    yamaha 2000 25hp f25eshy no fire

    your definition of fire must be different than mine. without all 3 of those things I mentions the cylinders will not fire and burn properly. maybe you are speaking about no spark to the spark plugs

    yamaha 2000 25hp f25eshy no fire

    motor needs good compression, good spark at the correct time, and the proper fuel to air ratio in the cylinder to it to fire properly. you need to start troubleshooting to see what is good and what is not

    White Smoke😑

    seems you said it died and produced white smoke. "But when I put it into gear or accelerate, it will die and produce lots of white smoke." now you say it produces white smoke at idle and and then dies which is it? And I have a hard time believing you cannot see where the white smoke is...

    White Smoke😑

    blue smoke and running rough would be what I would be chasing not water right now. unless you find signs of water in the cylinder or on the plug itself. white smoke after it dies, I am not sure what that is. steam I would expect while it is running if water was getting into a cylinder

    2000 Yamaha 50HP bad center cylinder

    you did not say if you see any damage to #1 AND #3 we cannot see in pics. are you going to open it up and look at bearings ? that will help tell if lack of oil was even part of the problem. I believe Rodbolt once said lack of oil will get bearings before pistons

    2000 Yamaha 50HP bad center cylinder

    what about running too lean do to carb plugging on only #2 ? that may cause #2 to run too hot and being between the other cylinders it got hotter than the other 2. do you see any damage to the other cylinders we cannot see? but as others said, you need to take it apart to see if bearings and...

    Need to buy a CDI for 1988 Yamaha

    the kill switch and ignition switch grounds the spark voltage to kill or keep the voltage from reaching the spark plugs to keep the motor from running you may want to be sure the switches and/or wire to the CDI is not grounding keeping the voltage from showing up

    White Smoke😑

    and then a leak down test to see if combustion chamber is leaking into the cooling system.(head, head gasket etc) could be in the exhaust, but not likely

    Not going over 2 rpms

    never seen a motor that could run at only 2 rpm. most idle at around 700 to 800 rpm but yes over heat or low oil level will limit rpm on most motors that have that system
