I bought this Nitro from a very well to do person who took tender loving care of this boat and used it very little. The Mercury Optimax 90 was added new in 2008 and has just 20 hours of use. This engine automatically mixes the gas and oil. The boat has a beautiful blue metallic finish. Everything works except one of the fish locators. Options are bilge and live well pumps, trim, radio, reverse gear, stainless steel prop, and trolling motor with foot control. I keep both batteries fully charged. I had this boat for two years and have had it out twice, its an awesome experience for someone who will have the time to enjoy.
