looking at a boat (78 tahiti w/merc 140) will run all day at 3/4 but you hit full throttle and it dies.. Owner says when he got it, it had old gas in it. He emptyed the gas , put in fresh has ran it about 6 times but still wants to die at full throttle...<br /><br />To me sound like just a fuel issue, maybe run a tank or two through empty the float bowl on the carb , maybe run some kinda cleaner through ??? <br /><br />WIll this be easy to fix for 2500 it's a great deal
