525 header question......

[JupiterSunsation]

I have about 180 hours as of right now. Every year I do new impellers and housings at the beginning of the season.

No wonder that boat is so clean! 180 hours is still new! :sifone:

about $4,200 for headers per motor...

That's retail I hope. Their new replacement program was going to be alot more cost effective, so I have heard. I spoke with Stellings a while back and they thought that because of my staggered set-up, their headers wouldn't be a quick bolt on exchange installation.

I believe thats what we paid Phil when ours took a dump a few years ago.

Tech at CMI said it is time that kills the headers rather than hours......????

Dan...I'd think you and Ken would know a thing or two about this subject Looks like this fiasco has hit Ron too now.

We have a set we will be "dissecting" shortly to find out a little more..
This is the first set we have not been able to repair...one leak on another set of headers was away from all welds in the parent metal bothered me the most..in aerospace we sonically test all the raw material to prevent that type of flaw..I have been speaking to Ron, too

180 hours in freshwater on a lift in a garage. very little sun, no rain, wind or water for most of its life. It might as well be in your bathtub!

You are going to have one of those "old lady story boats." Woman inherited it when her husband died, son couldn't use it cause he got killed in the war, kept in a barn for 10 years, serviced annually, 2 coats of wax per season and they even put new tires on the trailer every two years........ She sold it cheap because she wanted it to go to a good home type story......:sifone:

He said he has seen sets with 50 hours on them shot to sh!t and seen stuff with 500 hours on them that look new......it was kind of an odd statement.

That says something about your product!!! nice!!!

That could be good news for me.

"and seen stuff with 500 hours on them that look new......"

It sounds like it may have something to do with the installations. Maybe some boats are plumbed in a way that the water flow is less, and the headers run hotter. If salt water gets a chance to turn to steam, I'd suspect that would be pretty bad on any material. Does it seem like some brands of boats using certain sea strainers have more problems than others?

I had a lengthy discussion with CMI a few years ago about this. From what I was told, the pipes made by CMI for mercury were of a different material. If you buy the headers directly from CMI, they are made out of a better grade metal

 

[C_Spray]

If so, that's another finger pointing towards Mercury...
