    Yamaha F225 ECU Upgrade

    The ECU is monitoring engine temperature. If and when the motor gets too hot the ECU will sound the alarm and put the motor into RPM reduction mode. The Command Link gauge will indicate the problem. Is it all that important that the NMEA 2000 display indicate some particular temperature value?

    Yamaha F225 ECU Upgrade

    An F25TXRD model came with a -30 ECU and a -50 wire harness assembly. The first F225 with full Command Link capability was an F225TXR model with a production date of April 2005. It used a -31 ECU and a -51 wire harness assembly. The -30 ECU was replaced by the -31 which was replaced by the...

    Yamaha F225 ECU Upgrade

    What is the engine ID of your dad's motor? Along with the ECU changes there have been some wiring harness changes. Need to make sure that the wire harness on the motor is compatible with a later dash number ECU.

    Yamaha F225 ECU Upgrade

    Command Link is Yamaha's terminology for NMEA 2000. If temperature sensor data is being seen on a Yamaha Command Link gauge, and other engine information is being seen on the Command Link gauge and on an NMEA 2000 display, I am not understanding why that data is not being seen on the NMEA 2000...

    Anyone knows the ring gap size

    I had given the guy a link to where he could buy his manual in an earlier thread. $15 bucks for a pdf viewable copy. In response to a request of his. I can only guess now that he wanted a free manual. Obviously he did not buy the manual and came back here for free information. I don't suffer...

    Better to beg on the internet than to pony up some money for a manual.

    Numbers on OX 66 CDI

    You are welcome. I should have noted the dash numbers are not related to the calendar years. All part numbers start out as -00-XX. If and only if they are updated do they change to -01-XX and so on and so forth. The last two characters/digits in the dash number is a color code/finish code, if...

    Numbers on OX 66 CDI

    The Y in the model identity SX250TXRY indicates it is a 2000 model year motor. The parts catalog shows that the SX250TXRY was delivered with a 65L-85540-01-00 CDI. The -00-00 and the -01-00 CDI's have been superceded by the -02-00 CDI. Either the 00-00, the 01-00 or the -02-00 CDI's will work...

    time to replace power trim relays on merc 90hp 2001 again?

    Easy enough to trouble shoot the relays. Swap the up and down relays. See if the problem moves from the failed side to the good side and vice versa.

    time to replace power trim relays on merc 90hp 2001 again?

    See if you can find some solid state relays that have the current carrying capacity of the mechanical relays. Generally they have a much longer service life. I suspect once you see the price of the solid state gizmo it might make sense to carry a spare mechanical relay.
