1. Identify the exact engine.
Record the engine brand, full model designation, production year and horsepower. Keep a photograph of the identification plate available. Horsepower ranges in a catalogue are screening information, not a complete fitment decision.
2. Read the existing propeller.
Record the diameter and pitch marking, blade count, rotation and any part number. If the current propeller has performed poorly or is not the original specification, do not assume its size is the right replacement.
3. Confirm the engine connection.
Check spline count, gearcase size, hub system and required hardware against the engine documentation. A matching diameter and pitch alone does not establish compatibility.
4. Use the finder to build a shortlist.
Combine engine brand, material and dimensional filters. Review the engine notes for each result. A blank catalogue field means the specification needs confirmation; it is not a universal fit.
5. Confirm before ordering.
Send your shortlist with quantities, destination and exact engine details. Availability, packing requirements and delivery arrangements are confirmed in the quotation. For performance selection and operating RPM, follow the engine and boat manufacturer’s guidance or consult a qualified marine technician.
