i recently bought a boat with a blown motor.
it had a cracked casing, small fix right?....it needs crank bearing.
well upon disassembly i found the cause of failure. millions of black beads.
these beads have pitted the #1 piston so bad it looks like it boiled the metal. they are embedded in the ports openings in each cylinder.
also all the intake and exhaust ports are 10-50% blocked by casting ridges, as thin as paper, which easily disintegrate. i am not impressed.
the motor is a 1987 mercury 70hp 3 cyl.
now what? anyone i can talk to at merc? (do they even care?)
