    175 2 stroke wont rev past 2k

    i've never had one do it but think i've heard they could possibly.. never change one switch box one at a time.. always both.. a bad bias on one can mask a problem with it and/or cause a good one ta goo bad.....

    175 2 stroke wont rev past 2k

    correct on tha stator.. it can even check good with jus a resistance number but actually be "not good"... a bad high side most times a motor will perform normal in all aspects till ya get ta 2500/3000 rpm.. it will still be smooth but jus won't accelerate... timin' after ya chunk tha module...

    Mariner 1996 Outboard 150 [L] bogs down at 2k rpm

    it could but would be down on raw power.. weight and configuration (set up) would determine how it runs with low comp.. jus tired will be different from a damaged hole...

    175 2 stroke wont rev past 2k

    chunk tha "idle speed controller" (what ya call spark advance box) in tha trash... re do timing... after ya throw it away make sure ya have a white/black "jumper" (length is a non issue) between tha bias post on both switch boxes....

    96' Merc 150hp EFI Smokes and surges when throttling up under load

    too much oil doesn't usually effect tha run part.. it jus smokes a little more.. we ran 24 ta 1 in our hot rods with no problems other than a little "smokey" at idle..... black/wet sounds like they are losin' fire for whatever reason....

    Merc 150 efi rev limiter

    A10 was in '96... merc was not real consistent with QC on their ecu's.. should be a "ruff" estimate on tha serial tag on tha clamp.. lotsa factors come inta play with max rpm so take it with tha typical grain a salt.............

    Sport Jet 175 x2 with low compression

    ............. that motor has "electrionic" electrical junk.. it has a single box that replaces switch boxes and it also has an electronic ecu.. these can be a PIA ta diagnose ('specially ona computer)... you need to go by what your manual (if its tha right one?) tells you ta do for carb...

    Mercury kill switch wires
