Model/Year compatibility

[riverracerxxx]

What is the compatibility (controls, wire harness etc.) between different years and HP of Mercury outboards? Have a '08 60hp Bigfoot 4 stroke. Would like to upgrade to a higher HP (90-115) 2 stroke, and probably a few years older than what I have. Would like to leave all the controls in place and just swap out the motor.

Thanks

There is an adapter harness Merc sells, 8 pin to 13 or 13 to 8.

[riverracerxxx]

does that mean that the harness and controls on the boat could work with any Merc outboard?

Anyone have any info/knowledge on this?
