ENGINE FIRE ACCESS PORTS
I added two fire-ports to enable extinguishing a fire in the engine compartment without having to opening the engine compartment.
This provides an enclosed environment for the extinguisher chemicals to smother the flames and prevents added oxygen from feed the fire.
I installed one through the companionway steps and one in the aft stateroom engine box cover.
They are made for Osculati and offered by many chandlery shops including West Marine #3734464 from Marine East (#16760) in plastic or stainless.
