Does anyone have any recommendations on replacement manifolds for a 496? I'm planning to replace them as a preventative measure but don't love the $1500 price tag for OEM Merc ones.
I see Barr makes them which saves a couple hundred... Wondering if there are any other options out there that I'm not finding?

You will get all sorts of opions on aftermarket, I stick with orgianls and replace every 5-6 years since I run in salt water. Remember Gas is the cheap part of ownen a boat
