    fish finder install and engine cover insulation-gctid399252

    installed a new fish finder (humminbird pirhanamax 170) and insulated the engine cover with blue magic rubber in a can, used 2 cans and then coated it with 2000 degree high temp paint just to be safe

    just thought I would post the results of the extra rubber insulation on the inside of the engine cover. I had read other places people saw a 30% reduction in noise after they did this. It definitely didn't make that big of a difference, but I would say 10% reduction in noise is accurate. I'm just trying to get the boat to wear people can sit in the rear seats and be able to talk to each other (when the boat is up over 3k rpms) without yelling. It went from me not being able to hear what people were saying to me from the back of the boat to me being able to talk (albeit loudly) to other people in the cockpit.

      Gasket sealing the edges has helped some members.

          That's not always a bad thing.

          Im going to try that stuff on mine. Mine does have some insulation and that shiny stuff, but it doesn't go all the way to the edges.

          Also, there is a big gap around the top and sides where it goes against the transom. The angle of the cover is slightly different than the transom. So I might try to find some foam or rubber seal that will go there, if that gap isn't necessary for air circulation needs.

            anyone tried doing any modifications to the seat cushion backs on the driver side read seat? there are just open holes behind them going to the engine compartment and that could make a big difference, but putting rubber spray on the back sides of the seats could be a problem because they need to breath when moisture gets inside them. any ideas or experience?
