    slight gas in oil 2009 yamaha 4 stroke

    only way to know if you have the motor propped right is to run it WOT to see what RPM it gets too. you do not have to keep running it hard tho

    15HP Yamaha overtemp light

    service manual for your motor will have the specs. I would think most motors would be the same, but I cannot say that is true

    15HP Yamaha overtemp light

    all I can think of is to do a chemical clean of the motor, good chance there is a buildup in the cooling passages. WOT burns more fuel and creates more heat. and it is not a good idea to keep running a motor that is overheated . the motor lets you know there is a problem, so you need to shut...

    slight gas in oil 2009 yamaha 4 stroke

    make sure the stats operate in spec., cold motor makes oil sometimes slow running, idling, or trolling tends to make oil too over propped does to I think. what RPM will it hit at WOT

    spark to the spark plugs going to them before top dead center, instead of after top dead center while at idle. a timing light hooked to #1 spark plug will show what it is doing

    if you cannot get it out , you can always try putting it back together and hope it seals up OK. might use a little gasket sealer also

    Suzuki DT85 Head Scratcher

    maybe you need to add a foil to you lower unit or transom wedges to eliminate the porpising. my used 16' aluminum Express came with a tail on the Yamaha C40TLRX motor. I removed it and had to get my brother to sit on the front of the boat to stop the porpising. I put the tail back on

    2005 Yamaha 4 stroke low idle when warm

    it probably would help if we knew what motor you are talking about but the idle air control valve would be something to check on

    Gears grinding after re- install drive

    Not that it will help you, but I did find my brothers C60 had a twisted shift shaft and a bent thru pin in the output shaft some years ago apparently from someone trying to shift it while the motor/shafts were not turning to help the dogs line up if the shifter and motor are in the neutral...

    Yamaha 90HP 1999 2 stroke not putting out water

    time to take it apart to see what is wrong and needs to be fixed before throwing it away, maybe just a head gasket or head, or plate in exhaust

    Yamaha 90HP 1999 2 stroke not putting out water

    blown head gasket, or corrosion hole in head or exhaust plate would be my guess

    Yamaha 90HP 1999 2 stroke not putting out water

    that did not answer my question, does the motor overheat if it is kept running for some length of time? but smoke should not be coming out of the place water should be coming out of. is that smoke coming out right after startup of the motor? or is it steam you are seeing after the motor has...

    Yamaha F150 only starts in neutral with throttle or by squeezing fuel bulb

    do those motors have fuel coolers ? sounds like you VST is boiling off the fuel in there causing a too rich condition in the intake, so you have to add more air for it to burn. and pumping the bulb fills the VST so that pump can pressure up the rail

    Suzuki DT5 Shear Pin

    take the sheared pin to the machine shop, they can test to see what it is made of, and make a few for you. I know trolling motor pins are SS or order them from e bay since you say you can find them on there
