Paint a new Yanmar 3YM30?

[jaffadog]

I am repowering, and have taken delivery of the new engine, a Yanmar 3YM30. The engine has numerous steel parts and fasteners that are unpainted (e.g. water pump">raw water pump bracket; starter solenoid). I think it might be a good idea to prime/paint these items before I get the engine in the boat. Otherwise, I think rust will set in promptly. Seems nuts to be painting a new engine. Has anyone else taken this approach? Any recommended paint? spay can of "Yanmar Gray"? Or spray cold galvanizing? or zinc chromate?

I have painted many automotive engines and I think it is a great idea. I would put an epoxy primer on first. I like interlux 2000e. After that any enamel or urethane will make it easier to clean.
