i work on a 34 venture twin f225txrc, port motor runs fine , starboard motor will not turn up past 3800,when pushed all the way it falls way off, misses ect.changed all filters, ran off seperate fuel source(12 gallon tank) runs better but still not good,ran new control cables, over the weekend, could i have pinched the fuel line putting back in the rubber rigging hose grommet, or could it be low pressur fuel pump, also changed the thermostats, i did remove what i think is the throttle posistion sensor, to change thermoststs,i am trying to describe everything done to diagnose the problem, thanks for any help
