3" In-line Blower W/Delphi Connector3" engine compartment blower. This blower has a Malibu installed Delphi connector for plug and play compatibility. This connector will not be found on aftermarket blowers. Some older model boats will not be able to plug into this connector. In that case, cut off the connector and hard wire it in as you would with non Malibu blowers, as this part is still considered the correct replacement by Malibu.
