OK, Winter time maintenance. on my '94 4.3L Mercruiser. Winterized completely (removing all the water in the motor) in October of last year. I just got through changing all the bellows (shift bellows had not been changed, and was leaking), and gimble bearing. I have removed the motor cover to have it reupholstered, and have the boat covered with a canvas trailer able cover out side. I finally got everything back together, and it would not turn over. So, I remove the outdrive, thinking it may be in a bind or something. I try and turn it over, and it still won't.
I removed the spark plugs, and water comes out. After an oh ****, I check my engine oil by the dip stick, and there is no water in it (yet) I turn the motor over, and out comes water--Mainly from the two front (flywheel side) cylinders. After turning it over I have water in the oil. Remove oil and filter, and put in fresh. Run the motor, and it runs fine, idles fine. Drain and repeat 2 more times.
All this time, running only for a short period of time without water connection checking temperatures, ( I could always touch the exhaust manifold with my bare hand during this process),and with out the out drive attached.
Now I am ready to attach my outdrive, and check for water again. My question is--IS THERE a way to check my riser and manifold to see if the water jacket has corroded through,and letting water into my exhaust side? Before I go an contaminate the oil, and motor again? Could I have gotten rain water in through the carb? My spark arrestor was on almost all of the time.
Thanks for your help in advance.
