Hi Jim, I've had these problems before. I turned one car into a submarine TWICE and resurected it once (the second time the water in the cylinder bent a rod and although it started, it knocked bad). My boat has gotten water in the engine from bad shutters, or, because the exhaust elbows are not high enough above the water line (haven't figured that one out yet).
If you haven't gotten the water out of the cylinder already, that should be your first priority. The easiest way is to turn the engine over by hand with a wrench on the harmonic balancer bolt if necessarry. Taking all the spark plugs out would make it easier and you're putting new ones in anyway. Turn the engine over a few times by hand and that will force the water out of the cylinder thru the spark plug hole.
Aternately, take a small hose that will fit into the spark plug hole, and tape it into the suction end of your shop vac hose and suck all the water ourt of the cylinder. I have to use this method to suck diesel out of the cylinders of my truck engine when I changed injectors and got diesel in all the cylinders.
Next, check your engine oil, power steering fluid, tilt/trim fluid, ect... for water. Change if necessarry.
Now, if the starter is dried out. Try and start the engine. It should fire right up. Idle it for a while to dry it out good.
Good luck on the starter still working. If it wasn't submerged long, maybe it is still good.
My main concern would be to get the water out of that cylinder and get it dried out before it rusts/corrodes.
