Hi all - i am replacing the manifold and riser on my 1974 mercruiser 3.0 as the old ones were cracked.

The new design of the quicksilver manifold has two water ports whereas the new (barr) riser only has one (Like the original).
The gasket that came with the new manifold also doesn't match it.

I contacted the marine supply store that i bought them from and they assured me this is fine to use.

I really don't want any water getting into my new block.. ever seen this before? I feel like the water ports only line up maybe halfway at best then the water will just come out the manifold and run straight into the gasket.. potentially wearing it out?

thanks!
