John, I asked the same question. The water piping continues inside the exhaust untill the downward part of the pipe aka the rubber hose.

Hope this helps.

These are injection elbows that we made up ourselves as, the originals were to low and water would have run back up the exhaust.

Where you see the water being injected into the exhaust, this is a double skin, exhaust gas runs up through the middle section, then around that is another stainless steel elbow of larger diameter which forms a water jacket within which the sea water runs to cool the exhaust.

Where you see the elbows terminate in the exhaust hose, this is where the water leaves the jacket and mixes with the outgoing exhaust gases.
Can send you a diagram should you want to make one for yourself.

This is a serious enquiry, I feel my turbo is a little vulnerable and an exhaust elbow similar to yours is being contemplated.

I like the gang photo.

Pressman, thanks for that. No need for a diagram, after seeing Hightower's picture I undestood how you'd done it. The lower section, from the turbo to the elbow, appears to have heat shielding around it. What sort of thickness have you used for the tubing of the elbow?
