Groco SSC Engine Flush Kit

Add this Safety Seacock Conversion Adapter after any existing seacocks for the utility of instant emergency bilge pumping and simplified winterization. This Conversion allows the engine's raw water pump to be used as a secondary bilge pump.

To use the seacock conversion as a bilge pump simply close the seacock while the engine is running and remove the quick release plug. Any water above the release plug will be quickly drawn in and pumped overboard. Or add a Groco BSA bilge strainer adapter for bilge locations remote to seacock. The included service adapter makes winterization chore of running antifreeze to flush cooling system simple and easy.

Comments about Groco SSC Engine Flush Kit:

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.
