Service manual states:
Position gasket and bearing housing on gearcase.
Apply OMC Adhesive "M" to surface of bearing housing and position impeller plate over bearing housing."
I read this to mean there is no adhesive applied to either side of the gasket, but there is on the top of the bearing housing to seal between it and the impeller plate. (metal to metal fit). Correct?
Seems like there would be adhesive applied to the gasket and not between the metal to metal mating service between the bearing housing and impeller plate. If that surface needed sealing I would think a gasket would be there.
Thanks in advance for your input.

You read it correct. What the service manual says is what they mean. Personally, I add some OMC gasket sealer to both sides of the gasket. Probably not necessary, but won't hurt, except to make the next guy cuss when he takes it apart.
