    cant find out the year of 90hp yamaha

    For Yamaha motors distributed by Yamaha USA, the letter in the lower right hand corner is irrelevant. The letter P means nothing to a user. The fourth letter in the USA model code denotes the model year. For example, using the F225TXRC above, the letter C means that it is a 2004 model year...

    2006 225 4stroke runs poor until warmed up.

    How can you be trouble shooting and working on a motor without having the applicable service manual on hand? Appears to me you are doing maintenance for compensation. Why are you depending upon the largesse of the Iboats community to help you in a commercial situation?

    2006 225 4stroke runs poor until warmed up.

    Thermostats are used to help the block to warm up faster and to ensure that the block can come up to operating temperature in cold water. They are purely mechanical and are not connected in any way with the thermoswitches or the thermosensor. The thermoswitches close if either is over heated...

    The only markings that count at this point in time are whatever is found on the CDI assembly and the carburetors.

    Where are you seeing the y-3 688h 04? The y if not on the PID label on the does not mean the year 2000.

    The motor would have left Yamaha with a round decal on the block. Usually in the vicinity of the starter motor. Has some numbers on it. What are they? Look at the CDI assembly. What numbers/letters are on it?

    break in

    Making oil is not a warrantable defect.

    break in

    Take a look at the Yamaha break in procedure. Then take a look at the Mercury Marine break in procedure. Then you might have some idea as to why Yamaha's suffer from making oil at a higher rate than do Mercury's.

    break in

    On some Yams it is critical. Otherwise be prepared to deal with the "making oil" phenomenon. Too bad the model of the motor is not known.

    2001 t9.9 4 stroke

    Yamaha calls it Primestart. An automatic fuel enrichment system. Adds extra gasoline when the motor is cold. Not uncommon for a 21 year old motor to be seriously in need of a thorough cleaning.

    Ex RNLI Yamaha 75 CETO question

    It is a stretch, but what with some carburetors having miniscule orifices and passageways perhaps the slightly higher viscosity gas/oil mix might be hindering the flow of fuel to the motor.

    Ex RNLI Yamaha 75 CETO question

    If 75/1 works better than 50/1 one could presume that the Yamaha recommended 100/1 gas/oil ratio might be better. Cost little to nothing to give it a go.
