Great Product
by Michael from Yutan, Nebraska on April 25, 2013
My 1992 Mercury 150 XR6 was being very stubborn in starting and would often flood real easy. I replaced the spark plugs like always (every year) but this time not much help. So I ordered the new plug wires (never replaced them before and i bought the engine new in 1992 - 2013 now). I was satisfied with the price and the shipping cost. Low and behold my engine started write up and I am once again a happy boater. My order was filled, shipped and received in a very nominal time which was also nice. I have used iboats.com before and plan to continue to in the future. Time to go fishing,,,, tight lines....
