TRI CABIN UNDERWATER EXHAUST SYSTEM

[rbcool]

I mostly love mine as well. People are Amazed while underway we can hold a perfectly normal conversation without raising our voices.
One thing I've noticed is the port side does rumble and shake pretty bad @ 1100 - 1700 rpm. I'm thinking the "pan flute" on that side needs to be removed and completely cleaned.

ok ...now I see a real down side to this system...without the sweet sound of 2 454's behind me ...I'll not have the excuse of ''I can't hear you dear"..but I'd love to find a way to do it to the gen-set..

Is there some kind of safety check valve or flapper in there or is it like a Merc outdrive, torn bellows = sink?

NEWS FLASH -- THIS JUST IN: Having gone where no man has gone before (sorry Aaron), I can attest that there is no flapper, BUT there is a bronze tube that is part of the clamshell mounting plate that extends to about the top of the highest bump in the bellows shown in Sir Aaron's "ultra close-up". This, not coincidentally, is just above the LWL. The deal is, the butt-ugly orange clamshell that serves as the exhaust eductor is mounted to a plate on the hull. To this this plate is welded a tube that extends about 8" up inside of the bellows. A piece of exhaust hose goes over the metal tube to act as a washer between the metal tube and the bellows. My bellows are in my truck bed at the moment (full disclosure, my boat is on the hard NEXT TO AARON'S!) They look so dang good, that I'm considering not replacing them (searching for replacement bellows is how I found this post). Pictures at 11:00 (OK maybe in another week or two) I'm replacing the underwater exhaust backing plate on my port side (with waterjet-cut 1/2" fiberglass sheet!) Look for an extensive post after I complete my latest project....


True or false: The location of the former Whittaker Corporation off of Route 30 in Lancaster, PA, where many of our boats were born, is the site of a Superfund cleanup project?

i had the honor to hang out with perry and his son on saturday and sunday last week. in a true display of TROJAN POWER, i't is amazing to see two tri cabins side by side. (will post pics soon). as for the underwater exhaust system. i was amazed at the design, the simplicity and yet the functionality of the whole set up. i'd LOVE to find out who at trojan came up with this. i have some great pics, and, not to steal perry's thunder, i'll post those too. when you look at the design of the 'water jet' system, it sort of looks like a stingray. and the whole assembly is HEAVY too. really heavy duty design and construction.
