Good morning folks, had s slight problem on Sunday evening my 1978 35hp Johnson made a slight grinding noise before coming to a complete stop and stalling when I tried to pull it over to restart it the head wouldn't move (it does move but only about a centimetre would I be correct in suspecting a crankshaft bearing has gone? My mate took both plugs out and peering inside as I moved the head the small amount I could could see both pistons were moving slightly this makes me believe it's not through lack of oil as I always ensure the fuel mix is correct. This it what make me think bearing???
