    97 Mariner bogs

    97 Mariner EFI 200 Mag. Has compression from115 to 111 starts good runs and sounds good in the water up to 1700 or 1800 rpm, when the sound changes like its trying to open up it bogs. Have checked fuel system and besides it looking like it brand new inside it all checked out. With fuel pressure gauge installed it runs 38 psi thru the total range that it will run, pressure never dropped off. When it bogs it almost sound like it developed a miss. I brought this to repower. I have never heard it run.

    IT sounds like the high speed stage of the stator is gone. I bet it starts and idles fine, and as soon as you try to open it up..booooooggg

    do resistance test on the stator.
