Your engine is a Gray Marine Model " T".
They were mfgd about 1911 to 1920.
Engines were Gray's top of the line and most expensive two stoke
marine engs. They were a true Two / Three port design !
Had no oilers, mixing gas and oil was just discovered. They were available in
one, two and three cylinders.

Model T's used a Krice Carburetor, later engs show up with Scheblers.

If the drip oiler was original to the engine you probably have a 1911-12, by 1913 drip oilers were gone.
It's very possible that faintly etched in the face of the outer flywheel rim is a serial number ( hard to find especially under a coat of paint ) if you can find it post back here and I can date the engine !

Harry, on your Gray marine engine article the catalog engine photo is a Model
"R" it was first marketed by Gray in 1908, you can see that the engine is two castings- the cylinder flange bolted to the upper crankcase.

Your engine that shows the rebuilding is the very first Marine engine that Gray designed and manufactured, it was a single casting cylinder and upper crankcase one piece.
This engine was sold by Gray only in the year 1907, and never given a model number only marketed as a 1907. There are a very few of these around compared to the later Gray marine Two strokes.

This is a 1907 Gray Co. illustration and information, you may copy as use it if you choose to !

Yes that is the valve I was talking about mine is just a hole that is not threaded
I am thinking of making a plug machined to port water back to the water supply
Thank You for the photos Bill

Photos touched up. This free program is excellent for photo editing. Or if you just want to use the MS Paint that comes will windows: https://r.search.yahoo.com/_ylt=Awr9CMqnSsZajEkAcq8v7olQ;_ylu=X3oDMTByM3V1YTVuBGNvbG8DZ3ExBHBvcwMzBHZ0aWQDBHNlYwNzcg--/RV=2/RE=1522973480/RO=10/RU=https://www.youtube.com/watch?v=wUKMIi0mInc/RK=2/RS=mmHYIUf6.BmrEsO7bnI3MpR6dtU-

I have the same engine, very nice quality unit with a counterbalanced crankshaft. You're missing the cylinder head cap obviously, but if you want dimensions I can get you those. A metal spinner could make you up one out of brass or copper I guess. The originals were just steel, which wasn't the greatest choice for salt water, though it dents less easily.

There was a cast iron cover over the water pump gears originally. Can get you dimensions of that too if you want.

You've got the engine tag or did someone steal that?

Lots more photos and info on these over at www.oldmarineengine.com Just do a search and you'll see.
