    2007 Yamaha F50TLR - Lower Unit Stuck

    16 is an o ring that goes on 14. 54 is the only c clip I see. what makes you think the shift rod/linkage is what is keeping the lower unit from dropping as it should? you telling the OP that he needs to undue the Shift shaft nut has taken this thread way off course

    2007 Yamaha F50TLR - Lower Unit Stuck

    2007 Yamaha F50TLR - Lower Unit Stuck

    simple to look at and see a male and female splined system at that joint. if that connection is rusted together, it might keep the lower unit from dropping, just like the drive shaft rusting into the crank

    1998 Yamaha 50 4 stroke not starting

    are you sure the 4 strokes have that compression ?

    2010 T60TLR Will Not Start

    Telltale stream and exhaust water flow amounts on Yamaha 2000 200hp Saltwater series 2 stroke

    My little C40TLRX does not have any water coming out of the idle relief ports. I too worried about it, but I have not had any problems with overheat since I bought this thing back in 2008. did you replace the whole water pump? housing, cup, plate, etc and all or just the impeller?

    No water stream when flushing Suzuki DF250

    I do not know what all that motors TT runs thru before exiting the TT, but look to see if it runs thru a fuel cooler or something else that may have stopped up , pinched line ,or come off( but that would cause water to be flowing all over inside the cowling) running a piece of weed wacker line...

    1995 Yamaha 130 oil injection lroblem

    some motors limited auto operation if motor is tilted or if it thinks motor is tilted. does your trim indicator/gauge work properly? Does the remote tank level work properly? If it thinks it is low it will not pump automatically.

    2003 Yamaha Outboard oil injection adjustment

    a service manual for your motor should have a procedure to check calibration, but You can always look to make sure the linkage is still hooked up to the throttle. if it comes loose on a lot, if not all motors is should go full on to help protect the motor

    2007 Yamaha F50TLR - Lower Unit Stuck

    Yamaha 4 HP, cranks, runs, but fails to come back from idling down to shift gears

    this would be my thought also. cowling fills up with exhaust gases so not enough o2 for the fuel to burn properly
