I have a 1990 welcraft with the 5.7 alpha. I took it out for the first time this year and about 20 min into it I herd a loud clanking so I ran it slow . the clanking kept going and then the engine shut down. not a bang shut down but a smooth shut down like turning of the key. oil in engine still clear but oil in bilge milky and smelly. any help

Not exactly the best way to operate boat.
Can be a seized engine or seized outdrive

Oil level was full and new Gear lube was ful and new. All good . And the engine still turns over . But won't start.

The oil level right now is full and clear . Not black at all in the pan. The only oil is in the bilge. But when I was towed in the bilge was dry. It took two days for the bilge to have some milky oil in it.

The only other loud clanking if from a stuck valve, broken rocker arm , bent pushrod, pulled rocker stud. Pull the valve cover and take a look

It's at the shop. Still a full level oil oil engine. I looked at everything when the valve cover was off and no damage
