    Water in lower? Yamaha 4

    that 1st pic looks like a lot of water flowing out around the lower unit. I am not familiar with those small outboards, are you sure you have the tube shoved down into the water pump seal properly? maybe it moved as you put the lower unit on

    Prop caught on trap, engine wont turn over

    does the starter engage but not turn the motor? or is the starter not even tying to energize? some 4 stroke motors have the oil pump run off of the drive shaft, so if that is not in place then there is no oil being pumped It is always a good idea to state the complete model # of the motor you...

    Yamaha 4hp 2 Stroke Powerhead Removal

    follow the path of the TT to see where it goes into the powerhead, and disconnect the hose from there, to clean it out better in both directions. I am guessing there is a hose making the connection between the two.

    High Altitude Rejetting

    Carburetor question on restoration I’m working on 1992 40 hp MSHQ Yamaha

    the only time a 3 cylinder motor will not be sparking on all 3 cylinders at the same rate is if there something is wrong with the ignition system components. spark is driven my the flywheel turning rate and it does not change speed for the different cylinders adjusting the individual carb idle...

    2000 Yamaha F50 high rpm in idle.

    I would think if it has a choke and the linkage hangs up there could be a problem. as I said look to see if something is hanging up keeping everything from going to the idle position.
