    Re: Mercury 1150 weak spark

    Replace that coil, and don't drop the new one!

  2. Re: 1988 Mercury Full throttle then bogs down

    Fuel pump weak? Did you try pumping the bulb when this happened?

  3. Re: Oil pressure reading high after replacing sensor

    The sensors are different for singe and dual helm arrangements. Perhaps you have the wrong ones?

    Sounds like a leaking solenoid valve.

  7. Re: 1968 Merc 110 9.8hp - Sputters or stuck at mid rpm with passengers/load

    That's not a 1968 motor--it had a magneto. Can't see switch box in the photos, which would make it a Phase Maker. If so, the points need cleaning and/ or the plastic blocks on the points need...

    Re: Merc 20 hp switch box testing

    IF that's a Phase Maker, the kill witch works assbackwards--you open the circuit to shut her down (so it must be there and grounded for it to work).

    Phase Maker setups have two coils in the back...

    Re: Timing Question

    This is NOT an auto engine! Ignore the idle spark timing and set it at WOT.

    On the stalling issue, add a 1/4 to a 1/2 turn OUT (after finding best idle) on the idle mixture screws (since these...

    Re: Leaking Carb 1989 Mercury 60hp

    Yup. A dog to work on.

    Jeff

    PS: After rebuilding that carb, but before reinstalling it, clamp it in a vise, hook the tank to it, and pump up the fuel pressure hard as you can. If it still...

    Re: 1967 Merc 500 gear case water intrusion

    ..."i still feel like the gear oil comes out too light colored."

    You may be tricking yourself, for gear oil that's aerated always looks like that. If you leave the LU untouched for a day or so,...

    Re: 2007 90 hp stator and regulator test

    The two (usually) yellow wires from the stator should make around 17 volts AC to ground.

    Re: Tachometer

    Re: 1984 Mercury 50hp jet screw

    If so, you would know it by now! (Ka-pow.) Most likely it's raising the water level where you boat.

    PM me, along with a photo of your carb, and I'll send you one for postage.

  19. Re: Trouble shooting 1979 4.5 Mercury cooling

    I'll bet it does NOT overheating, right?

    Jeff

    PS Those are great...
