    yamaha 2013 waverunner

    what is the fuel rail pressure doing and compression reading on each cylinder? no need to post videos, just give the readings. waste of your time and ours watching I never heard of someone dumping pure ringfree into a cylinder before, where did you get that from?

    Crud in carb bowl

    I would think it had water or some other stuff in the bowl to look like that. what did you use to sonic clean the carbs? I am having a hard time figuring out what a 2004 Yamaha 40ELPTO is. that does not line up with anything here in the USA

    Stalling low speed outboard

    Without the model of your motor, all I can do is guess this motor has carburetors and you talk about a choke for cold starting. sounds like your carburetors need cleaning. Pilot/ low speeds jets/passage have a problem

    30hp yamaha outboard not firing one 1 cylinder

    measuring the peak voltage into and out of the CDI and comparing those readings to spec in service manuual may tell you if there is a problem with a charge coil, pulser coils, etc. It is very hard to know what tiny fire means

    2008 Yamaha P90TXR block

    I did something similar to the exhaust plate on my C40. But used JB weld marine putty. You need to use a file to make sure the sealing surfaces are flat and in line with the rest of the surface. hard to do with the power head bolted on the motor, not much room.

    2008 Yamaha P90TXR block

    z200txrc wont run

    Key switch would be the 1st thing I would be checking. Something is getting power in start position, but not in run position. But it never hurts to monitor fuel rail pressure, spark, and injector firing to see what is missing to narrow down what to be looking for.

    Finding model # on my Yamaha

    from what I have read and seen it is not a metal stamp, it is a round sticker with a serial number for your motor. you can use that to get the model on Yamahas site

    To low idle speed

    ECUs can be damaged by a stuck IAC also, the ecu keeps trying to adjust the idle and overheats the internal ecu circuit. you can try to get them to help, but I would not expect them to

    2019 suzuki 20hp alarm

    possibly overheated and warped the head. check plugs for signs of water, do a compression check or leakdown test on the cylinders

    Identifying a 75hp 2stroke (i think) 2005 with missing model number (and it won't start )

    I would think it would work just fine, but who am I to say. any 12 volt start relay/ solenoid that can carry high current should work. maybe someone put something in there that was not original, so the numbers do not match up.

    '98 115 Yamaha runs hot if over 4,000 RPM's

    inspect the plugs to see if any cylinder is running different than the others. as said if you did not find any parts of the impellor missing to plug up cooling passages, I would drop the lower unit and run some Rydlyme marine descaler thru the motor for a couple of hours to see if that helps.

    Fresh water corrosion and anode choices…

    you seem to have missed the part about stray current mentiond. that can eat up metal quickly.

    2002 Suzuki df70 overheating

    yes pieces of the impellor can plug up passages, causing over heat. you can try dropping the lower unit and pulling the stat out and hooking a water hose directly to the pipe up to the power head and injecting compressed air into that also as you try flushing things out. but you may have to...

    Yamaha sluggish acceleration

    wild guess is eithr the fuel pump leaking fuel into crankcase or pilot jet/passages . take the carbs apart and pump to see if there is a problem you can see
