1973 25 hp water in cylinder

[clancy1010]

I just got a 73 25hp evinrude on the back of a pontoon boat that has been sitting for some time. I had no spark and put in points and condenser. This fixed my spark problem. I put in back on the boat which is in the water and got it started for about 15 seconds. Then it quit and will not start. I pulled the plugs and I notice water in the cylinders. I am in WI so I am some what concerned about a possible freeze and break. With the motor being on the boat water should have drained out of the motor the last time it ran and not need any winterizing correct????? I am doing a compression test right after I am done typing this and will post what I find.

Bad head gasket-warped head? Remove head, get 1 piece of emery cloth, lay oit on a flat surface (glass works good) Move platge, casket side down in a figure * motion until flat. Reinstall head with new head gasket and torque head bolts to spec.

Drop lower unit and inspect/change out water pump impeller. Just to be on the safe side.
