Bilge blower question

[Riley1840]

I have a 16 foot Spectrum with outboard motor and built in gas tank. Do I need a vented bilge blower? In first pic cover is removed for floor work, in 2nd cover is on. There is a small space for the bilge pump. It did not come with a blower.

OBs are not required to have a blower

Thank you.

Only on inboards as there is a possible ignition source in an inboard motor where there is not on an outboard.
