    Default Exhaust advice

    Just purchased my first jet boat. 78 Python with a 460 ford. It has Bassett over the transom headers. Are these going to be a problem if I have to idle down the river? Should I consider going back to a log type exhaust?

    Thanks,

    Steve

    I have the same set up and my boat idles just fine, you just have to either give it a little stab of gas once in a while to send some water through the headers to keep them from blueing, or run a slightly higher RPM and control your speed with the gate. Mine is set up to have the steam start at around 2k RPM.

    Ideling around in a jet boat is no fun though, as they dont steer well at slow speeds compared to a pro driven boat.

    Noise does not concern me, it is the issue with the water flow. How often do I have to stab the gas to keep them cool? I dont want to loose my passengers

    That's the thing with rivers...they have a current. shut it off and float downriver.

    Are you worried about the headers getting hot and burning the pasengers? Even with the steam coming out of them I would certainly advise everyone on board to keep their hands away, as they are hot even then. If I have to idle for a while (no wake zones etc) I give it a little jab every 2-3 minutes, or like I said just pull the shifter back towards reverse a bit and use more throttle to keep the water in the headers, but your speed slow. Slow speed handling in a jet boat takes a little getting used to...

    Or you could always just put the logs back on, it might be a better option if you're going to have a lot of guests along that might be tempted to grab the big shiney exhaust header
