Can anyone give me any hints on troubleshooting my 1972 Mercury 7.5 HP Outboard.
This little gem runs fine at low speed but struggles with high speed.
I have changed spark plugs, coil wires, fuel pump, and cleaned carb.
I suspect ignition coil problems since I believe there is a low speed and high speed section in each coil.
Any suggestions.
Thanks,
