200hp Mercury outboard

over all very complete tidy unit. New power head about 20hrs ago, cost $10,000.00. Bottom end and stering had been rebuilt just prior to me buying the boat. This moter has been propelling the 8m fibreglass boat well as showen in photo's it will travel at 60mph but ecco speed is about 45mph. Reason for selling, this boat was designed and built for inboard and or sterndrive. I want to fit a Diesel / stern drive that will suit low speed pulling lure's over large areas. Prop stainless Quicksilver, 17 or 19inch.
