Questions & Answers
Is this a genuine original part?
This is a premium quality aftermarket replacement part, manufactured to meet or exceed original equipment (OE) standards for fitment and performance.
How do I know if it is compatible?
If your outboard or sterndrive uses a 3/8"-16 or M8 x 1.25 drain plug, this pump is compatible. This covers almost all engines from Mercury, Yamaha, Honda, and Volvo Penta.
Will this fit the larger 2.5-gallon or 5-gallon jugs?
No, this specific pump is designed with a 28mm cap to fit standard 1-quart (32 oz) or 1-litre bottles. Larger jugs typically require a different pump with a wider diameter cap.
Note: Please verify your lower unit drain plug size against the references above before purchasing. Always follow your engine manufacturer's guidelines for gear lube capacity and oil type.
