Diverter valve

I am attempting to install a diverter valve in the raw water cooling system on my Yanmar 2GM20 to make it easier to fill the raw water side with antifreeze for the winter. The problem is that the hoses are 5/8", and I have not been able to find a diverter valve that size. What are my options?

Check out the Groco SSC series insert. You can put one in and make a safety seacock that allows for easy winterization and /or emegency bilge pump.

Use a 3/4" or 1" Valve with a 3/4" (or 1") to 5/8" Threaded Reducer?
I really like the Groco “SSC’ Flush Kit Diverter, that Jon D recommends.
