    2002 Mercury 150 EFI overheating drama.

    "There were 3 small stones and a tiny piece of stick in the poppet table cavity after the valve seat." this would give reason to pull divider plate check, clean.. pull powerhead to check, clean adapter plates.. heads could possibly be involved also. water pump "kit"? or jus tha impeller?

    trash tha "idle" speed box.. it has white/black, white/red wires going to tha switch boxes.. you may have to make a short white/black jumper that goes between tha bias post of both switch boxes.. reset "max timing" at 23*... if that doesn't help ya probably gonna have a suspect ecu............ jmo.

    justa 'bout everything BUT block half, pistons, rings, center main bearings (different crank) .. as for everything else ya gotta know tha difference, but can be used.. tha 150 is a 2.0 steel sleeve motor and your 175 is a 2.4 chrome (same as 200) bore motor which is tha MAIN difference

    275 mercury 2 stroke

    you might look on CDI website for stator values and replacement??? tha 3.4 is an odd bird motor anyway.. not much info out there about it.. values not in tha OEM manual is strange for Merc!.. i've looked at everything i have access to and came up with "0" other than parts list... good luck...
