Have a 03 Yami F225 about 700 hours .
Few weeks ago was in 5 mph zone motor started to run rough spit sputter stalled . Tried to start would crank for bit then run for few seconds then stall ( seems like fuel issue to me ). Got sea-towed in .
Cleaned VST , replaced all filters , checked for water in gas , tried another ECU , checked every fuse and wire connector, N safety switch .
Fuel rails have fuel and pressure . Pulled fuel feed hose to rails and ran HP pump with YDS fuel is coming out of VST tank .
Did every static test with YDS software all checked out .
Been waiting two weeks for Yamaha service tech to come out ...
I have had this motor for over ten years know it very well I am a tried auto mechanic and think I am pretty good but I am baffled by this one .
