In the early 70’s, Ericson’s with Atomic 4 engines had a vertical standpipe made of steel pipe/tubing that was wrapped (with of ALL THINGS) asbestos. In fact, there was an early on warranty issue on my 73 E-32 and EY had sent me a repair piece
AND included a long strip of asbestos to re-wrap the repair section. …How times have changed!
Problem with those vertical stand pipes is they burned or rusted out in a few years. The cabin would soon smell of exhaust every time the engine ran at any length. The asbestos wrapping made it impossible to see the deterioration of the metal until after the fact of a failure. Of course – today – even the simple thought of using a heat proof wrap of asbestos is an absolute taboo!
When we re-powered to a Westerbeke diesel in ’91, the switch was made to an Aqua-Lift muffler system. There is no metal involved in their design and still to date today – no exhaust leaks.
Not sure exactly when Ericson stopped using this old stand-pipe design. It’d be interesting to hear if/how many EY owners still have the system in place.
