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.

The attached drawing includes component info. Edit: the wire colors on the drawing correspond to the wire colors on the components.

Without prior experience, programming the delay timer will be a challenge. There are over 33 timing sequences to choose from and a seemingly infinite range of delays, all selected by shorting the programming leads in a sequence or pushing either or both buttons on a programming circuit board which is not included in the purchase. After the considerable learning curve it's not that big of a deal but it's a steep curve getting there.
This may be a choose your battles moment. I can help because I've been through it. An option is to send me your timer (fits in an envelope) and I'll program it. Takes me maybe 10 minutes. I'll confess the first time took over an hour.

Neil, if you had one of those crappy Vetus waterlifts like I do, the plastic drain cap in the bottom of the muffler leaks all by itself, right into the bilge.
