i have a 97 trophy model 2002 it has a 97 force 120hp on it. i picked up a 98 mercury 225hp offshore efi to put on it. im i need of some help with the wiring i didnt get the plug for the 225 but the one from the 120 looks the same so can i just plug in and every thing will work or do i have to re wire? if someone has diagrams for the moters or can point me in the direction to find one that would be great. or if someone could explain to me what all the wires in the harness control. its the round 8 pin plug. one more thing the 225 is oil injected is there a way i can un hook the oiler for temporary i have about 70 gallons of mixed gas in the tank and dont want to drain it.
