Flush Plumbing Retro

[Hook'd]

Hi folks, I'm gonna plumb in an engine flush line, and need some advice. What is the ID of the raw water pipe feed (DPA)? Any advice on where to get a tee fitting for this (fresh water from transom fitting to raw water line)? Type and material? Other advice?

Thanks,

Well a good start would be, just what is the engine and year?

1-1/4"

however why not simply use the muffs?

Thanks Scott. Muffs just seem like a hassle when I'm using the boat a couple times a week. And each time I worry I'm getting enough recirc. Maybe overthinking?

Do you use muffs on yours?
