Slip in silencer = warmer exhaust water???
Just picked up a set of these as I wanted to quiet the boat down before the weekend.
http://www.hardin-marine.com/p-12622...-silencer.aspx Put them in, run the boat on the hose and they quieted the boat down significantly. Let the boat run for a few minutes and the exhaust hose seems to be getting much warmer than normal. So, I let it cool down for a few minutes and remove one silencer. Shooting both side with my infrared gun the muffler side is getting up to about 180-185* and the non muffler side about 130-135*. The top of the exhaust is running about 20* different as well. I called Hardin and they said it was impossible as the slots were a larger area than my exhaust diameter. To me it seems like the water could "bounce back" and stay in the exhaust hose longer and in turn get hotter? I have to assume that 180* is creeping up on the limitations of the hose? |
In my experience...Those mufflers drastically reduce horsepower as well.

Chris The plan was to try them out and if I lost rpms/speed then drill a few holes in the baffle for a happy medium. I dropped 12 decibels with them so if I dropped 6 but lost little/no speed I'd be happy. But the warm exhaust has me concerned. |
