    Rough Idle and RPM loss

    Ok my issue is with a 05 Wake 155. After engine warm up idle drops to 1000 RPM and get very rough, plus I get a MAINT message on my display. The engine also tops out at only 6400 rpm vs the normal 7600. I have replaced all plugs twice, and replaced all coils and done all the preseason maintenance. I am stumped on this, with a dual issue problem. Tips?

    I had similar issue with my spark plug coils. Replaced them and solved my issue I'm sure there's a way you can check them

    How old is the battery? It could be all caused with low voltage issues. Load test the battery and make sure its good.

    battery is 9 months old, looks good I had a hard time starting on it on the river and it cranked the engine for over 30 seconds till I got the ski started.

    broken arrow ok
    Press the mode button 5 times for codes...i would run a compression check on the motor to make sure you have good compression...sea doo had had some issues with ecu on those models too...
