Completed winterization on the boat after my first season of ownership. Most everything was straightforward, but the raw water line for the generator was awful to remove from the strainer due to very limited space and a stiff, short length of hose. Heat and persistence was the only way to get it done and I'd prefer not to fight that battle again. As a result I've hacked a solution for next year to make it painless and quick to get antifreeze into the line. I purchased a second raw water strainer cup, drilled/dremeled a hole in the bottom until I could thread the 1" fitting, and then epoxied it in place. I looked everywhere on the internet and couldn't find something similar. For raw water strainers that open at the top there are commercially made substitute threaded caps with hose attachments for winterizing, but nothing similar for the Groco raw water strainers like this that are common on so many boats. Those commercial solutions have their threads facing outside of the cap; these Groco raw water strainers have their threads on the inside, so they're not compatible. Next winter I'll just swap in this winterization strainer cup, clamp on some clear hose, run it to the antifreeze in a bucket, and start the generator to pull it through the raw water system.
