- Attention powerboaters (and sailors with inboards)...
-
- My recently installed Perkins M20 is a wonderfully
- smooth engine, but speaks rather loudly in a deep
- baritone. And it's installed in a boat (an Olson30)
- whose acoustics are similar to those of an oil drum.
- So, even though the engine box is insulated everywhere
- but under the engine, a good deal of noise permeates
- the cockpit when underway. I noticed the other day
- that as I moved my hand toward the air intake, the
- baritone noise diminished. The intake has no air
- cleaner or silencer, just a grate in a roughly 1.5"
- square tube. What's involved in fabricating a silencer
- and what are the chances that it will do some substantial
- good?
-
- Thanks,
- BILL COURINGTON
