how do i quieten it?
I have a 5hp 2 stroke evinrude outboard that i use to push my 14'
catamaran along when conditions are too dead or too hairy to sail it.
its reliable, doesnt smoke, starts on the second pull every time, uses
little gas and seems to take sal****er in its stride, but its as noisy
as anything, and i say this a a bike rider with almost open exhausts.
Noone could love such a sound. how can i quiet it, even at the expense
of a horsepower?
