I have a Vetus loop in my exhaust line. Mine shoots out. Are we talking about the same thing?

How much water comes out is only an indication of the back pressure in the mixing elbow and exhaust system.

It has nothing to do with the effectivness of the device. What's important is that AIR has to get IN when the engine shuts down.

As an altervative, I installed a simple tee at the high point of my loop, and lead the air bleed to a fitting in the cockpit right above a drain. A steady dribble of water tells me right away that the water pump is working. Any interuption in water flow is immedietly obvious by sight and sound to the helmsman

We have that sort of setup on both our main propulsion engine and genset.

Ours are setup between the heat exchanger and the exhaust manifold. In this area, the water is under full pressure from the waterpump.

We limited the amount of water that can go through the fitting on the top of the loop by using 1/4 inch diameter barbs. Quite a bit of water still comes out. It shoots out downwards because we have 90 degree fitting at the hull.

A lot of people have commented on the water coming out.

The water that comes out shoots out the side of the boat about 3feet at first i thought that my exhuast exit run was looped to high [6ft above water lift muffler] so I cut it down to a straight shot with no loop in the exhuast hose and I still have the water shooting.
