2001 captiva 4.3 inboard outboard

[firefightermoses]

started my boat the other day and at first it didn't look like I had any water coming out the exhaust after a minute or so water started flowing but it also sounded louder than normal. as I went to look at the engine milky water was coming out of the air cleaner. can someone tell me what is blown. I've been told the exhaust could have been clogged up from dirt dobbers, water pump bad, to intake cracked to just a blown intake gasket or head gasket. the motor still ran ok before I shut if off. HELP NEEDED

How was the boat winterized last Fall? From your description, it sounds like freeze damage to the engine.

please describe exactly how you winterized it last fall.

Either cracked intake or block...the newer 4.3's are bad about intake floor cracking from freezing.

Probably intake, don't let the water sit in the motor, pull the plugs and suggest go ahead and pull the intake.
