I believe this has been discussed before. Back then, the only person claiming that exhaust gases would melt PVC tubing was Travis/WAD, so it was considered BS.

Are you sure using PVC as an exhaust tube ?? Those exhaust gas can get pretty hot sometimes . I once used a PVC t-fitting for my front exhaust and after a few months it started to warp and lose exhaust gases at the connections

PAt at x-metal has made me some very sweet thin wall aluminium side exhaust tube and exit for me at a very reasonable price. The same that can be found on Pete's and Pat's boats.

The last thing you want is to open up the back end again if you encounter problems witht the exhaust

I melted one too, but it was much further up in the system (dual exhaust T). being that the pvc is at the end of the exhaust system in his setup, the exhaust gases won't be that hot there... and he is using thick PVC.

I work at a manufaturing facility and we fit and weld exhaust all day... That would be a stronger, more expensive, and heavier option... Not sure if it would be worth it...

Excellent point Steve!
I was a litte concerned about that as well, but I have been running a PVC 90º fitting right off of the waterbox for over 3 years now, and it isn't showing the slightest sign of warping. Which makes me wonder if I'm runing my exhaust too wet???
I think if I had a tad more time, I'd have Pat make something up for me...BUT, January 13-14 is coming up FAST!!!!!! :cool2:

I had a TON of motivation from the other folks that have done this (like Raven1969), and I'm just trying to pass it on! :arms:

Got the water lines, trim tube, driveshaft tube, and exhaust tube sealed to the bulkhead. After I seal up the steering line tube, it's TOP DECK TIME!!!!

The key here is to do it right the first time:biggthumpup: As a matter of fact, I need to order some more exhaust tubes from Pat. They are really sweet and I will bet that it is alot lighter than all of that pvc you got there in the exhaust.

I use 2 part epoxy glue to seal all of the fittings and exhaust ends. I'm sure 5200 is just as good.

Cambo, let's see some pics of your build:biggthumpup: I'm sure that it will turn out real sweet too

Btw, here's a little hint about how I make some reall nice scupper tunnels. Take a 4" piece of pvc and then lay about 2 layers of 1/ 1/2 mat on top . Once cured, it is easily removed (not much sticks to pvc) and there you have some nice scupper tunnels that are lighter, bigger and easier to install

Though I can not call you out on the PVC with facts, just the labor and what you would have to do be done to fix this IF there were a problem would be painful.

Maybe you can have someone local fab something up. The hard part is already done (the design / path). I recommend local just as a way to speed things up.

I would hate to see another "fix-it" thread.

What's to fix? :dunno:
Have any of you put your hand over the exhaust outlet while it's running?
The exhaust gases are far too cool to do any damage to PVC this far down the line.
Crap, you can put your hand on the end of the b-pipe chamber without a problem.
I really don't think this is anything to worry about.
