Engine room insulation clean up - more screws - 2011

It seems 50 screws and washers are not enough for securing the sound insulation in the engine room. Looks like another 20 or so will be needed.
January 2011 - Currently At Marina Cortez Harbor Island, San Diego, CA

 We used a drill bit with a stop on it at about 1 ¼ inches. That way we would stop at ¼ into the ¾ ply wood and not worry about hitting a water tank.  We probably put too many screws in but places like behind where the new water muffler goes will never be able to get at again to do this, at least easily.

Too many will not be a problem, not enough could be. So another trip to Unitedfasteners shop will be in the works soon.
