    2008 DF90 won't start.

    I was just getting at low voltage to injectors only during cranking, and I would make sure the voltage into the system was good while cranking to eleminate that kind of problem. I have no idea, but a bad connection of either positive or negative can cause low voltage while under heavy load to...

    2008 DF90 won't start.

    Since I know nothing about this motor, I have to ask where was the places you checked the voltages? right at the ECU? were the wires hooked up to those terminals when you did the tests? Did you test without them hooked up? can you test the voltage to the ECU or relays during cranking to see if...

    2008 DF90 won't start.

    If you have good voltage with just the switch on and not during cranking, I would think the cranking is pulling down the voltage or you have a ground problem. have you checked other places to see what voltage is showing while cranking?

    Yamaha F60TLRB 2003 4 stoke - running wonky

    I would try some Yamaha Ringfree Plus fuel additive in a cleaning dose. 2 oz to a gallon of gas. drain all the lines, filters, & carb float bowls. and then pump the new mix into them open the drains on carb bowl and flush some thru, catching what you can and see if any water comes out. crank...

    Difference between 1986 50hp and 60 hp 2 stroke carburetor?

    thinking 40 and 50 were basically the same on older Yamahas, newer ones the 50 and 60 look at the part breakdowns to see what all is different

    Yamaha F100 TLRY - 2 lower units but only one shaft fits?

    if that is true, why is it only the new shaft has the problem? I am not sure how many times he has tried putting the old back up there, but he said it goes with no problem

    2011 Yamaha outboard 40HP shuts down after 30 minutes

    I guess this is a F40 with fuel injection. low fuel level in VST causing the pump to try pumping air instead of fuel would shut the motor down like you turned off the switch. lift pump sucking air, tank vent plugged causing a vacuum to form in tank, restricted pick-up tube in tank, return line...

    Yamaha 200ETXN Surging Idle

    if it is a CDI on that motor, you need to test the inputs that tell the CDI to fire those plugs. if the inputs are not in spec find out why if the inputs are good but the out put is bad, then maybe the CDI is bad
