About LinkBacksI have some some silicone couplers I want to use for the exhaust it says it can stand temps up to 500 deg. Am I ok using them on these manifolds.e
how hot do water jacketed exhaust manifolfs get ???

Have you ever touched your exhaust while motor was warm? I know i can touch mine without getting burnedOriginally Posted by corbin5754

are talking about the silicone couplers like what are used on boost tubes an its not the outside temp of the riser you need to worry about its pretty hot on the inside wear the exhaust flows an if water ever goes a little lean for some reason it burns up the std couplers i burned up my imco couplers real fast when i leaned out on water one time oopsI have some some silicone couplers I want to use for the exhaust it says it can stand temps up to 500 deg.

I can touch um without getting burned but its still hot. So my guess is they should be fine them 500 is pretty hot and with water running thru them should never reach 500 deg.
If you ever ran dry (blown impeller) it would not take long for it to reach that kind of temperature if you were running at cruise speed.
I run them on mine, no problems yet. I haven't lost an impeler with them yet either
You won't lose a impeller from using them an I'm sure they will work but for any reason you lose water flow through exhaust you will not be able to catch it befor it smokes the silcone when you are out cruising or wide open the std ones don't hold up to that either but the std ones can live longer under higher temps an when you do burn them. Now we sprung a leak captain lol
Ok sounds a little border lined. Here they are I just got them installed. I'll Prolly switch them out with something more high temp. Resistant. What temp does the icmo couplers hold up to.

I don't think he's gonna lose the impeller....His is aluminum and 9" in diameter.....
It's actually ss impeller, but why would I loose my impeller any way I'm only pushing 50 mph.I don't think he's gonna lose the impeller....His is aluminum and 9" in diameter.....
I could be wrong but from what I have read these silicone couplers hold a higher temp then black Rubber exhaust hose.
You may be right i had burned a hole in my couplers be for an i was going to use the silcone ones from the simi shop but then talked to teage marine an they said dont run those just get the exhaust hose from imco so i did that an bought extra ones so i say F it run em see what happens they may last for ever i will say one thing the blue silcone looks alot cleaner
I still have my black rubber hose so if these silicon couplers burn or melt I can just replace it with a piece of my rubber hose.
I do know that at about 30 lbs of boost can reach up to 350* before the aftercooler with a pumped up diesel motor and the silicone hose couplings last for years
