6. Please do not post to topics that have been inactive for more than 3 months unless you are the original poster. We have very active forums and any topic that remains inactive for that long should be considered "dead". It is especially confusing when there is an entirely new question posted to an old topic.

7. Posting at the end of any topic is considered to be hijacking the original posters topic which in turn subjects the topic to be closed if it continues to happen thus not making it fair to the original poster in the future had for some reason he/she needed to return for additional information or provide an update of the problem solved which is always welcomed within a reasonable amount of time frame.

8. Please note that you should see a red banner pop up near the bottom of each inactive topic asking you not to reply to old topics. The Red banner will read: Please note this topic has been inactive for 90 days. For the best results, please start a new topic.

  • Dry joint vs. normal exhaust

    Hello there!

    I have a question: can dry joint exhaust be replaced by a standard one? Is there any modification needed?

    The dry joint exhaust manifolds/risers are OEM only, expensive as hell (as far as I know)

    Thanx

    Don't see why not but why? The dry-joint is vastly superior, and while kinda $$, still cheaper than replacing an engine damaged by leaking riser gaskets. 'nutcase

      Well, I still think that replacing ordinary manifolds will prevent water damage to the engine, and considering that the dry joint manifolds are more than twice the price, it's reasonable to install ordinary ones... Especially nowadays If it's possible, that is...

      Thanx

        Ayuh,.... Without knowing just what motor We're talking about, It's kinda tough to say...
        I would think there might be some Plumbing that'll need changing, both water,+ maybe exhaust alignments,...
        Donno....
        I would dare speculate that I'm pretty sure that I could adapt a Dry joint system onto what was Not before...(doin' it)
        That said,... I'm also sure I could do a Workaround goin' the other way as well...

              Why would you be wanting to replace 4 year old dry joint manifolds and risers to begin with? The reason the old style failed so oftes was due to failure of the thin metal edge between the water and exhaust sections at the gasket surface between the riser and manifold. The dry joint doesn't have that problem.

                You got a point, but it won't be long and everyone that has a boat with dry joint exhaust will have to replace them so this issue will come up eventually

                It's not time to replace the manifolds on the boat i was asking for yet, but the customer wants to order the manifolds, so I came up with the idea....

                Thanx

                  Ayuh,.... If the dry joint manifolds last 3 times Longer, yet cost Twice as much,....
                  Are wet joint manifolds actually Cheaper,..??

                    Hmmm... do you really think it'll last 3 times longer (in saltwater) than a wet joint one? If yes, then it's not an issue anymore...

                    I guess it's too soon to ask the experienced users if it really lasts that long...

                    Thanx for your opinnions though!

                        For what it is worth - I bought a crate engine from Mercruiser back in 2003 for my boat. I discovered here on the forum that I had the dry joint exhaust system. I boat exclusively in salt water here in SW Florida with a raw water cooled engine. (And it seems we have even saltier and more corrosive water than most for some reason! ). I sold the boat this summer but never had any issues at all with the manifold or riser in the six years of use. From looking at the design - I would never go backwards - even with the extra cost involved.

                          If I was going to the expense and trouble of replacing my engine with a "crate" engine for use in salt. I would also get it with closed cooling.

                          Dry-joint exhaust and closed cooling would probably outlast you.
