Exhaust Water Shutter Missing - MERCRUISER 3.0LX

[rstier]

Hi,<br />I have a 1993 Mercruiser 4cyl - 140 Alpha One 3.0LX. I noticed the water shutter was missing from the exhaust elbow. I only use the boat in a lake, so what's the consensus on needing to replace this part? Am I safe without it?<br />Thanks!<br />Ron

Where did it go? Take a good hard look when you have the drive off....The exhaust shutter is only really necessary when you shut the engine off under extreme conditions....However they are so cheap that I would replace it....JK

Ayuh,........<br />Cheap Insurance.........<br /><br />I Too,... Would be More Concerned with Where did it Go..............<br /><br />Hopefully,.. You won't be looking at something like This,.......<br /><br />

<br /><br />It's Hard Enough to make good power with a marine engine,...........<br />It's Really Tough,.. When the Exhaust is Blocked.................................

The exhaust shutter is a LOT cheaper than a new engine. <br />Do You Feel LUCKY? <br /><br />PS: There is No difference in the shutters between lake, river, or salt water boats. They all have them.
