Well, i found the backing plates for the exhaust shutters in the exhaust ducts of one of the outdrives when I took them off last fall. So, I am assuming that the shutters are vaporized and should be replaced . . . probably both engines.
It seems that the Mercruiser part is 807166A1 (replaced by 807166A3 ??? Correct ???)
They have the 'A3' on iBoats for a decent price (Mallory brand). Other sources are upwards of $50 each, so it would be $200 for the 'twins'.
I am wondering what the life expectancy is for exhaust shutters, assuming no cooling incidents, or things of that sort ???
There are various brands (Sierra, Mallory, Mercruiser, GLM). . . I am also wondering if there is better/worse experience with certain brands that folks here have tried???
TIA for any advisement on longevity and brand preference. Engines' info in signature below.
