I now see that there are many happy users, and it appears that this could be a handy device for those who use it frequently. In my case, however, I only have one engine, and lay-up once a year, so the method I described is easy to employ. And, the rig I use is used at lay-up anyway to clean and flush the engine room bilge. Having been indoctrinated, in the 60s, into the marine engineering world by a fellow who grew up during the Depression and W.W.II, I chose made his mantra mine: Use it up, wear it out, make it do. The "make it do" part induces me to think twice before buying another piece of gear to ease a task which could be performed with something already at hand. So, I seldom do so, unless there are compelling reasons. Insofar as the antifreeze, one person questioned my "polluting" and so I feel compelled to say that I only lay-up while on the hard, so no AF gets into the water. Further, and I do use the "benign" antifreeze. John "Seahorse" Ron Barr writes: Truelove wrote: Adapt a 1/2" or 3/4" plastic 1/4-turn valve on your garden hose. On the other end, install a long brass nipple. Close the seacock, remove the top from the strainer" Which is true you could, but having a handy length of hose and garden type push snap fittings on the Thoroflush units - then all it takes is a turn of the levers and you're off an running. Taking the tops of the strainers is something I only do for cleaning - always the possibility of being careless and damaging the gaskets etc. KISS. Incidentally as I posted elsewhere use non-toxic anti-freeze.
