3 year old mercruiser manifolds and risers, 30 dancer raw water cooled. I run in salt stored in brackish. Winterized properly by draining water and filling pink anti.
Ran at idle all spring finally got to go out last Saturday and got on plane for about 30 seconds Engines starts bucking and losing power. Get on plane again same issue. Hydrolocked engine. Pulled plugs plugs all wet. (Put oil down cylinders after getting water out)
No water in oil. Checked under t stat for hole in intake looks solid. Pulled risers water in both manifolds exhaust section.
My buddy who is mercruiser mechanic but has no time says his engine backfired in sucked in water. Bad coil. Checked my wires last eve coil wire definitely loose. Wanted to get manifolds pressure tested can’t find any one who does it locally.
Any thoughts
