just bought an 09 with 600's whats the best way to test them and can it be done without removing them?

Lost two 525's to CMI headers on the last boat. Now my 2007 with 700's - I have replaced one header, repaired another and just pulled the last two due to leaking. What the ???? CMI needs to pick up my $21K in repairs etc.

With all the horror stories I've read about CMI failures, I'm absolutely amazed they are still in business!!! Who in their right mind would buy from this at this point? Even if they offered a decent/proven product, I still would not give them a dime of my money! :mad:

Guy's thanks for all the imput. Why would you go back to CMI, if your replacing why not go to another brand?
Just wondering

For those that had leaks, how did you know?

Was water leaking externally? Milky oil? Wet plugs?

What's the best way to monitor the situation?

EXACTLY, try SM or Stellings. Too bad KE's won't fit. Don't know if IMCO fit, if they do, that would be the route I would go!:drink:

My oil temp. went out of sight. Hot exhaust gas blowing in the water wouldn't let the oil cooler do its job. Same thing happened on a friend of mines 38TG who had to replace all 4 of his last year.
