2013 DF140 engine skipping during acceleration

[Moonlighter]

If the new SS prop is gripping really well, you could try lifting the motor one hole, because porpoising is often due to an engine set too deep.

Did you ever have the throttle body and/or the ECU replaced on your engine under warranty? My 2013 DF140a experienced a similar stalling when it was returned to neutral idle, and the mid-range RPM surge as you describe. This occurred even when the engine was near-new

I did not have a check engine light or any miss (skip)

A new ECU and throttle body under warranty solved the problem.

ECU and Throttle body are finally getting replaced. The engine will not crank unless you throttle it up. IAC never opens and there are no codes present. I hope this fixes my mid range skip as well. I mentioned this to the dealer a year ago and they knew nothing about this being an issue with this year model.

Could you please be so kind and help me in this matter. I am getting an error code for the O2 sensor. Model number is the one you mentioned ie 18213-98J20. Does it have to be replaced with 18213-98J30? Outboard is still under warranty and sensor was changed already but it seems i got the same model (18213-98J20)as issue arose again. Thanks and appreciate if you could help.

If your motor is out of warranty, does Suzuki still cover this?

Thanks,

There is only one way to find out - talk to your local Suzuki dealer.

Let them know that you are aware that there is a service bulletin out about this and ask that they carry out the replacement free of charge, as its a well known design fault.

It will depend on how your countries Suzuki distributor deals with this type of issue, and it will depend on your countries product warranty laws.

Thank you. I am trying to find a 14mm slotted socket tool now to remove the old sensor and install the new part. Any suggestions are appreciated.
