Description
If the point where the cooling water is injected into the exhaust is less than 15cm above the waterline, then when the engine is stopped, there is a risk that cooling water will siphon into the exhaust system, and subsequently into the engine itself. Such siphoning may be prevented by fitting the Vetus AIRVENTH at least 40cm above the waterline.
The AIRVENTH comes complete with a skin fitting, hose clamps, and 4m of hose. Features a hose connection to the outside of the hull. There is a constant bleed off of cooling water through this hose, whilst the engine is running.
For hose ID sizes: 1/2″ (13mm), 3/4″ (19mm), 1″ (25mm), 1-1/4″ (32mm).
