The engine is coupled up to the prop shaft via the gear box, the black pipe is for the hot air extraction from the engine to the outside and the silver one is the exhaust pipe. An MLS FP100 fuel filter has also been fitted and can be seen just to the right of the black piping.
That’s a beast of a silencer!
Exhaust pipe is coupled to the hospital silencer and the stern greaser tube and tap is connected (just for the non-boaters - this goes to the stern gland and prevents ingress of water - the grease is forced into the tube via the tap after every cruise)
Centre above the weed-hatch access is the hydraulic ram for the steering and the two pipes on the left are fuel stop-cocks.
The heart of Still Rockin is almost there!
