4.3 problem

[shrek]

i took my boat out today for the first time this year. got about a mile from the boat ramp running full throttle the engine just dies. checked out the engine and the exhaust manifolds were hotter than normal the temp gauge was showing 150 and the engine will just barely turn over. did it burn up need help

take out the spark plugs and turn it over does water come shooting out of the plug holes?

no water in cylinders pulled engine only to find that engine is not locked up but the upper unit is

Sounds like the Leg Water Pump wasn't operating correctly. Therefore minimal coolant being pumped to the Manifolds.
