    Install after the shutoff valve at the intake to the cooling system.

    This is my flush out system. Simple addition of a hose bib to the rw hose.

My thought was it also allowed the strainer to be flushed. As there were seasons where we were running after freezing temps arrived. When we got back to the dock after a fishing trip we put potable antifreeze in the bucket and ran the engine pulling the antifreeze mix from the bucket until we saw antifreeze coming out of the exhaust. All we were ever out was around 2 gallons of antifreeze on a trip but we fortunately never had a freeze up problem.
    Yup, thats how we winterize. Not that I have in years if the boat stays in the water.. Global warming ya kno. Just reminded me to send AlGore some money for more carbon credits. Y'all buy them doncha.

    So you could suck the bilge water through the heat exchanger and out the exhaust? Should a removable filter be an advantage, given what's in my bilge?

    I have used my Perko Flush system for 22 seasons with zero problems. Fact.

    I use the same set up as in Jerry’s illustration. Not only does it give the large advantage of an emergency pump it also has you exercising the valves to prevent them from seizing up ensuring they will work when needed.

    I have the new Perko design with a stainless v-band clamp, it replaced the older version without a clamp. I read about some of the failures and figured that the old design and, possibly, installation/operation issues contributed (heat, over pressure, freezing, etc). The new valve has been on for over a year and works perfectly. I only run the water when the engine is running because the valve can be damaged from high water pressure: a quick prime, start the engine then reopen the water supply, close water supply and shut down engine. That said, I would seriously consider Jerry's design due to the simplicity and how quickly it can be used as an emergency bilge pump.

    My 270 came with a flush system which does what the plastic Perko unit does, but with separate bronze swing check valve and hose connection fittings downsteam of the inlet strainer. This has worked well for me and I'm not worried about the swing check failing in the closed position since i have a cooling water flow sensor that screams at me every time I start up until it gets flow. I suppose if it failed in the open position, I'd be getting a mix of fresh and salt water since I do this in the slip, but I'd find out if that was the case when I pull it to put away for the season as I'd get water out the seawater inlet.. The only other thing I've come to worry about is shutting down while the hose is connected which makes the pump impeller take a set in the opposite direction. I now start the engine, open the hose connection to flush then shut off the hose and quickly shut down the engine. A hose ball valve near the deck connection helps do this easily.

    Wow, $150 for a chunk of plastic. You guys are right. Need to keep it simple. I need to find a place to put the valve that's not to hard to access. Hmmmmmm....
