I was given 2 of these rather heavy red rubber items. they attach to
the transom with bolts or screws. They direct the exhaust flow down
into the water. They are cut at the bottom at an angle. and have a slim
profile where they enter the water. They must be over 15 yrs old or
perhaps even much older.

Has anyone ever seen these and what about a pee hole to see if the
inboard water pump is working? Someone drilled two holes in them for
this, but I was thinking of plugging the holes and running a slim
polyethylene tube out the back to make sure the water pump is pumping
water.
Or possibly running a tube thru the transom and thru this hole that is
already there.
Any thoughts?

found out what it is.

patent number is 3162171
