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?

Check your propeller shaft for a 10-tooth spline. This propeller is designed for the standard 3-inch gearcase. If your original part number matches any of the cross-reference numbers above, this part is a guaranteed fit.

Will this 12" pitch improve my top speed?

The 12-inch pitch provides a balance between speed and torque. If you are replacing a lower pitch propeller (e.g., 9" or 10"), you may see an increase in top-end speed, provided your engine can still reach its recommended RPM range.

Note: Please verify your engine's gearcase size and spline count before ordering. 4boats.co.uk provides high-quality components for professional marine maintenance.
