Can anyone give me some advisement here? I am looking to buy extra electrical components for my 1986 Force 125hp motor. I found someone who is parting out a 1990 Force 120hp motor. My questions are- Are the CDI boxes, coils, and starter motor compatible to my engine, and if so, is $200 a good price for these items or is that a ripoff for used parts? I am new to boating so I just want to make sure I am not getting taken for a ride here.
