    As noted before, this is an incorrect line of thinking. I get it that YOUR drains are clear, but that, in no way, means other engines will be. One experience with one engine doesn't mean it's the same for the tens of thousands of others out there and promoting that can only lead to someone following misinformation and ending up with a huge repair bill.

    These lines can, and do, get clogged - I've seen it many, many times. I'm offering guidance based on many years of real life experience... and quite honestly, with a heck of a lot more boats than you are experienced with. I don't mean that in a negative way - just that facts are fact.

    I pray you will be lucky enough to not freeze a block using your methods. You have every day people here with decades of hands on experience that truly understand the inside of a combustion engine trying to explain and help you understand the cooling system and risks. You on the other hand are to hard headed to want to understand.

    I agree with Juliery-"you can't fix ...."

    Long as you drain it before refilling with eco-antifreeze in a dilution good to 15 below, you should be OK. If your summer use plugs up the Mercruiser engineered, installed and marketed One-point drain system, you could replace the large hose barbs on the bottoms of the exhaust manifolds with drain petcocks. Those that fail to drain could be routed out with wire just like old times. Time to turn the blue handle now though.
    The aftermarket valves advertised below are 3/4" NPT which ought to have an inner diameter of 5/8", as big as your finger might be. The design probably has routine flow through it. My hoses were clean but you'd have to write Mercruiser to find out if clogging is a recognized problem. Big hoses!

    Once again you’re missing the point!!
    THE DRAINS ON THE BLOCK ARE WHAT WE ARE TALKING ABOUT.

    How do I post the “Banging my head against the wall” emoji?

    Never mind, it’s easier to ignore him.
