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?

We recommend checking the spline count on your propeller shaft (must be 10 teeth) and the gearcase size (3 inches). If your current part number matches any in our cross-reference list, this is the correct fit.

What if my engine is a Mercury "Bigfoot" model?

Mercury Bigfoot models typically use a larger gearcase with a 13-tooth spline. This 10-spline propeller will not fit Bigfoot models; it is designed for standard 3-inch gearcase applications.

Note: Please verify your original part number and spline count before purchasing. Available exclusively at 4boats.co.uk.
