Aluminum engine block internal coating suggestion

I have an aluminum outboard engine block that has some minor corrosion in the internal water passageways. I'd like to treat/coat these areas as I believe they are leaking water while running. The block is fresh-water cooled. Any suggestions?

Thanks

Latest suggestion has been Glyptal. It's been used for years on lifter valleys inside race engines.
