What should idle speed be? Can it be lowered ?
05 Seadoo engine and electronics in gprxp idle speed around 1800 rpms AFR at idle is 11 ( rich ) but it is cooking across the water at idle speed with 15-26 prop. Anyway to lower the rpms or just have to live with it and explain to Opie thats as low as it gets?
Will be ordering a powercommander to take some fuel away at idle to get it where it should be. Today was first day on water. Have an idea the 26 prop will be too big and I'll need to re-prop also but havent done any WOT passes yet to get max rpms for baseline.

3-4mph is about as slow as they go stock, I dont know what all you have done to yours but with a 15/26 prop it cant be stock

idle is 1800 and it cant be changed using a stock ECU.

Yeah did get it on the water. None of my switches are mounted and few esthetics things to clean up but I was pretty anxious to get it wet. Since I was the only one on the water (drizzling and not a single boat/ski at landing) just put about 8 miles on it cruising back and forth ramp mostly 30-70 then went back to landing, loaded up , checking hose clamps and stuff about to leave when Mike showed up with pontoon boat. ( he usually rides standups)
With him on the water in case of problem, dropped it back in and went few more miles. I stabbed the throttle open for couple seconds to check boost pressure, rpms and afr.
