I am wanting to build (or add) a fan or blower system to my 2002 518. I open my compartment lids every time I pull the boat into the garage but often I am left with a slight damp compartment here and there. I am wanting to build the dry compartment fan system using 1”-2” flex hose. I will then add some vents to each compartment. Has any ever built this system or maybe even purchased a similar system. I know a lot of the new boats have this installed.
