The final piece, an anti-siphoning vent valve fitted and connected. As the raw water cooling water is ejected out of the exhaust, this valve is required, as the generator is mounted below water level, to stop the raw water siphoning back into the engine.
With the shelf fitted back in place.
It is now up and running, and so much quieter than the old one, both inside the engine room and outside from the exhaust.
