I ordered two of these 4" fans to move air into the cab of my '63 VW van when the vehicle was stationary or not moving fast enough to create adequate air flow. These fans are not silent but they are quieter than the VW original ambulance fans that I was duplicating. They make the equivalent air force as driving about 50 kmh. I was not using hoses so I trimmed the length of the fan housings to fit the air box. The fans are marine rated so a slight amount of moisture entering the vent should not be an issue...12 volt computer fans would not be able to cope with any moisture. These fans work well although I am not using them as intended by the manufacturer.

Looks virtually identical to the original in our bow rider. Same screw spacing so no new holes required. If it lasts the 20 or so years that the original did we'll be happy campers.
