I was just wondering what is going to be the most beneficial manual for me to buy as one of these is $40 and the other is $50 http://www.iboats.com/Evinrude_65_hp_Outboard_Manuals_1973/dm/*******.544672911--list_time.1225228708--**********.550680754--view_id.439637. I am thinking the sevice manual is the one I need as there is no telling what I might have to do to the motor in the future maintainence-wise. Any comments? Thanks.
