two summers ago, I replaced inboard in 1992 proline with chevy mercruiser 350 vortec and installed new risers and manifolds. engine ran fine all last season. after the winter break, ran fine on muffs; launched at boat ramp (saltwater) next day and wouldnt start or turn over. pulled plugs and found water in all 8 cylinders and bottom of both manifolds and both jackets were full. this is a new engine (120 hours), any help appreciated.
