Small knocking noise in engine.
I have a 2002 75hp Mariner outboard engine on my rib which got caught on a rope from some lobster pots. This nearly stopped the boat dead in the water but it released again and it d'idnt wrap around the prop to best of my knowledge. After this a small knocking noise developed in the engine. More like a loud ticking noise. This is present when the engine is in neutral and in forward and reverse and increases and decreases according to reeves.
Just wondering what damage this may have caused.
Any help much appreciated.
