Riser Trouble

[DemersChrisG]

I took off one of the exaust manifolds and out shot a ton of water from the exaust ports. The manifold/riser gasket was almost gone so I wasn't suprised. I will replace that, but I was wondering about the risers themself. They are rusty on the inside, but theres no damage to the mating surface, or signs of holes from corrosion. What should I look for in riser/manifolds as signs of trouble?

Re: Riser Trouble

Its a saltwater engine. To clarify; I know that the gasket was worn, and this was a water entry point. The actual manifold/riser though, what are qualities that one lloks for the determine if replacement is required. Obviously there is corrosion because of saltwater, but to what extent?

If salt water is in the cylinders for 24 hours, we call them junk.
