Will this fit my 1989 5.7 Mercruiser exhaust 3'' y pipe opening?
Yes, we have verified that this will work with your Mercruiser motor.
I have a 1979 V8 Merc with Alpha One outdrive. Am I buying the right shutter?
Alpha One outdrives didn't begin until 1983 or so. So for a 1979 we cannot look that up, we would need engine model along with serial number to look up shutter.
Is this listing for a pair or for a single shutter?
This part number is for a single shutter, not a pair.
Will this part fit inline 6 165hp mercruser?
Yes. This water shutter works for several different Mercruiser applications, including your Inline 6 165 horsepower motor.
Will this fit my 1990 7.4 Mercruiser exhaust, my old ones dont look like these ones.?
Unfortunately, this shutter is not compatible with your Mercruiser motor. Feel free to post a question on our Forum page to find the shutter you need:
