water mixing with oil during start up proceedure
During spring start up water mixing into oil. I'm aware of the need to turn off water intake while cranking over engine to start up. Yesterday on land with no water being pulled into exhaust engine started up nicely and we ran for about 30 seconds. Shut engine down, attached water intake from bucket (not directly from hose) and cranked engine over maybe 3 times for 5-8 seconds each time, engine didn't start. Checked oil and water had entered block emulsifying into a thick milky white texture. This same thing happened last year during spring start up but we thought because we had water running through system and cranked over to many times attempting to start. We flushed out oil as recommended by changing multiple times and with boat in the water started engine up and it ran well all season. At the end of last season we winterized including flushing fresh water through the system and again changed the oil.
Any thoughts as to why we are having this problem during spring start up on the hard?
