don't you run water cooled headers like real boats? Or is it just water cooled head?
Silicone exhaust coupler

We run water cooled cylinders. BUT the way the Zenoah is a converted air cooled to water cooled engine. They must also run a water cooled adapter to cool the o-rings that are used at the pipe to engine adapter. Our engines we build have water cooling coming from under the exhaust port around the exhaust and up into the water cooling jacket. Than dumps overboard. Water cooling in the exhaust is a massive hit in power.

Thanks, I was unsure of how it dumped out from the engine. Makes sense.

And it's funny...I'm willing to bet that where it's located makes a difference. My Bart pipe on my l5b the coupler is just fine...my dbxl with the dominator pipe it tears thru them. Ones much closer to exhaust port than the other though.

So i am trying out permatex ultra copper high temp rtv in place of the coupler. Im letting it cure now and i will report back when i have a definitive answer if it works...yes I have used it in high heat applications and it does work so hopefully I have the same luck as im really not digging the ugly silicone hose and hose clamp...makes the truck lose some appeal with that crap

Taking my junk out to see how it does. By "it" I mean the entire rig not just the damn coupling.

Just to report back...the coupler held for a good (benefit of doubt) 20 minutes. True losi fashion.
And do you dbxl owners...when you lose pins out of the axles body pins will NOT get you out of a jamb. Centrifugal force I suppose

Seems like the dbxl has a bad habit of flinging pins ?

Does a bear ? in the woods? ?. Normally not as bad as hes had it lately, but yes they do tend to fling pins out. Tbh since I've switched over to flm shafts it hasn't been such an issue.... ymmv.

You can make the pins out of partially threaded Allen screws. I think those pins are 5mm? Cut the Allen head off and the threaded part with a dremel. Then heat it to a cherry red with a torch and dip it in motor oil or water
