I have a 1984 85 HP Force engine. The insulation<br />in the cover rotted so I pulled it all out so it would not get sucked into the carbs. Is there an aftermarket isulation that I could put in to deaden the noise. Is it that important.<br /><br />Also, I think I read that the Seloc Manuals have errors in them. Which one would be better?<br /><br />Thanks
