F9.9SJ Water Seal/Damper

[Fastfred]

I need a little help on installing water seal/damper on the upper casing?

[99yam40]

what kind of help?
I have no idea what motor that is so I cannot look up the parts diagram.

Boscoe might be able to help, but may need more info also

Upper Casing Water seal/damper

I have attached a picture of the upper casing when I removed engine to inspect seal, the drawing callout a Damper water seal, but I found no seal there, yet I ordered seal and place on top and that seal wont allow motor to rest flat? I hope picture is attached, I am new at this forum, sorry but I need help?

[99yam40]

what year is this motor,
and what is the part number of the part you are trying to install?

1986 9.9HP Yamaha

I have oil and water mixture leaking from outboard when I run it, that was the problem when I purchased motor. Again the picture is what I found when I removed the motor., but I think there should be a Damper water seal based on parts diagram, the arrow point to the place where I think the damper should have been, but there was only this shinny looking bushing, I hope I am making since to ya'll?

FOUND IT, PART #4:

If that's the correct part, does it appear to be a "compression" style gasket? If so, it may very well sguash down once assembled..

As for the other parts, look at the parts diagram (on this post) and compare to what you have.


99Yam, can you blow up the pic, PB won't....

I am guessing you wanted this pic bigger
this is the best I can do, and I believe it did not work.
both ways I tried it

[dray0151]

See if the attachment comes through.

[TownsendsFJR1300]

Little better...

Is the new part you bought from Yamaha metal? If so, does it look compressible?

And do I understand there wasn't anything there before?

Picture

I hope this picture show a little more, the seal has a metal sandwich between the rubber, looks like if I take that bushing out the seal sit lower and at same height as the other rubber seals/orings.

[Fastfred]

Seal on Top

This is a picture with new seal sitting on top of that bushing, it is too high profile, maybe the bushing was an old design that lost the rubber, I am lost.....

[TownsendsFJR1300]

Pic is still small but no biggon..

That seal, looking / and especially your description, WILL SQUASH DOWN when you tighten the block down.

It needs to fit tight or it'll leak. With the metal in the middle, it holds it together (helps keep it from bulging).

The old one, with THE RUBBER MISSING (blown out, what ever) IS why it was leaking.

Your good to go, at least with that seal.. Tighten her up!

As noted earlier, check the parts diagram and make sure you have everything you should.

Plz post back with results.
