[C320-list] Yanmar exhaust architecture

[Graeme Clark]

I have just transitioned from one/third shared ownership of hull #303 with a Westerbeke to sole ownership of hull # 366 which (I have been told) is one of the very first to be fitted with a Yanmar 3GM30F engine.

The exhaust arrangement/architecture is very different from the Westerbeke and I wondered if this was now “standard” in all Yanmar engined 320s or has it been superseded with something else?

The exhaust is on the starboard side of the engine, so there is a length of lagged exhaust pipe as per this photo

which then connects  to a section on the port side where the water is injected. The entire assembly looks a bit ‘home made’!

If I have to replace the exhaust “elbow” (in reality not an elbow at all) where do I get this piece or is it custom made by a fabricator.

If anyone else with a 3GM30F has a photo or diagram of the exhaust arrangement I’d be most grateful

Many thanks
