Stainless Marine Manifolds

I run in salt water about a 100 hours a year and flush with salt away after every use. My PCM manifolds lasted about 2 1/2 years. The corrosion of manifolds and risers wasn't too bad, but was severe enough right at the edges of the water passages that they definitely needed to be replaced. The economics of just replacing my PCM manifolds is still probably the best deal, but I would really be unhappy to have salt water leak into my 351. Stainless Marine claims their manifolds will leak externally eventually, but they have had only one set in all of the years of business leak internally. I like that failure mode. Does anyone have experience with these pricey manifolds? Worth it or should I just keep pulling my stock manifolds and risers every 100 hours to check them.

All I see on the Stainless Marine website for stainless manifolds fit engines that start with a C and end with a Y or maybe a T if you use the full name.

Maybe I'm looking in all the wrong places.

Gary has you linked to Ford stuff though

Yeah, I looked at the website again. There isn't a lot of information other than calling it a SB manifold, but the photo of the gasket sure doesn't look right! Barr has an aluminum manifold for SB Ford motors, but it only has one hole for a bolt on each port. Dang. I don't care what it would look like under my doghouse if a manifold lasted longer. I see quite a few Nautiques go up for sale with no motor or a fresh motor out here in salt water land. So I will stay on it. Maybe consider a HiTek.

Thanks to CCF. Without my half closed cooling system and Pro Tec conversion I wouldn't be riding twice a week all year.
