About 2 1/2yrs ago Dana Marine stated that they were coming out with a conversion bracket for the bolt pattern for $325 per engine. You bolt on the bracket to your 525, the bracket had a standard block bolt pattern that would allow you to mount any header to it. Not sure if it they ever came out with the product or not, but it would definitely be worth the call.

I sent my cmi headers, (single engine) back to them for
Pressure testing & polishing... What a F'in joke... All they did was piss me off, they passed the pressure test, like 80 bucks or so... Then the polishing? (So they say)
Nope
Came back looking worse then when I sent them with one of my water tubes bent
Long story short over 600 bucks (between shipping & there bill)...a wast of time & money!
On a side note the "main" reason I sent them was to be polished! & I told them that! But they wanted to test!
I pressure test them myself every year B4 the season starts...
Air them up, drop Them in a cut-in "1/2" 55 gallon drum, look for bubbles!
I wanted them to look new again
Or at least better then when I sent them away
I will never deal with them again
They have lost a customer (ME)!!!

I am in the process of gathering parts to put together a 540 and exhaust is the first thing on my list. I was browsing through the classifieds and something jumped out to me. Why is is that the small block exhaust is so much cheaper? example http://www.offshoreonly.com/classifi...o51050-en.html Aren't they pretty much the same size and use the same material. Here is an add for what I believe is the same exhaust only for a big block. (both cmi e-top) http://www.offshoreonly.com/classifi...o31966-en.html
Why is their such a price difference?? My only conclusion is that the big blocks are much more prevalent in powerboats so why not do a little price gouging. The same also holds true for the high performance manifolds as well.

So am I just extremely lucky or what? 2005 525s with no header issues whatsoever. Boat is 100% freshwater use now since I bought it at 18 mos of age. It had been 100% saltwater use by the original owner for that first year and a half. At 315 hours should you just "replace" headers or wait for a failure? No I have not pressure checked them, not sure exactly how.
Second question is what are the brands that bolt right up? Not interested in an adapter.
Thanks, Andy

if you wait for the failure then your going to be buying a motor and headers , the 525 is a great motor and you can get a lot of hours out of them. at 300 hrs you should be changing the valve springs get new headers and be good for another 300 hrs
you are lucky to have gone this long
the hardin marine headers are a replacement
