Buying Guide

Confirm engine fitment

Match your outboard model and horsepower to the kit’s listed compatibility to avoid returns or downtime

Check included parts

Prefer kits that include impeller, housing, gaskets and key fasteners to reduce additional part purchases

Assess impeller material

Flexible rubber impellers resist cavitation and debris better than brittle alternatives for longer life

Look for matched housings

Kits with a housing or matched plate ensure correct clearance and simplify installation and seal integrity

Evaluate brand compatibility

Select kits from brands known for marine parts compatibility with Yamaha, Suzuki, Mercury, Nissan and Tohatsu engines
