Two days ago I removed all of the old engine compartment sound insulation. It was coming loose and had nice carvings in it from the water pump and alternator...since when we bought the boat (1,000 engine hours ago). Today I installed the new sound deadening material so it is finally fixed!
The part that is down against the table (most boat maintenance projects involve trashing the "dining room") is where the steps are, and faces forward when the cover is installed over the engine.
