I never really saw a good reason to drain headers…are you really going to go into your bilge everytime you shutdown the engine and drain the headers? If the answer is no, then you are wasting your time. In the event of a leak; even if you prevent a hydro lock situation; small amounts of water will be making its way into the engine every time you shut down.
salt water will make quick work of your valves, pistons, and cylinder walls. What’s the point?
anyways I know I didn’t help…but you may be wasting your time.
good luck.

my plan is to have the headers drain after every use either from me doing it manually or preferably have it done automatic every time i shut down. That is what the line does if it is going out the transom as is being done by some on this thread.

Drain
I know its an old thread but I am in process of figuring out how I want to set up a drain system for my cmi headers. I have made some fittings with a 3/16" hole to fit where the blue drain plugs are, rather than putting a fitting through the transom, how about draining into one of the unused the sea strainer ports? When boat is under way additional water could go up through the fitting rather than loose water through the open line at transom? When the motors are off and no pressure in the strainer the headers would drain into the strainer? Thoughts????
