Apparently bilge pump failed over winter (yes battery bank was intact and charged) and caused bilge to flood about to level just below the carb (late model engine). All oil in crankcase was replaced with water. First question is where would water get in since oil stick is at top of engine. Engine lays just about level flat and has no slant. Oh the boat is in the hard for the winter. Cover of tranny intact and water did not reach that height. Took off flame arrester and no sign of water with a few drops of oil at the oil ring. Have not removed Zenith to see if water in the bowl. When I checked oil level was about 2 inches above full on the stick but oil looked good and when I pulled the stick no sign of water. Next I took hand oil pump and inserted suction line in the oil fill at front of engine down Into the crank case and with first pull of pump was water. Pumped until sucking air and all I got was water. Checked tranny and no oil or water.
So how did water get in and then where would the oil have been pushed out of engine since oil floats??? I am assuming that what is left in the crankcase is the oil that I saw in the tranny that is now in the sump of the crank case.
Have not turned over engine, checked plugs and no sign of water, engine was fully drained, installed RV antifreeze, via T-Stat until it flowed from the drain ports around engine, left t-stat cover loose over the winter. No excess oil in t-stat recess just the usual stuff.
So is the drive shaft where it exits the tranny not sealed. I am baffled and need the community of big propellers to chime in. I have clicked around the forum but can't see a related post.
So assuming water just seeped in and flooded the crankcase can I remove the last vestige of bulk water, replace with oil and fire the engine up, then do multiple oil changes until clear (not milky). OR am I in the market to rebuild. Not the answer I want but it is what it is.
Thanks to all her have read this long post. Boat is a 1964 Columbia C40 with a rebuilt A4 about 10 years ago. Ran greAt with no oil or overheating issues so good bones.
