    A lot of noise comes back out the carb throat that you will hear with the cover off or the access door open, as there is no muffler on the carb intake like the 1957-58  35s had.

    I had a 1958  35 HP (not the super quiet one) get really noisy (like a straight pipe) when the exhaust housing cracked just below the water outlet and twisted slightly, opening up a crack about 1/4 inch wide, but you would have found that when you took off the exhaust housing cover.

    Let us know what you find.  I have several 1960s Super Quiet 40s, and none are very noisy.
