    2005 Yamaha 70B running rich

    Specifications will be in your Yamaha service manual. Since the voltage to the Primestart come from the lighting coil, it might stand to reason that the specifications for the lighting coil will be one and the same as for the Primestart device.

    Yamaha differences 2013 F115XA vs JA vs LA

    F115XA = 25" drive shaft length. F115LA = 20" drive shaft length. F115JA = Jet drive lower unit. I have no idea what is being referred to with respect to "analog" motor. The motor is mechanical. The ECU processor is digital. Both analog and digital data outputs are available from the ECU for...

    Oil Adjustments for Yamaha 2001 hpdi 150.

    Check the throttle openings to verify they are the same. If not, one motor could be making more power than the other and thus using more oil. Check the oil link rods to see if they are in specification and set the same. Not uncommon for a clip holding the linkage in place to get old and break...

    F250 TXR RAN OUT OF FUEL, NOW CANT GET FUEL TO INJECTORS

    Have someone turn the key on when you have your ear as close to the vapour separator tank as you can. Listen to hear if the pump runs or not. If you hear the pump run but no pressure, that is one thing. If the pump does not run that it a different thing. If you cannot hear the pump run then...

    Problem with controller on F70LA

    Yamaha calls that the ECU. Engine Control Unit. How long did you run the motor with your brothers ECU? I would suspect that you have a wiring or connectivity issue. The odds of two failed -02-00 ECU's is nil...

    Yamaha F80TLR starting challenges

    Sounds to me like the carburetors, particularly those with the Primestart device, need to be thoroughly cleaned. By cleaned I mean the carburetors completely dismantled and soaked in a heated ultrasonic cleaner, using a good cleaning solution. Then all orifices and passageways verified as being...

    Yamaha OX66 2002 150hp - what is considered low fuel pressure?

    Damn my reading skills. Title of the post is Yamaha OX66. But in the first paragraph you mention HPDI. Is your model a VX/SX150 or VZ/Z150? Big difference.

    Yamaha OX66 2002 150hp - what is considered low fuel pressure?

    Many have reported that the $55 alternatives work just fine. Last a long time. It will more than likely outlast the motor.

    Yamaha OX66 2002 150hp - what is considered low fuel pressure?

    It is normal for fuel pressure to vary. Highest pressure will be with the motor not running. Say for instance when the key is just turned on. At idle RPM the fuel pressure will at its lowest. As the throttle is opened and the manifold pressure increases, so too will the fuel pressure. Retard...

    2001 Yamaha 50hp tlrz 2 stroke with prime start system starts and dies

    Wrong manual for your model. In the scheme of things it should not really matter. Neither manual shows the term "emergency" for the Primestart component. Yamaha is terrible about manuals not agreeing or parts and a manual not agreeing. Neither manual shows a label for the "automatic" position...

    Yamaha 15a 2 stroke info help

    Yamaha ships motors all over the world. Under the Yamaha brand, under the Mariner brand, under the Marathon and under the Mercury brand. Perhaps under some other brands. The information about a 662 model that I provided above is from Mercury Marine.

    2001 Yamaha 50hp tlrz 2 stroke with prime start system starts and dies

    Where in your manual are you seeing an "emergency" position? What page please? The manual for your model is LIT-18626-04-48. The manual says to "open" emergency starter valve. That is, turn it to the "open" position.

    Yamaha 15a 2 stroke info help

    Appears to be a 1975 model year motor. Distributed outside of the USA. As noted, Yamaha did not selling motors here in the states until 1984. Mercury sold similar models that were made by Yamaha. What parts that remain available might work on your motor.
