Hi all, I have dual station icon controls, the upper station throttle tension is shot, I assume whatever the tension mechanism is has deteriated or the tension screw is stripped.  The control part # is 764909 which appears to have been superceded by part # 0767053.  my question is are these just a direct swap out or are dealer tools needed to program the new throttle to the engine.  Engine is a 2020 250HP.

thanks and tight lines!!

The control should just swap out. It is precalibrated.  The newest part number would have the right firmware.
the friction control has more likely disconnected due to over torque of the tension screw.

is the engine under warranty?

Sorry, fat fingered the year, it’s a 2010 so not under warranty. I was going to see if I can first see what the problem is inside the control before dropping 1400 on a new one. It is in the tower so any wave knocks the throttle forward unless I’m holding it. Thanks for the reply.

my next comments are presented as opportunity only and not as any type of field repair or recommendation. Undertake at your own risk as I have zero knowledge of your technical skills.
I have disassembled  / reassembled the control several times. After the control is removed from the dash panel, turn it over and you will see a rubber gasket. Carefully remove the gasket and you will see a series of small recess’s and screw heads. These are torx head screws. 6 to 8 screws or so. These screws hold the gray top cover in place. Carefully release the cover paying attention to an electronic ribbon connecting the top cover to the main circuit board. Gently pull the connector body out of its connection point on the main circuit board. Once the top cover is removed you will have full visual access to the tension screws and any problems.
You must also be aware that the gray top cover includes a gasket seal to prevent water intrusion. Retorque the screws evenly to allow the top cover to seat evenly. There is no opportunity to verify the seal integrity upon reinstallation. DO NOT attempt to reseal with silicone sealers. Acids from the fumes of these sealers may damage the electronics.  I make no other suggestions for an alternative sealer. 

good luck

thanks and I appreciate the info, I've fixed fish finders, VHFs, cell phones, PCs and more so I may give that a try.

Thanks again.

the plastic collar that provides tension to the throttle is cracked at the bottom where the tension screw threads in, I'll deal with it for this season and see about getting a new throttle later.  thanks again for the help.

Why not try and glue it up?

wasn't quite clear how to get the actual throttle assemly out of the housing in order to get the plastic collar off.  There's enough friction to hold it in place while going slow which is most of what I do in the tower looking for cobia, however once on plane it's a chore to keep her rpms steady.  When fall comes and I don't need the tower as much I'll give it another shot, maybe send pic and get some help on the best way to remove the throttle cam from the housing.
