Push Start AR 240

[FloJet]

So here's a thought. What you all think? Yamaha parts store sells the panel switch assembly and the switch assembly for the push start system on the limited SE. If I was to get that, I wonder if I could replace that component with my key switch assembly on my AR240. I don't understand how I wouldn't be able to. But hard to say until I get a closer look at how the push starts are assembled from factory. I am betting this should work just fine as it's going to be some kind of start relay in the back. Maybe 4 prongs or something? I so need a friend with a Limited SE model!

After carefully looking closely at both the AR240 and Limited SE models, the AR has the blower button above the keys while the SE does not. Does anyone know where the blower button is located on the 2016-up Limited SE models? I'm trying to see if this could be rerouted.

I am sure you could figure out somewhere to put the blower switch on the 240. It is just two position analog switch. The bigger issue is that the parts cost a lot and even then I don't think they would work. The momentary push button panel (over 200 bucks from yamaha parts dealers) hooks up to a sub computer and the boat control unit (BCU) which is unique to e-series boats and communicates over proprietary can bus, eng can bus, and 5v analog. This then communicates with another e-series only part call the SCU or system control unit which also communicates with the ECU. You may end up spending over a grand just to find out it won't work with re flashing the ECUs and adding the other parts and wiring those computers are looking for. The e-series boats are are example of adding way too much on top of an existing system instead of redesigning from scratch. My guess is we won't see a redesign until they update the engines which would force a new ECU.

You can buy the service manual online that has the wiring diagram for the e-series boats. I am sure you will figure something out. At a minimum you could buy an off the shelf after market car starter and use the button assembly that the e-series boats do but at that price I would just source my own buttons. Interesting that a gps antenna costs $294 bucks from a Yamaha parts dealer when I can buy the exact same one online for $19.99.

That is exactly my (mostly uneducated) feeling about it. I debated FBW (fly by wire) throttles and am still SALIVATING over those anytime I can touch - most recently at the boat show, so smooth, LOL. But ultimately I decided to wait and see -- Yamaha electronic gremlins that I know about are all just about impossible to diagnose and fix on the fly.

I definitely agree with you there. The tricky part is, it's hard to know anything or diagnosis without seeing the diagram. But on the flip side, most ignition systems don't deviate too far away from each other. With the right relay tied into the existing key assembly, there shouldn't be a problem getting this to work. Agreed that the SE panel probably won't work but i was trying to give it as much factory look as possible. Will put this one on to-do list for late spring. This weekend is my last weekend coaching so plenty of time coming for me to mess with things. First get the LEDs and tower squared away.

To be honest @swatski with the wiring diagram in hand on this site, I believe with all the knowledge on here, solutions can always be made. Just sucks when no one knows where wires are going to and all.

I have a 2007 sx230 and am interested in putting a simple push button start on it. I want to hide the keys in the compartment in front of the pilots chair. Maybe you guys can give a input but if I was to do one switch for each engine could I not just take the wires from the start position of each key switch and wire them to the push button. The key would still control the master power but the buttons would then act as the start position of the key switch.

Your sure can do this just as you mentioned. Just tap into the yellow/red and brown wires for each ignition and run those to water proof momentary push button normally open switches. Pressing the switch will be just like turning the key (the engine will crank as long as the switch is depressed). You could also try this and play with the timing for your engines. https://jetboaters.net/threads/push-button-start-mod-it-works-with-video-and-full-instructions.9371/. I honestly like single push button stop better than start which you could do very easily and direct from one switch.
