Questions & Answers

Is this a genuine original part?

Yes, this is a genuine Attwood Sahara MK2 retail-packaged unit. Unlike bulk OEM versions, it includes the check valve and both straight and 90-degree outlet adapters.

How do I know if it is compatible?

We recommend checking the SKU/MPN list. If you are replacing an older Sahara MK1 (4507 or 4511), the mounting holes are an exact match, making installation seamless.

What is the benefit of the X-Air™ Impeller?

Traditional pumps can trap air in the housing (air-lock), causing them to spin without moving water. The X-Air™ design forces air bubbles out of the pipework so the pump can prime and function instantly.

Note: Please verify your original part number and bilge hose diameter against the references above before purchasing.
