by Tim from Winston Salem, North Carolina on May 20, 2016
I received my spark plug wiring kit, however there are no instructions and did not include the correct tip clips to put on the spark plugs , now I have to return them or spend more money and time and order new boots with correct tip clips included....Very frustrating! Save yourself time and order the spark plug wires already assembled for your model engine. What a PIA this turned out to be!

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....
