So, I'm back to the drawing board. Dave at Green Water Marine Exhaust has decided that he did not want the job. He did suggest that if I were to build the same exhaust that I might try to contact the folks at West Coast Insulation and have them manufacture a some heat protection for the exhaust (http://www.wcinsulation.com/insulation-solutions/heat-protection). What do y'all think????
Hey Chris, thanks. The followup is certainly appreciated.
I chatted with Chris for awhile at the show and told him what the problem on your boat was and that I would get back to him with a link to this thread. I guess he got tired of waiting for me and took care of finding the thread himself and checking it out. (He hasn't yet commented on my mad sketch skills though).
Chris at the show.
One of their items on display at the show which would be slightly similar to what is needed to fix your system.
Sorry for the delay in responding. I really appreciate yall keeping me in mind. I will give Davis a call in the morning and update the thread with the news. The time for speed and sun is is almost here!!
Nope. Called David a few weeks ago and re-sent him pictures (I had reached out to him in August 2013) and I'm still waiting on a return call. I can't believe this is so difficult. A guy would think that folks who are in this business would be busting down the door to make this exhaust. So far that has not happened.
Yep, that's a bit high for what you have. It would be cheaper to replace the headers with wet-headers with downturns and then use the current tee's with the water in them. Two sets of new lightnings would be about half the 8G.
Ok, how about Gils as the manifolds and the gil tails, which mix pretty far back and down, and use the end of the mixed tail as the starting point for a fabricated single wall tube Y and elbow.
