Groco SSC Engine Flush Kit

Was going to make my own 1-1/4"" flush adapter and then discovered this, really works great. This is a ""new to me"", old diesel boat with heat exchanger and existing seacock having a 90º bend to hose adapter, so the only hitch for me was, adapting the existing 1-1/4"" thread on the flush unit, apparently there is no such thing as a 1-1/4"" female thread to hose adapter, so had to use a 1-1/4"" coupling then male thread hose adapter. But it all works perfectly and I flush after each voyage out.

So I was about to create my own flush system when a came across these. Simple fact is even a boat as well maintained as mine and used frequently will still get scaling, and it just builds up over time at the dock. Flushing it can greatly reduce the ""growth"" of the scaling. Sure a lot cheaper than pulling after coolers and heat exchangers!! If nothing else the time it takes to flush will prolong the need the for full de-scaling. We all know what a mechanic costs to start pulling stuff apart, so the cost is relatively insignificant. Not giving it a 5 and almost a 3 because there is no safety or lock on the cap. they do turn on, but there is no catch or seat to keep them from turning out. I didn't leave it to chance to find out this cap was going to loosen, come out and flood the boat in the middle of the ocean, so used a simple Velcro strap till I come up with a better solution, but think you need something to ensure it does not find its way lose.

I would recommend this for anyone who winterizes the boat themselves. This makes the job so much easier. Close the seacock, pull the plug, insert the adapter, turn on the hose and go. No more fighting to pull off hoses, disconnecting hose clamps etc. I also purchased the pipe thread to hose adapter and spliced it into the middle of my hose so it sits up high instead of down in the lower bilge ontop of the seacock. Makes it much more accessable. It will alsocome in handy when I have to run the engines to clean out my slip once a year.
