With the older outboards, those engines were built when fuel was vastly different, so changing over would have some initial cost to it...rebuild/replacement of parts in the carbs, certain plastic parts, fuel lines, etc. that were used were not designed to handle the various additives in the fuel of today...
Some things would be quick with fuel lines, but carb parts and gaskets might be a bit harder to come by being out of production for so many years...
Once converted and prepped, I would see no issue with the change and the motor would run quite well on it.
