I used the product from Sailors Solution and have been very happy with 
the results.. I bought Time A Weigh in the fall of 06, and brought the 
engine covers home and added the insulation over the winter.  I have 
never heard the engine without it, so I cannot attest to the amount of 
noise reduction...   Hope that helps..
