Since I am asking question today I have another one. We have a small boat 15' with a 1988 2 stroke 75 HP Mercury outboard. The engine is so load that the wives often don't want to go boating because of the noise. Is there anyway to dampen the noise to a more acceptable level. I was in a friends 70HP Mercury of about the same vintage and it was night and day, his was relatively quite while mine was extremely loud. Any ideas what might be going on or how to dampen the sound. <br /><br />Claude
