rust and corrision

I have rust at the manifold gasket, motors mounts and other part on and in the engine cabin. Any thoughts on the pics? 79 hours on the engine. Mercruiser 4.3MPI 250hp.

Hi, new member here. I currently have a 2006 Rinker 250 but I’m looking to purchase a Sea Ray for this season and I found a 2008 Sundancer 310 for a good price which is a bit of a red flag. It’s a former saltwater boat and I know the issues that come there. Before I negotiate think about...

Anyone put damp rid or anything else in the engine compartment to remove moisture/ dampness? Other suggestions? I want to get it dry while it's stored for the winter. Thanks..
