I have a pair of 2007 marine power 8.1 liter gm engines for sale. Both engines have 100 hours on them since rebuild in fall of 2017. Each engine is 496 cubic inches with 450 hp a piece. They are currently in a twin engine jet boat that can be surveyed and started. They will be removed and put on pallets once the auction is paid for. They motors have been maintained on a daily basis and never run hard. Were never pushed past 3200 rpm. The only reason we are removing and selling is for a diesel conversion.
