Full StarFull StarFull StarFull StarFull StarGreat 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....

Full StarFull StarEmpty StarEmpty StarEmpty StarNew wires for my tower of power. (Mercury 115 1987 )
by Frederick from Black Mountain, North Carolina on April 05, 2015
The quality of the wires seemed good but I was only able to use two of them. They all seem to be a little short but two of them were to short. I paid $90.00 For 6 wires but was only able to use 4 of them. It dose not seem Fair. Thanks for the chance to post my view's.
