CMI Headers
Anyone had a set of CMI's with any age on them? I have a friend who was thinking of buying some, but we were told by a guy they have a bad habit of cracking...He said even the new ones with the cool callar crack? Thanks!

first i'm hearing of that I though it was really old stellings you stay away from?
I know the navy uses the CMI tube tops for the SEAL boats so i would think they are pretty tough.

Never heard a problem with CMI's. I had a set for 5yrs. Like Haveit said, the worst problem was that rope gasket.
When I sold the boat they still looked great.
I have heard of problems with Stellings and Bassett however.

I bought a set of older CMI's for installation over the offseason.
Who knows what the BEST material is for the rope seals?
I hear folks mention fiberglass rope. What about some of the new teflon impregnated shaft log packing material? I guess its gotta be pyrex or some other heat resistant stuff, eh?

I've already tried the graphite rope. The only thing it does is cause the engine compartment to turn black and put a "dust" all over everything when they start to leak.
Just my experiance.

baja bailey,
I aquired several sets of the Navy Seal Tube tops. Some had pin hole leaks and I had them welded up. I cut the uppper tubes to make them fit my 25' Convincer with narrow exhaust outlets.. Since then I have reused the bottoms and bought new uppers for my 28' Checkmate.
As for the rope seals, I have had very good luck with the furnace door type of packing. I use a smaller dia of rope.. about 3/8" and the trick is to wrap the rope about the pipe several times and pack it into the clamp.. I did this the last time and I have no leaks.. the ones they sell need to be sealed at the ends. If you wrap four or five times.. there are no ends to seal...
I would buy CMI's again in a heart beat. You are advised to psi check them for any type of leaks before paying for them..
good luck
