    2000 Yamaha 9.9 2 stroke won't start

    Searider, did you even read what the OP wrote? The top bearing sounds likes its shot, the center bearing between the two pistons sounds fine, also how do you expect the two crankcases to seal off from each other if there is no seal between them like you posted. how do you expect anyone to...

    Winterizing New Suzuki DF25A

    if laying it away in storage for long period of time it would be a good thing to know for sure no water was in the gear lube, and making sure the shiny metal inside the motor is well protected along with stabilized non ethanol fuel in the motor and tank

    2012 Suzuki 150 stalls at idle

    if it takes a lot of pumping the primer bulb to fill the VST back up , it sounds like you have a problem keeping the VST full. but the motor should idle after you pump the VST full by hand

    if it s an overheat, you need to fix the alarm system. if the alarm system is functioning properly then I would not think you need to chase the over heat. test the system to see

    2000 Yamaha 9.9 2 stroke won't start

    I agree with the crank not being discolored, looks like a normal crank and rod color. and the OP said the middle bearing sounds just fine, not sure why you call it "shot the middle tough ball bearing"

    Sputtering

    do you have gauges that will show warning lights and a working alarm system you can see and hear if the motor overheats or is low on oil? what RPM is the problem showing you at? I would guess at this point the motor will not go above 2000 RPM when it overheats after a few minutes of running

    2000 Yamaha 9.9 2 stroke won't start

    find out where they send cranks to be rebuilt, and then talk to them about what the cost of reworking a crank would cost. if you ask what the marine tech would charge to rebuild the motor for you, I am sure you would not want to pay that

    2000 Yamaha 9.9 2 stroke won't start

    Being this motor is a 2 cylinder, it would be strange to have both the top and bottom crank seals to go at the same time, but it might happen. there is also a seal between the 2 cylinder crankcases. not knowing what all has happened or done to a motor makes it hard to figure out some problems...

    86 yamaha 50ELJ slipping??

    I also say it is a spun hub. if you want to prove that, mark the hub and prop run the motor to cause the problem and then inspect the marks to see if that are not aligned anymore

    2020 Yamaha 90 buzzing

    I would have tried to charge and test the old battery. but measuring the battery voltage before and while trying to start it may help point to a problem also measuring the voltages at the starter and starter relay may point to a problem with a cable, connection, or battery switch if you have one
