Default Water lift mufflers

Has anyone used water lift mufflers in a performance application?

i have seen some pictures and references to the Parvey’s Black Thunder having some type of water jacketed mufflers in the engine compartment, but everything else I find is on Searay cruisers

In the '80s, my Dad fabricated a set of Stainless Exhaust manifolds for a friend's SBC powering a Volvo 280.

They were Log style, and fed into an inner transom mounted muffler, then fed to through hull ports.

It was a wet muffler system, and worked great.

Though, the muffler being 'wet', precluded the requirement for a jacketed muffler system, saving complexity and weight.

It is amazing how little water is required to draw down heat and temps when atomized a little.

Yes similar to what inboards use, “water trap”, “water lift”, not sure what’s in wakeboard I have not been in many.

something like what centek makes, not the in-line ones, the ones where the exhaust and water dump into a chamber, and then exit up and out then through the hull.

I have very, very low mounted engines and I don’t like relying on a flapper to keep water out of my engines, and I could use some more drop to help with reversion. Not trying to make it more quiet. I was considering Fabing some stainless ones but I haven’t seen them on a performance application, a lot more heat and flow than they are typically used for.

basically all wake boats have these. I have many wake boats in for service so I can snap a couple pics as well. Is this what you are asking about ?? If so watch out buying used water mufflers / box because some are cracked from not winterizing properly. Many do not know how to drain them completely.

Yes something similar to that, if you have pictures of how they run the exhaust from the muffler then out of the hull that would be great!

i am very reluctant to buy used parts these days, most end up being junk. I can’t find any that are 3” in/out much less dual 3” in, so I imagine I will be custom fabbing them if I go that route.

here one I installed not long ago and always test any new product for water against leaks. Old one had a leak so I had to install a new one. - and of course cut the necks to fit as well
