Merc/CMI service bulletin
I ordered the parts to eliminate the bypass hoses on my 525 headers.
Should I use some type of sealant or teflon tape on the fittings?
Some of the connections are metal to metal and some are plastic to metal.
Please keep this on strictly TECHNICAL level. The other issue has been beat to death.

Where can we get the parts?
Is this mod needed or is it just for installation of the new headers and tailpipes? The service bulletin does not say that all older set-ups should have this mod done. My headers have always stayed cool. When I stop the boat and check the engine room one thing I do is see if I can hold my hand on each header tube.
And here is a link to where that bulletin was posted since I'm sure not everyone saw it.

I don't know if it's a must have. I'm just trying (hoping) to lessen the possibility of having issues.
