[kyong1]

After going into limp mode returning to boat ramp and solving the fuel leak and oil from lower unit seals . Replaced fuel
pump, water pump and had done the 300 hr service idle went erratic since .I had attempted adjusting to higher 800rmp .but still up and down..

A 2011 Yamaha F115 is fuel injected. Idle RPM is not adjustable.

If you try to play with something to change the RPM the ECU is going to do its best to make another adjustment to counter what was done.

The yamaha f90 efi i bought this spring had a problem with idling speed before i bought it. It would start in high idle but wouldn't slow down in a few seconds as expected. The shop I bought it from had to replace some electronic idle sensor part and then it idled fine.
