Is this a simple bolt on swap? I have a Gen VI 502 mag MPI that is being replaced by a new long block. Currently it has stock dry Mercury manifolds, elbows and 4 inch risers. Can I replace them with stock mercury wet style manifolds/risers/elbows? Yes/no...pros/cons? Thanks.

Picture of current set up

Why go to wet style? If changing exhaust, you wouldnt want to do SM or Imco, or such?

Looks wet to me. But i’m looking at it on a small ohone.

I'm with SB on this one. Current picture shows a wet joint setup with a 4 inch spacer between manifold and riser/elbow. The brass plugs shown would have an interconnecting hose for coolant flow between the manifold/riser if this were a dry joint setup.

You have a wet joint between manifolds and risers. If you didn't, no water would be in the exhaust and your exhaust would be on fire.

Ok...now im confused. I thought a dry joint was a set up that uses square gaskets and a wet set up (2005 on-wards?) has square gaskets with round openings on the sides like this: https://www.perfprotech.com/kit-rise...product/188519

If the current set up isnt leaking, Ill just replace gaskets when the dead engine comes out. But if it leaking at the joints, I was exploring options to see if it was possible to go with a set up like in the above link (manifolds, risers, elbows etc).

Thanks for the insights.

That is the wet style joint, meaning the water flows through the outer flange with the exhaust in the center, only a gasket separates them, a dry joint will have a jumper hose from the manifold to the riser, eliminating any water intrusion at the actual manifold/riser joint

Compare your current setup to a 496, you will clearly see the difference

Thanks......make sense. Still need to tear this one down and find out if they are bueno or no bueno.
