Exhaust manifolds

[Campione204]

What are best kits for replacing exhaust manifolds? Currently have Yamaha manifolds on a 1992 small black Chevy 350 in a Ebbtide 204 Campione that are rusted and cracked that need replacing. Looking for good replacements. Tia

I installed Barr Marine (made in USA) on my 4.3 five years ago and so far so good. Just give ‘em atop coat of Rustolium becaus if you’re in a damp climate they will get surface rust a a season or 2. Remove any paint from the sealing surfaces for the manifolds & elbows and check flatness with a straight edge & feeler gauges (flat to less than .002”).

do you have a yamaha drive or an OMC drive?

the Yamaha drive is closer to a mercruiser, however you have to verify fitment
