Questions & Answers

Is this a genuine original part?

This is a premium quality aftermarket replacement part from Westway Lubricants, designed to meet the performance and durability standards of OEM tools.

How do I know if it is compatible?

This pump includes all three major adapters (3/8", M8, and M10). If your outboard or sterndrive was manufactured by Mercury, Yamaha, Honda, Suzuki, or Tohatsu, this pump is guaranteed to fit.

Does it fit the 5-liter or 4-liter bottles?

This specific model is designed for standard 1L (liter) and 946ml (quart) bottles with a 28mm cap diameter. It will not fit wide-mouth 5L containers without a secondary adapter.

Note: Always ensure the vent plug is open and the fill screw is removed before attempting to pump oil into the gearbox. Verify your drain plug thread size against the provided specs if using on vintage or rare engines at 4boats.co.uk.
