Twin 2002 mercury 250EFIs. One standard one counter rotation with XL shaft length 25. Both engines have been meticulously maintained and are completely OEM. All routine maintenance such as fuel filters, plugs, water pump and gear lube is up to date. Complete cooling system was refurbished and fuel system cleaning including injectors was done 3 years ago. Engine controls and wiring harnesses are included. The engines operate flawlessly and are still on the boat and can be demonstrated. Only reason for sale is I purchased a new set of Mercs.
