Re: Is a lot of backpreassure nessasery? (above water exaust)
Having gone thru this same thing at about that same time in my life I think I understand what he's trying to say. I don't really think he wants to become the next Jessie James but is rather looking to experiment with mechanical things. Im sure he does indeed have regard for the law or he wouldnt be asking this on a public forum.<br /><br />To answer your question Ferrariman, yes it can be done and the motor will run. Perhaps (most likely) not as good as it did but it will run. We see this all the time. But it has to be done correctly. If not, your next project will be learning how to replace pistons. Lets not go there yet.<br /><br />Someone sees a performance or race boat and its loud. They go home and drill holes and now their motor is loud. 99.9% of the time the boat actually slows down. Changing exhaust restriction is only part of the change. We mess with jetting, timing and the way the water exits the motor among other things.<br /><br />I'm glad to see some young blood interested in boating. We need more. Ferrariman, I can tell you for a fact that messing with boats, then race boats and then stock cars kept me out of a lot of trouble that all my buddies got into.<br /><br />Theres a lot of folks here that will help you. But lets start with the basics. Tell us more about what you have and we'll go from there. What year motor do you have? What boat? Whats the baseline on performance now?<br /><br />One more thing -- Look at the pic Paul posted. Then go look at race boats. Whats the one thing they all have in common? Helmets. Or more precise -- ear protection. 2 strokes may sound cool from a distance but let me tell you they are annoying as hell without ear protection when youre right in front of one. Instant headache.<br /><br />Anyway, tell us more about what you have.
