fogging my engine

[drfish18]

I have 2/225hp yamaha s salt water series 1999.
My question is where are the intake manifolds located so I can fog my engines for winter storage? I have done routine maintenance on my engines but have never fogged my engines.

just remove the air silencer bolted to front of carbs or throttle body if it's an EFI and spray fogging oil in carbs.
