Outboard motor

Been looking for a 90 HP 4 stroke Yamaha Outboard for my duck boat but having crazy hard time finding a used one. Does anyone have any leads as to where to look for an outboard used?

Not to take advantage of others' misfortunes, but start watching craigslist and dealerships around Llano/Marble Falls. All that flooding might have damaged some hulls and left some motors to be sold.
