Elgin 2hp, can water cover the exhaust grid?

[Texwing]

OK, after all the effort to get the 1958? elgin 2hp air/water cooled outboard to start, its now time to build some sort of engine mount on a coleman canoe for a river trip. This canoe does not have a transom, so I will build a mount to hang over the rear side, no problem. I can make the mount however I want to optimize the leg depth of the outboard. This little elgin has the cooling tube, and then an exhaust grid of holes perhaps half way down the leg. Is this grid of holes supposed to be underwater (quieter I suppose) or above water, or ?

I do not have, and have not found, any online manual or books on this engine, so mounting tips would be appreciated on how high off the water is optimum for the engine. thanks again to all those who have responded.

I would think the only limitation would be good prop action and low enough that when steering the prop doesn't strike the canoe.
I aften wondered if it has 360 degree reverse could you beef up the side of the canoe and just clamp it on? Also maybe mount the motor about 2/3 of the way back instead of near the stern.If your alone the boat might balance better.

All true, I cold just clamp the motor to the side of the canoe but there are many areas of shallow water and should the motor hit the bottom it will not pivot backwards, only sideways, so I am afraid I could damage it. I am trying to come up with a transom mount that is movable if I am alone in the canoe, so it will balance better at least when I am alone.

The exhaust relief holes are just that--exhaust relief holes. Putting them underwater makes it hard to start because the exhaust back pressure is too high.
