Re: Steam? Exhaust? Normal?

I am having this exact problem on a 1982 Mercury 70. I did not find any cracks in the baffle plate. But i will order one in case I am missing something. Where did you order it from?

You can probably find the gaskets here on iboats. But for the actual baffle, I went to www.crowleymarine.com. They have a pretty good website with clear diagrams.

Thanks to Wilde1 and Don there is hope for used parts as salavge yards can be a great place to find older NLA parts.

Ripped down the power head and found a broken upper water tube grommet (hard plastic not rubber). Could this cause my steam issue?

It would significantly reduce the water pressure through the engine allowing less water flow which would heat up faster and remain in the block longer than it otherwise would
