Exclamation Water siphoning back into the engine if the boat heels

From a related post:

Is there a problem with a Catalina 30 having water siphon back into the engine if the boat heels?

Yes, Catalina 30's are very prone to getting water back into the engine from the exhaust system. The center cabin location of the engine allows practically no space to construct the hot section (or dry section) of the exhaust system so that it extends upward before it drops down and into the inlet of the fiber glass water lift muffler.

Water typically backs up during long periods of cranking a hard starting engine, while healing during sailing, and even while the boat sits idle for several days with the raw water through-hull open and the siphon valve being stuck closed.

The best protection against water backing up from the exhaust system of a Catalina 30 is to be religious in keeping the raw water through-hull valve closed anytime that the engine is not running and by keeping your anti-siphon valve clean and functional.

Best regards,

Don Moyer
