I believe the 1.5L Optis were having rattling noises from lower unit or prop around idle speed

I have over 2900 hours on smartcraft monitor on my 2005 75hp Opti. Been trouble free except for occasional stalling at idle in gear way back in its life.
Have the idle rattle in prop area mildly.
Tweaked ecu and 90hp throttle body restrictor as soon as warrantee ran out. Never babied the throttle, run it hard almost every weekend.
Awesome motor
