[C320-list] Drain aqua lift muffler? Engine won't start after charging batteries overnight

[Jeff Smith]

Dave,

This does not answer your question, but I simply close the thru-hull for the raw water pump if I spend more than 10 or 15 seconds turning the engine over. For me, the 15 - 20 seconds it runs without raw water is less of a worry than if I accidentally flood the engine. My reasoning is it will take at least a few minutes to come up to temp, and I already have some water in the circuit.

I used to be deathly afraid to start it without the thru-Hull open; now, I am not nearly as fearful (as maybe I should be).

So, I am wondering if it is plugged up.  Not having the ability to drain it could ultimately lead to a big problem  (flooding the engine by a backup into the exhaust elbow??).

Either situation should be fairly easy to remedy (assuming I don't crack the muffler unthreading the assembly.  Installing a new drain petcock probably would be a good idea too if I go to that level of effort.  Anyone have experience with this?
