Agree!

You are correct, the Groco wouldn't work with an I/O, it would backflow through the outdrive.

They do work great for winterizing the raw water head intake and AC though

It’s an I/O so the strainer is built into the drive; hard to install before that.

Zinc is noble. If salt water is running through there it will corrode on the exposed surface (Interior), and you will only notice it when it fails. Consider replacing the brass hose adapters with bronze.

It has been replaced with the steel mercruiser Y.
