Had a customer that has been playing with his 2000 175 Ficht for a few weeks now. He did not want to spend the money to have us look at it. He has been playing parts swaper and has purchased appox 700.00 dollars worth of parts from us. He finally broke and dropped it off. Turns out the auto parts store sold him QL77JC4 spark plugs. When he priced our plugs he stated he found them cheaper somewhere else. Threw in the correct set of plugs and away he went. Guess he did not save that much money now.
