Sooo after our bimini adventure with a bad engine crossing I am sitting in the passenger set as my bad ass wife whips this semi sized rig through Jacksonville florida like she owns the road looking at my phone researching ecm. What are my options for this ecm if determined that's the problem which I am pretty sure it is. Is a new one at 1200 bucks my only option? Can they be repaired and if so is it worth it? I know I could buy a used ski or something but not sure that's the Wyatt I wanna go.. Any thoughts?
 
At one point on this very forum there was a link to a company that repairs them. Not sure where it is at the moment, but if you incline your seat a little, compliment your wife and then start searching I bet you'll find it before I do!
 
@Ronnie had issues with having his repaired

He had a couple posts but I don't think it was either of those two
 
Isn’t it something like carmo? That does the eco repairs.
 
I have used carmo twice and had no problems u get the see warranty with them as u do with a new one and the turn around is very quick if you had the common injector problem then tell them to go ahead and change all four of the injector ports and u will be all good

No problems with it? How much did it cost? I will prob do both before next year.
 
I used carmo, a little strange in that I mailed from sf area north 200 miles to Chico. When I got it back from Chico it was in a box within a box and the inner box came from Europe, can’t remember exactly where but possibly the netherlands. Anyway mine came was there and back within 3 to 4 weeks of me sending it to them. Its cover was drilled with 20 or so small holes which were filled with plasti dip like material/tape. The told me mine was u repairable. So only I was only out the $30 in shipping costs plus $70 for the diagnostic services. If they could have fixed total would have been under $350. Of you use carmo check there site to see if they have repaired you model before. FYI They list or listed a lot of motorcycles ecu that they have repaired to.
 
@bronze_10 give me part number I'll check price on new one from Yamaha. Will be cheaper then at a dealer.

I searched their site yesterday while my wife was driving and I found 08 sx230 modle listed in their description as one of the engines they repair.

I'm not sure what the part number is.. We drove in last night at 1205 am drive the truck and trailer straight into the driveway, (no backing it in ) and walked inside. Lol. I'm gonna have to work yo get the fam to help me get it all cleaned up today. Once that's done I will try to start looking at the engine. Prob Monday. I looked on yamaha on yamaha sports plaza. Com yesterday and to my surprise there were several different types of 08 sx 230. Excluding the car modes there are,

Stx230Cg, stx230Dg, stx230eg

I don't know what the letters at the end mean. They may all use the same ecu.
 
Another thing to keep in mind is that the ecm does not have to be the exact part number that you currently have. If you get one for the same hp engine that should work. This is per the jet ski rental company owner and repair guy I sold my a man fx cruiser with a bad ecm to. He called after the sale to confirm that a different part number ecm from a different year ski worked In The one I sold him. In your case one from any 230 ho 160 ho powered boat or similarly powered fx wave runner should work. Still, If you end up going used buy one that is refundable.
 
My buyer said he took one out of annother year ski and it was plug and play.
 
Would not surprise me if both ECUs had the same flash--maybe Yamaha kept two part numbers to reserve the right for minor differences if needed. Would be interesting to put YDS on the Waverunner ECU after it's been run on the boat for a while to see if any error codes are thrown.

Unfortunately the used FXHO ECUs don't seem to be cheap on eBay either.
