Please see pics. 76 hours on 4.3MPI 250hp Mercruiser. A lot of rust but I don’t know if it is serious. Manifold/riser never replaced. Mounts and bolts look overly rusty. Thoughts and advice appreciated.
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.
