Mainly brass 'freeze out' plugs.

"That is it on the block, but if you're using anything else on the longblock, don't forget the camshaft, the circulating pump and the stainless head gaskets. And that's if you are only using the longblock. We won't even get into the bolt-ons."

The cam is a low rpm design with reduced valve overlap (to prevent water ingestion).

Be sure to change the engine circulating pump as well. The marine pump has a stainless steel back plate and a bronze impeller. The automtive pump will not hold up in salt water.
