Interesting find while changing prop

[samsdad1]

Alpha one on a Mercruiser 3.0 1997 fish and ski.

I took my old stainless battered prop off and after removing I noticed a roughly 2.5" dia X .5" thick chunk of what appeared to be black rubber that had melted?

What is this? pics to come.

It's the partial remains of your exhaust flapper (shutter) !!!

And... Sorry I am a boating novice, but skilled with tools. What to expect.

Also wanted to mention love Courtland Va as we go through there many times a year to get to the inlaws in Ahoskie.

You will have to pull the exhaust elbow and replace the shutter. It sets in the top of the exhaust tube. You will also have to find out what elses is melted and find out why you had the overheat that caused it to melt.

Thanks, my father in law had the motor rebuilt years ago and it may have been left behind. I will pull this and check. Is there a good write up on this around?

#6 and 8 here: http://www.mercruiserparts.com/Show...8.png&inbr=2330&bnbr=190&bdesc=Exhaust+System Don't know much about 3.0, but you should be able to loosen the clamps slide the rubber tubes enough to get it apart. Look for the other half.

Reassemble with alittle dish washing soap with help the boot slide back on the exhaust very easy
