Re: 70 HP Mariner Wiring Schematic
Welcome to i-boats Ed. Your motor looks to be a 1979 year. Best bet for the schematic is to buy a manual for your motor. Factory shop manuals are best but many people use either Clymers or Solec. Read some negative discussions about the Solec manuals recently on these forums. You might also want to try the local library for service manuals.
