Has any had any experiences using/installing a through-hull exhaust system on a 3.0 OMC or similar?<br />I know is may seem silly to do this to a 3.0, but I am trying to maximize what power I have, and wouldn't mine making it sound a little "bigger" in the process. The 3.0 gives me the economy that I like, and has adaquate power for my wakeboarding needs, but it would be nice to free it up a little.<br />Where can I find the supplies needed? Is there anything to beware of?
