Hey guys, wanted to run this by y'all.
2006 Centurion Elite V
Mercruiser 350 mag mpi
When cold, boat has a rough idle that surges a bit and makes the boat difficult to run for a few minutes until it warms up. Symptoms are at idle only. With some throttle, she runs smooth. As soon as she drops back down to idle, rough.
Once warm, idle is PRETTY good. Maybe not perfect, but good.
So, Idle Air Control Valve? I don't want to spend $80 on parts without some confidence. Do you all concur?
