Buying Guide

Confirm engine model and part number

Match your outboard's year, HP and engine code to the kit part numbers to ensure correct impeller and housing fit

Check kit completeness

Prefer kits that include housing, gaskets, and fasteners to minimize additional purchases during impeller replacement

Material and impeller type

Look for neoprene or nitrile impellers and corrosion-resistant housings for longer life in saltwater environments

Compatibility with lower unit service

Choose kits explicitly tagged for lower-unit service or specific outboard models to simplify disassembly and reassembly

Value vs. brand fit

Balance budget options under $50 against mid-range kits that include housings or additional seals for better long-term value
