    1999 yamaha 2 stroke 9.9 to 15hp conversion

    Neither could I. I looked at every line item of every page in the two parts manuals. Only difference I saw is the reed valve assembly. Surprised me actually. I was expecting the CDI assembly to be different.

    250 Yamaha SHO Speed

    I tried to find your model at Yams website. Could not find your exact boat. From what I can see from looking at the PB's, 40 MPH does not seem unreasonable but it depends upon the atmospheric pressure (motors make more or less HP depending upon the weather) and the weight of the boat...

    yamaha 6y5t gauge hook up

    Sounds like you might have a 703 side mount control box. You did not say what you have. If you simply follow what the diagram shows you will have no problem. Four single colour coded wires (one of which is not used) with bullet connectors and one four pin connector. Pretty difficult but some...

    If you cannot understand that diagram then the motor needs to be taken to a mechanic that knows Yamaha outboard motors.

    Yamaha 70B too much Autolube

    3.80cm3 for each of the three cylinders? Was the oil pump lever in the full throttle position? Seems excessive. Have you thought about doing a 9 minute test for more accurate results? Were you using Yamalube?

    Yamaha 200HP Ignition Switch Replacement

    Post a photo of your control box please. Might not matter however. The key switch for a the panel is what matters. Remove your key switch and see if the configuration is the same as the latest key switch.

    General MAP sensor question

    It might. ECU thinks there is a lot of air in the intake manifold. Adds too much fuel trying to get the fuel/air ratio correct.

    Yamaha 200HP Ignition Switch Replacement

    Well now I am confused. The 703 control box has an integrated key switch. And kill switch. Your photo shows a standalone key switch panel.

    yamaha 6y5t gauge hook up

    No. There are two kinds of tachometers. Analog and digital. Analog uses the ivory coloured four pin connector with four wires. Digital uses the while coloured two pin connector with two wires. Either type will work with your motor. Just depends upon what you want to do. You mentioned the 6Y5...

    The bright white connector with a cap on it, with but two wires, is not used with a 6Y5 tachometer.
