vibration in sole/bulkhead from engines
Posted: Mon Jan 23, 2012 10:52 am
I am trying to be careful, and not call it engine noise or engine vibration, because it is the vibration in both the cockpit sole and aft bulkhead caused by the engines.
I've noticed between the innner and outer skin on the bulkhead is sandwiched sections of poly pipe insulation to deaden the sound/vibration. Has anyone injected expandable foam insulation into thse areas? I don't think placing gaskets on the transoms where the engines are mounted would make much difference. When somebody heavy stands in the middle of the cockpit, the sound lessens. and when I push against bulkhead, this also occurs. I guess I could hire a heavy guy to stand there all day while leaning forward, but looking for something more reliable.
Thanks,
