I'm still not totally clear, but I think you are talking about flushing the raw water out of your engine. If so, you certainly don't need to spend $100-$300. I use a T that comes with a radiator flush system. I've installed the T in the raw water line, prior to the raw water strainer, with a simple hose valve which attachés to a short (8') garden hose. I put a 5 gallon bucket in the cockpit, run my dock water hose to it. I start a siphon in the short hose, hook it to the T, turn off the raw water intake, and open the little valve at the T. Presto, a fresh water cooled motor! Now...I've actually taken it to the extreme, by stopping at the guest dock as I enter the marina. I fill three 5 gallon buckets (instead of one with a dock hose supplying it). I have another little hose valve on the intake side of the short garden hose. I start the siphon and get back underway, using the buckets to supply the water (shutting the valve briefly when I transfer the hose to a new bucket). By the time I get to my slip, the motors douched and ready to shut down . The three buckets fit into each other and sit in my locker. You could use your galley sink instead of the buckets if it supplies enough water (mine doesn't). A little fanatical maybe, but raw water (and idling at the dock) is a terrible thing to do to a nice diesel! Anyway, the whole set up is probably $20. Originally I was hooking the dock hose directly to the T, but was advised against it (in this forum), as controlling the proper flow for the pump is impossible. The siphon allows the pump to control the water volume.
