    2005 F90 Yamaha no start

    check rail pressure to see if it is in spec and see if each plug is getting spark at correct time. timing light will help with that Motor needs good compression, good spark at correct time, and the proper fuel to air ratio to start and run

    Inboard fuel tank clogged filters and pickup tube

    How was the tank drained and cleaned? that is the big question. Since you say it was cleaned and all fresh gas put in and it still is plugging things up, whatever draining, and cleaning was done was not very effective

    Adding a water pressure gauge to 1987 70ETLH

    find a spot on the head or tap into the tell tail maybe If my TT stops flowing ,I find out why right away. A piece of weed wacker line stays in the boat so I can shove it up the TT hole to clear debris

    Adding a water pressure gauge to 1987 70ETLH

    most people will not even look at the gauges until an alarm sounds, So not much help. heck the tell tail stream will tell you if the pump is pumping water if you look at it

    monitor the voltage to the High pressure pump in VST. if you have that, then see if the ECU is providing the neg for the pump to run. If the pump runs then you have a plugged up filter inside the VST or maybe a recirculation check valve has a problem

    Yamaha lf200 four strokes not planing out

    hook up a pressure gauge to the rail and see what it reads and if it holds when raising RPM. worry about what to do after you prove that is a problem, if it is a problem I finally tried reading you sideways pic, and it says your rail pressure is not in spec. I would guess your high-pressure...
