Hi, I am new to the site and hope I have poasted this on the correct forum. I would like to hear from any 2000 or newer Tiara 400 espress owners. I am interested in learning your opinions on the under water exaust, mostly on its ability to reduce smoke and soot entering the cockpit. I am considering a 2002 400 express and the big hang-up I have is from my experience on an older boat with the side exaust. The diesel smell and smoke was a big problem for me. Hopfully the re-design of the exaust helped this problem.
I just finished a short block replacement on a 400 tiara today 3208 cats. I started it today and did not notice any smoke in the cockpit. Full sea trial will happen monday Ill have a better idea how it does as far as exhaust in the cockpit then. Just to confirm the exhaust system is similar. It has a water lift muffler with raw water exiting the side of the hull near the front of the engine room with the majority of the gasses going to a under water venturi at the stern outboard.
