I found two of these in one of my parts boxes today. They are
identical except for numbers. The first one (if we are talking
ascending order) has 2727 then a diamond with FP in it then the number 1

The second has 2727 then a diamond with FP in it then the number 2

The centre of #1 has 87 in it. The centre of #2 has 88 in it.

Both have 333854 on the other side of the raised ring.
The rings appear to be raised in the middle with the outside lower but
they are actually recessed in the middle, like something could stand
in them or the could go on the end of something??

They are a lightweight metal of some sort. Clank when touched together.

I cannot work out what they are/do/are used for.

Any ideas?

Not knowing their size, I could be wrong but it looks like they might be used
on a transom for a small outboard motor's threaded clamps with the pivoting
washer on the end to fit into so it doesn't mar the GRP??

How big are they?

Do they look like anything on your engine?

They are exactly 3 3/8" long and 2 1/4" across.
1/4" thick.

What has me most confused is why they are sequentially numbered.
Or why 87 then 88 are important enough to stamp on them.
And 2727 1 then 2727 2

An engine part would make some sense but I can't see why they
would be closed. IE, they remind me of the same shape as my
engine exhaust manifold on my Toyota Hilux 4WD but those would
have to be open to allow exhaust gas through, not closed.

They would certainly fit the bill for that purpose. Maybe I should use
them for that and stop cutting into the resin board I have?
I can't see why a manufacturer would go to the trouble of numbering them
just for that, though.

It's very unlikely that they are transom protectors even though they
might work in that role. My guess would be some sort of engine part:
possibly end caps for a heat exchanger, covers for an
inspection/adjustment port, or some such. I kind of recall seeing
fuel injectors on some engine or other that were covered with a piece
like that.

If you really want to know, throw them out. The day after you do
that the usage will not only become obvious but critically important.

I'm leaning towards that. I've been through the Yanmar manual and while
I can see things that are the same shape, all are designed for
something to pass through, so the middle is open.

I was trying to find something that needed them put in place while
parts of the same shape were removed for servicing i.e. that they
are not operational parts but temporary. No luck so far.
Of course, you are absolutely correct on how to discover exactly
what they are for. I'll just chuck them overboard and see what
breaks down.

Hi,

They might be sacrificial annodes? If they are made from zinc / zinc alloy ?
Could be ones from inside a heat exchanger / marinising exhaust cooling
manifold?

Just a thought??

Cheers,

Gary

I reckon 87 and 88 are the respective years those parts were made.

How old is the boat? Any equipment that likely dates from 1987 or 1988 or earlier?

The numbers do not look like the usual form of a Yanmar part number.

What pumps (bilge pumps, freshwater pressure pumps, waste pumps, etc) are on board?
