Good luck finding a used part.

Do you know why the ECU failed? Make sure that the ISC is in good working order. If it fails it can take out the ECU. All too many have simply replaced their ECU, without replacing the ISC, only to have a bad ISC take out the replaced ECU.

typically, a mechanically sticking ISC valve is the reason for the ECU failure.

got twin yamaha 115 ,when i swap the ECU on the bad engine all goes well, idle is fine !! must be the ECU itself??

they are just telling you to look for what caused it to go bad so it will not take out another one

used part dealer

I've used a place called Marine Resources 941-999-4084. I just purchased a ECU from them, they typically charge 1/2 price of what a new part would cost.

In my case the post office, lost item. It has taken some time to get the part to me, however, the owner realized the trouble it caused me and decided to purchase a brand new ECU without upcharging me.

Ask for Derick or Ron.

USE caution when purchasing items from

Aug. 15 2013. I purchased an ECU for a yamaha 115 4s, 2006. Please, use caution if anyone decides to purchase items from Marine Resources, 920 S River Rd, Englewood, FL 34223-3910. (941) 999-4084. To date, I have not received the ECU. I was given several reasons for why the ECU isn't here, but after several contact attempts, they have failed to give me a tracking number or returned my phone calls, after indicating they would get back to me in twenty minutes.
