Oh Boy, I have extra parts ???

[70mustang]

Greetings, I was taking apart my Merc 1999 Alpha One lower unit to change the water propeller and when I dropped the lower unit, I noticed two extra parts that I can not figure out where they go. I wish I knew how to attach a picture, but they look like stainless shims. They are about two inches long, have 5 small hole drilled, one side is an oval shape and the other is straight. Has anyone else seen something like this?
Thanks
Marty

Re: Oh Boy, I have extra parts ???

those are the remnants of your exhaust flapper(s)

they are mounted in the y-pipe and fail when there is an overheat/lack of cooling water passing through the exhaust

Re: Oh Boy, I have extra parts ???

thanks guys, but I have never run this engine w/o either being in the water or using the muffs when rinsing salt water out. Be it as you say, I need to do what next. This doesn't sound good and I guess I am fortunate I am doing my annual maintenance to further damage the motor. I hope.

Re: Oh Boy, I have extra parts ???

no big problem, just install new ones

they are located at the top of the y-pipe and take about a half hour to install

do a search here to get some info/instructions and perhaps an oem manual to download

Re: Oh Boy, I have extra parts ???

thanks again. I have a 1999 Maxum with a 3.0L, Merc I/O. I also have a Seloc service manual and I still can not figure out were the exhaust flappers are. I really do not like this manual. Please advise I am not familiar with this boat beyond routine maintenance. The only thing I can figure is the water pressure to the muffs may have not been enough volume to cool the engine one time.

Re: Oh Boy, I have extra parts ???

Please tell me where these flappera are located on this 3.0L merc. Also, do you think West Marine will have them?

Re: Oh Boy, I have extra parts ???

Pull the exhaust riser (not the manifold) and it (not they as it's not a V-8) is at the far end of the rubber exhaust connector. West Marine should/may have them probably PN 18-2733. They can also be had from NAPA auto parts same PN.

Re: Oh Boy, I have extra parts ???

I think I am closer, but have a clarification. I see that my 4-cylinder has one exhaust manifold and this connects to a u-pipe that goes up and then down, This u-pipe is then attached to a rubber cupling and then to another pipe and then another rubber coupling and then out to the transom. Is the exhaust riser the metal u-pipe that goes up and then down to the coupling? if So is there going to be a gasket on the exhaust riser? sorry for such elementary questiong, you probably think I'm stupid and right now I feel that way.

Ayuh, 'n Yes....
There may also be water in it, if ya haven't already drained it...

Oem gaskets are Best...

Re: Oh Boy, I have extra parts ???

Bond-O you are the best and I have two other issues now. I removed the riser and it appears to be pretty much shot. The corrsosion inside is probably what let go of the flappers. I would feet better if I had a new riser. It has part number 12076 stamped on it. Can you recommend a location to purchase one? Also, when I took off the outdrive to grease the two universal joints. I notice they do not have grease fittings. It looks like someone screwed a plug into the threads. I can not get the plugs out. Are these sealed bearings which don't need grease. Again, its a 1999 Alpha One outdrive with a 3.0 4-cylinder engine. I heard that a any grease is better than no grease at all. thanks again for your assistance.

Ayuh,... You can poke around Here,....

The u-joints probably are non-servicable, they make 'em that way now-a-days....
If replacin' 'em, I believe you can still get greasable joints...

...I also have a Seloc service manual and ....

:facepalm: (Seloc = hand wipes, toilet paper, or fire starter, NOT a service manual!)

Download these for the real thing....

At 12+ years old I would be very surprised if that riser was serviceable. They are usually replaced at about 5-8 years....
While you have the riser off, have a good look into the water passages in the manifold, I would even take the end caps off (if you have end caps, some manifold are single piece)....

Re: Oh Boy, I have extra parts ???

I have ordered from here with good success. Like Chris mentions, be sure to check your manifold as well. You can search the site I listed for prices on their manifolds as well.
