In anticipation of requiring a bit of engine sound proofing I approached a local plumbing supply shop for availability of sheet lead. They had it in 3/16 at $4.something a pound. With the measurement given the cost approached in excess of $450.00. As the engine space is not 100% contained it was an attempt at containment. Following I visited NAPA and purchased a roll of Thermo Guard. A mix of aluminum and fiberglass appearing product advertised to address heat and sound. Were there any trawler owners who are familiar with this product or a similar material?
