Hello All; I just bought a 1976 O'day 30 with a 2 cylinder Yanmar diesel. Having owned a Bristo 30 20 years ago, I can anticipate the racket that engine will make in the cockpit. However, I can't, for the life of me, remember the name of the company that sold foil-lined (foam-type) insulation material for the engine compartment of the Bristol. If anyone has had any luck with reducing the racket of the 2 cylinder Yanmar, I'd be delighted tohear from you. Thanks hcmcs
