My sister is a veteran garage sale junkie and picked up a 74 20 HP Merc for $ 39 that was allegedly running a year ago. I just rebuilt a 75 50 HP so unless it is reallly dogged man she scored a heckuva deal. Any known issues you guru's know about on this engine. Serial number is 4053627. Can't wait to tear into it and get er on the H2O
