    Timing and synchronizing a 1988 v4 130 hp 2 stroke. Need help.

    are you sure the spark is not going away when you set to normal or close to normal timing? just thinking wiring moved a certain way ends up killing spark maybe. there is a key, I guess it could be sheared But, TDC on pistions and marks on flywheel line up it should be good.

    Timing and synchronizing a 1988 v4 130 hp 2 stroke. Need help.

    I did not read anything about using the choke while trying to start. but raising the fast idle lever not only opens the throttle to allow more air in, it also may change the timing some also like you wrote. Could there be too much fuel to air for the cylinders to fire? do the plugs have spark...

    09 HPDI 225 3K RPM's in Forward

    switch, adjustment, or wiring maybe the softwear will be able to tell what is or is not happening. need to know the rail pressure is in spec also. takes more fuel to make it go when loaded up in forward in the water, but that should not drop cylinders unless injectors are not doing what they...

    well if it has a new buzzer in it, you need to find out if it gets 12V+ to it with key on, and if the other end of the buzzer has a good ground to make noise

    NO GO!!!!???

    Good to hear it is running better, but I do not understand how the float setting would keep it from running at higher RPM. were they way off and not letting fuel into the carbs?

    NO GO!!!!???

    some Yamahas do have a low speed and a high speed charge coil. I have no idea if yours has that or not. your service manual for that motor would have info on that

    F4 water issue

    if you replace the pump housing, cup, impeller and wear plate along with the gaskets and orings, and make sure the pipe sits in the bushings at pump and in powerhead, that is all you can do. unless the pipe has a hole in it. if you have air or steam coming out the TT, I would think head gasket...

    Yamaha 2008 90TLR oil injection

    well I was totally wrong on this motor. what can I say, but sorry. but I would think that the oil tank should have a drain on it coming from the very bottom. water is heavier so that should come out 1st. as it drains the alarm should sound. once completely drained you pull the float assembly...

    Yamaha 2008 90TLR oil injection

    drain the oil into a clean glass jar so you can see any condensate/moisture. if it is good oil you can put it back in after turning on the key and timing how long it takes for the pump to fill the tank back up. the alarm should sound when low and stop alarming when filled back up
