  • sound deadening

    I have a 221 mako with a 200 carbed merc. If I add a splashboard made out of starboard across the transom will that lower the engine noise appreciably, thanks

    I doubt it. The primary source of noise is from air intake and mechanicals and the starboard won't have any sound deadening properties.

      Does your engine cowling still have its foam sound deadener intact? this helps with the droning noise. also check for loose bolts and fasteners. Make sure the hood is latched tight and adj. properly. Hope this helps. dave.

        I recently removed the old foam insulation and replaced it with some better insulation. It helped I am trying to think of other ways to deaden the noise.

          Build an engine cowling similar to the ones many of the south florida guys use. I have been planning on building one for my boat.
