Boats!!! It's always something!!! :dead1:

I bought brand new complete CMI E-Top cool collar headers/tail pipes in March 2005.
They have 100 hours on them. Yesterday I find that my motor is hydro locked when I tried to start it. The #6 cyl is filling up with water immediately after cranking motor w/ no plugs to blow out water. I "assume" it is a crack in the header pipe. No water in oil. - sounds like header leak. . . .yes?
Anyhow, "if" it is a header issue, my headers are 4 months out of warranty. How lenient is CMI on this type of issue?


BTW: Almost had a wonderful 45 mile trip home on one motor @7.5 mph!!! But thanks to some friends who went 200% the extra mile, I only had to go about 19 miles. It is now on the trailer, and I am about to remove the suspect header and pressure test it. Many thanks to OSO/Speedwake members: PatricklHill & Rogman as well as some other friends!!!!!!!!!!

my experiences is that they're extremely lenient. I have had issues twice and both times CMI came through for me.

Headers are fine! Unfortunately!
That means blown head gasket, or cracked head or cracked block!
Any guesses?

Boat is now in NC and in the hands of Joey Griffin.
Gue$$ I'll find out $oon. :( :dead1: :(

head gasket - that's all

the chances of a cracked block or a cracked head on an engine recently rebuilt and maintained as well as yours are very slim.

Joey uses Felpro Blues - if you have blown a head gasket ask him specifically to use Cometics instead this time.
