Re: merc 25 rattle,

I had a loose rod cap make those noises. It was a new motor and started making the noise after a few hours of running. The dealer took it apart and found one rod cap bolt gone. They told me it was probably made during a strike the factory had. They replaced the powerhead...1980 OMC 140.
