Hello,
I have a 2005 Four Winns Horizon 200 with a Mercury 5 Litre MPI engine. The boat wont idle. I can get it running and into gear quickly and it then runs normal, no hesitation issues. When I pull it back down to idle it stalls. Changed the fuel filter, no change. Marina says fuel pump is bad and they have to pull engine to replace fuel pump. I dont understand why it would be a fuel pump when it runs great once you get the rpms up. Any comments would be appreciated.
Thanks
