well heres the deal.. kinda got screwed ( I THINK)<br />had my mechanic come out and go for a drive on the boat, and he suggested that he was sure it was the antisiphon valve.. so we go back to dock and he pulls up the floor to get the antisiphon off and seems to be ok.. tries running without to see if it corrects the problem.. no go.. so as we float out on the lake pondering what it could be.. the fuel pump?? well , I suggest the carburator fuel filter..( he says no.. usually that wouldnt cause the problem you are having. I say "I have a spare on the boat in my toolbox.. lets try and see (cant hurt.. ) So we change the filter and just as he pulls it out, he says" OH YEAH heres the problem... the paper type filters are junk. So he installs my spare part, and we run the boat.. What do you know.. PROBLEM SOLVED>>> no sht. Now i bet he feels dumb. So we pull back in the marina and he tidys up his toos and so on.. goes to W Marine to get a replacement antisiphon valve (cuz he broke the original, Comes back and installs it.. and then says , you know i am going to have to charge you something.. (total time on my boat=1 hour.. ) He claims 1.5 hrs of labor $75 and $20 parts... (WHAT??) I diagnosed the problem and had the part on hand. He replaced the antisiphon cause he broke it... And on top of it He gouged me on the part..said it was $20- (I went to west marine after and saw that it was only $13. And west marine is about two minutes from my marina. What a dic... i feel i got ripped off. OH well (LIVE AND LEARN) what are your thoughts... THANKS
