Tinkering with the exhaust system

Last year I installed an automatic waterlift drain. With the marginal hot section rise on a Catalina 30 it's one more level of protection against water incursion through the exhaust. Every time the engine is turned off the residual water in the waterlift drains into the bilge. After the drain period expires the drain valve closes.

The drain valve is closed when the ignition circuit is on, open for five minutes after the ignition is switched off, closed following that period and as a fail-safe, closed when power is removed.
