    how to break in a rebuilt 60 hp Merc 2 stroke ?

    You mix 2 stroke oil with the fuel in the fuel tank to 50/1. The motor's autoblend system will add in more oil which will make the actual oil ratio vary between 35/1 and 25/1

    CONSTANT SCREACH

    Hook your ohm meter across the oil level sensors wires. Does the reading change when you insert the sensor into the tank?

    2003 115HP Mercury 2 stroke engine - cylinder cuts out when cold at full throttle

    BTW, this is my 2+2 Merc. I think it's pretty smooth.

    2003 115HP Mercury 2 stroke engine - cylinder cuts out when cold at full throttle

    It could be all carbs not getting enough fuel causing the cutting out. It could be right on the edge which might make it more temperature sensitive like cold starting requires a richer mixture. The accelerator pump is only in play when increasing the throttle. Is meant to add additional fuel...

    2003 115HP Mercury 2 stroke engine - cylinder cuts out when cold at full throttle

    I'm leaning toward a fuel pump issue. If you haven't rebuilt the fuel pump yet, you might as well try it. Otherwise you can try this test. Take it back out to the water and have somebody ready to pump the primer bulb. Try to duplicate the issue. If pumping the primer bulb helps then it's...

    1987 Evinrude 110 success

    I tried your 1/4 inch gap on the throttle cam mod on my merc. It seemed that cold starting had improved. I barely touched the key and it fired up. Acted more like a warm start. It also seems like throttle response through the lower rpm range may be smoother. I'll continue testing to be sure.

    Possibly a Bad Stator

    Something is grounding the black/yellow wire. Might be key switch.

    J150EXECD Looks like I need a new float?

    Why not put the old float into a small container of fuel. Weight it down with something overnight so it's under the fuel. Then release it the next morning. Does it float back to the top? If so it's good.

    Intermittent Starting

    Could be switch, wiring, connections, solenoid or starter. Check all connections and use a voltmeter to check for 12v from starter then all the way back.

    Possibly a Bad Stator

    Did you disconnect the stator wires from the switch boxes before measuring them? Dead short to ground does not sound right. The information I have (for my motor. Yours might be different) states to read the resistance between blue and blue/white wires. Should be between 6k and 7k ohms. Then...

    Possibly a Bad Stator

    Are you reading the stator wires or the trigger? Stator ignition wires are usually red and blue.

    2002 Mercury 150HP Alternator

    It's under the flywheel which is under that plastic top cover. Those voltages sound about right. Are you sure your battery is good? Did you check the battery connections?

    98 Evinrude 115 carb adjustment?

    Yep. Check your battery connections and also the state of your battery. Also make sure the spiral shaft of the starter the bendix rises on is clean and lubed.

    Quit on the Water!

    I believe the wick is normally held in by a small bracket under one of the coils. https://maxrules.com/graphics/tuneups/coilinstall.jpg I trimmed down the wick when I did mine.

    50 4 stroke runs out of gas

    That low pressure fuel pump, is it electric?

    50 4 stroke runs out of gas

    Just a guess because I don't have any experience with that motor. Low pressure fuel pump not working?

    1980s mercury 115 tower of power issues!

    My mistake. It's just that TCW-3 is normally grayish blue.

    1980s mercury 115 tower of power issues!

    The fuel in the fuel filter does not look good. Does not even look like it has any TCW-3 in it.

    Quit on the Water!

    The rubbing arm is longer because they're worn down on the old ones. Yeah, .020 gets you in the ball park. There is a youtube that shows how to set the points to the gnats ass using an ohm meter and marks on the flywheel.
