Centek 1200328 Inline Check Valve (51mm Hose) (from ASAP Supplies)
I am thinking of installing one of the above check valves between water lock and exhaust manifold. (The waterlock is a Veus LP50)
My concern is that the water lock is only about 40cms below the manifold and retains about a gallon of water which I suspect could find its way back up into the exhaust manifold and through an open exhaust valve into a cylinder in choppy conditions.
Saling heeled to port would also mean the effective vertical distance would be reduced further increasing the possibility of water getting into the manifold.
There is a goose neck at the transom but the 50mm exhaust is 3m long so any water in it drains back into the waterlock when the engine is stopped.
My other plan was to install a solenoid valve on the waterlock drain which opens when the oil pressure switch closes (ie engine is stopped) and drains the WL into the bilges.
Am I being over cautious?
