Found this the other day, may have come from this site. I know less HP motor but still interesting exhaust test. Coming from the Bike/Car world we have always been big on exhaust tuning. What goes in has to come out.
Anyway as for the maybe other issue, that sucks. At least you should be good at pulling your motors Tim

Wonder what would have more to see. Marine kinetics R&D department, or Mercury Marine's. My guess is multi million dollar operation, might be a bit more advanced, than a kitchen table, a laptop, and sitting in on a seminar once a year at PRI.
Bob used to love bashing mercury engines to me on the phone. Sorry, but 90 percent of people who have mercury power, are out boating. Not spending weeks on the dyno trying to figure out why their drop shipped parts combo isnt making the power it should. Or , if they do make it into the boat, its a crap shoot if its gonna stay together for 100 hours.

Sounds like Tim has multiple small issues with his combo......with the question of reliability #1
What's sad is the so called professional he worked with to design his build and order parts from was well aware what parts Tim was re using , what requirements the build needed to be designed around, and even Tim's budget.
I bet if Bob sold exhaust he would recommend it more often............

Maybe the limitations were reviewed, maybe not. I wasn't on the call when it was spec'd. :-)
