The Same Carbs?

Jun 1, 2005
Hello, I have a 1993' Nissan NS3.5A ser.# 309-1-82266 outboard that needs a carb assembly, well I found a used carb Nissan NS3.5A ser.#309-1-68038 online, my question is this the same carb used on both motors. I talked to the person selling the carb and he has no idea what year his motor is but its dark blue where my motor is dark grey. Any help would be great.
Thanks for looking.
