mercury 115hp help

[1986bassbuggy$@]

I have a 115hp mercury 88 model that I think slung a rod is this motor shot completly it will still fire up on a dime but knocks and there is a hole in the intake manifold is there a chance that maybe the arm on the cylinder came apart or something? I thought if it slung a rod the hole would be in the block?

Re: mercury 115hp help

If the bottom of a connecting rod broke loose, it can easily exit the crankcase cover. Normally if the crankcase is damaged, the motor is toast. If the damage is confined to a single connecting rod and the crankcase cover, you may be able to pick up a used cover and new rod and try to repair. The crankcase cover is matched to the block, so it may not work....
