Believe it or not ABS would be better. The melting point of ABS is 221 degrees F and the melting point of PVC is 176 degrees F.

Max temps are 176 and 158.

I used ABS after the waterbox to bypass the resonator on my doo when the great quality resonator cracked. :biggthumpup:
I ran it that way for a full season of about 50+ hours and noticed not even so much as any distortion.
I later replaced it with Aluminum and some Silicone hoses though just to be safe... The melting point of Aluminum is 660

If it helps, Seadoo uses plastic on part of their exhausts.

it sure helps my point......

he said SEADOO uses it..... id like to take this time to remind the jury that seadoo is also responsible for the 3D.

i rest my case.

mr, e.... thank you and you are excused from the bench.:woot:

youre wrong. plastic is fine for exhaust applications. thats why all exhaust parts are made of plastic.

Also, on the incoming waterlines, when you foam the ski it could be possible for the foam to collapse the lines

Not even close. This isn't line for freaking blowing bubbles in fish tanks :purr: It's quite stiff. And Jeff foams when the halves are apart. So there is no pressure on the lines.

Yup........less pressure on the lines = less chance of the heat and pressure blowing out some 5200 between line and the hull.

I believe I said "It could be possible", not it would. remember Murphy's Law, anything is possible.

brraap....thats so 2002
the front outlet on my square is mabe from ABS... its one of the fishing pole thingys......it has held up with no problems at all and belive me it gets a lot hotter than the rear outlet. i have never been a advicate for a pvc tee thats the hottest point of the exhaust and most restictive...but as far as abs goes i wouldnt have a problem using it from the bulkhead to the back.

I am currently running a PVC Tee on my square, out the side of the hull below the carb. It works fine, and does not get hot.

I run this setup because that is how Mr. Pillus built the ski, and it obviously has worked for some time.

That being said, If I was building a ski from scratch, I would not be using PVC for the exhaust but would be using Aluminum pipe.

I have way too much experience with fixing sprinkler pipes that have burst from no apparent reason to trust any sort of plastic in the foamed aft section of a ski.

note: I am not saying it will not work, I just personally would spend the extra $$$ and go aluminum.

I ran a plastic PVC t fitting back when I owned a square nose and it melted after 3 months of use . The ends where the hose mounted and was clamped collapsed and leaked exhaust in the engine compartment. It was hard to notice because the t fitting was behind the battery and not visually accessible.

Aluminium.

just so everyone is aware (and im pretty sure that royal is) there are 2 different types of sch 40 pvc one of which is refered to as "foamcore" i DONT have enough jetski experience to chime in on whether or not pvc/abs should be used as an exhaust material....... but i do have enough plumbing experince to say that pvc of any type is considered a combustible (sp?) that in and of its self would scare me a bit if im installing it in a 30,000 sealed jetski..... ill also say this ....... if your using pvc or abs dont use "foamcore" ...... if u just pick up a length of each (foam core and solid core) at the same time u will see why..... its a night and day difference

That's funny you should mention this, just last week one of my helpers was loading up 2" pipe from the "pressure" side of the pipe rack. I asked him what he was working on and he said he was going with his plumber to "stack-out" a house. I asked him why in the hell he wasn't loading up foam core, then and if he was purposefully trying to waste my money. Most guys would prefer grabbing the foam core pipe simply because it's so much lighter than standard PVC.

BTW, Jeff from WaterDawg advised one of the members here that he was using a type of ABS pipe that had a high-temp rating of 240 degrees. Have you ever heard of High-Temp ABS? I did a quick Google search and came up empty handed. :dunno:
