It kind of reminds me of the exhaust set up on my wakeboard boat. The nortech is cool seeing it idle into a cove and you can't even hear it.

Terry,

Are you doing this on your V-bottom boats also or just the Cat's ?

Didn't RICK Sr (RIP) from INNOVATION come up with this like 10 years ago on the INNOVATOR? I mean really this isn't "NEW" technology much less created / invented by Nor-Tech. Let's give credit where it is due. Just my $.02

I was referring to the Superhawk 34, which I believe is a Don Shead design, and is normally fitted with 315hp Yanmars on Bravo 3's .

Yes to an extent that is true and it was used on the Nor-Tech 380 "Innovator".
It was also an underwater exhaust but that's about all it has in common with what we're doing now. Basically the exhaust was routed down to a collector box at the aft of the bilge and then would exit down into the notched transom. Unfortunately about the only good thing was that it was quiet.
Two major problems:
Since the exit was down thru the bottom of the boat,
there was no relief for the exhaust and caused significant back pressure. A 24V starting system was required. The other problem was whenever the boat launched and landed there was again so much back pressure that the engines would bog down and lose all throttle response.

I don't think anybody can take credit for underwater exhaust being "NEW" technology. What we did was come up with a new and unique way to make it work without any of the negatives.

Terry, have you tried this exhaust set up on a V-Hull with a Bravo style drive yet?

I dont recall them saying it was new to the world. It is new to a 36 cat. Delo had a need to stop from being kicked off the lake and Nortech answered it. Great going Terry and crew.

Sounds like a great setup, i love quiet, nothing drove me nuts like driving around with a noisy CAT 3126 about 12 inches from my butt. The guy who designed the exhaust on that thing was the dumbest human alive. He managed to create a perfect resonance at idle and cruise speeds, it was absolutely painful to drive that stupid boat.
