I know the header issue has been beaten to death.But I had 260 hours on my CMI equipped 525"s. No problems ever. Salt water for 130 of those hours too. Proper water flow,as well as water pressure(not the same),and proper flushing will keep them alive a lot longer.I just replaced them with Gen X CMI's. I pressure tested and inspected the old one's,for the heck of it and they are perfect. Boat is a 2004. Who knows,maybe I'm just lucky.But I wouldn't hesitate to buy CMI's again. BTW if anyone needs a set of used headers, let me know. Jeff

If my next boat (when and if I ever decide what that will be) has 525s I will be doing this.
Rent the jig from stainless marine, I think its just a deposit drill and tap, problem solved. http://www.cpperformance.com/p-16690...dard-exit.aspx |
Thanks guys.Used a combination of the ideas and came up with one leaking so I will probably just replace them with the Gen X CMIs.This will cover me for the time I will own this boat and give a future buyer some relief knowing they were replaced.I would rather put that money into 625kits at 300hrs but that will do me no good if the headers take out the motors.

You might want to give Dana Marina a call, I'm pretty sure they make a bracket now that fits the 525 but you now use any headers for BBC.
|
Also, CMI will test, repair, and polish them for a very reasonable price. It might be worth it to send them out.
I had a couple leaks, sent mine out this winter, they charged me $350 including shipping to weld them up. Alot cheaper than $5k for a new set. |
