    2 Stroke Yam 8B of Unknown Year.-

    Never heard of an exciter coil on a Yamaha. I am guessing that is the charge coil. Are there no markings on anything to help ID the motor?

    oil transfer pump

    Why did you not ask how the system works? That being known makes it a hellava lot easier to trouble shoot a problem.

    oil transfer pump

    If the motor is a 1996 or later model (you did not give us the complete ID) then the automatic oil transfer system will not work unless the motor is running. Except for one condition. That being when the motor is new. Main oil tank empty. Remote oil tank full. With key on the pump will run for...

    oil transfer pump

    What is the complete model of the motor? Are you talking about using the emergency toggle switch to run the pump motor? If so, why are you using the emergency toggle switch?

    1989 Yamaha 50ELF 2 Stoke CDI Operation - Overheat Circuit ?

    What manual are you looking at? I don't see a yellow/red wire connected to the CDI. I see only a yellow wire. Unconnected wire. When you say you are seeing continuity on a yellow/red wire, continuity with what? The over temperature wire is pink. It connects to the thermoswitch. Motor gets hot...

    Is the block installed? If so, and it is obstructing the removal of the part, then I would think that the block will have to be removed.

    Just Purchased used 175 Yamaha Outboard (Are theses good engines)

    A Yamaha multifunction tachometer is a useful tool to tell you the status of the oil injection system. Low oil in the remote tank or low oil in the main tank. Alarm will sound with low oil in the main tank. Motor will also go into RPM reduction mode.

    Just Purchased used 175 Yamaha Outboard (Are theses good engines)

    1990 model year motor. 30 years old now. One of the best that Yamaha ever produced. The D in 175ETXD denotes D for the model year. 1990. Used again in 2005 but for different models. Leave the oil injection system alone. One of, if not the, best made. The linkage referred to relates to how much...

    Difference between 2014 Yamaha F8 and F9.9

    The best that you can do is to prop the motor so that with the boat loaded and the throttle wide open it will run at or near 6000 RPM. Maybe play with the engine mounting height and the trim angle.

    Difference between 2014 Yamaha F8 and F9.9

    From where are you getting your information? A 2010 F8CMSH is very different from a 2010 F9.9FMSH.

    Difference between 2014 Yamaha F8 and F9.9

    In what country are you located? Reason why I ask is because here in the US the F8CMSH was last offered in 2010/2011. Long time before 2020.

    Difference between 2014 Yamaha F8 and F9.9

    Are you trying to compare an F8SMHA with an F9.9SMHB? Just saying F8 versus F9.9 is no longer enough. These are the two models that were manufactured in 2014. Open the Yamaha parts catalog for the F8SMHA. Open the Yamaha parts catalog for the F9.9SMHB. Then open the same illustration for each...

    Trying to figure out what model/year this is.

    I have not a clue as to where it was distributed. I would suspect that a 1984 25GM model would be very very very similar to a 1984 USA 25SN/25LN/25ESN/25ELN model, as applicable. Presumption being that your model has two cylinders.

    Trying to figure out what model/year this is.

    1984 model year motor. Model 25GM . Just like the label says. Where are you located? This is a US website. The 25GM model was not distributed in the USA by Yamaha US. That is why you will not find it at the Yamaha USA website. If that is where you have been looking for parts.

    If the throttle has to be opened to help start a fuel injected F90 then something is amiss within the motor.

    Yamaha f90 starting issue

    Carefully inspect the main engine harness wires to the IAC connector. The wires have been known to snag on the cowling when the cowling is being removed and getting damaged. Carefully inspect for any signs of damage. Might be hard to see.

    1992 Pro V 115 Oil Bypass - Low power question

    What country are you in? There was no 1992 P115 offered by Yamaha USA here in the US. First model offered in the US was the P115TLRR. 1993 model year motor. By low power I am presuming that you mean the motor is going into the RPM reduction mode. Low oil in the main oil reservoir will cause...
