Buying Guide

Confirm engine make and model

Match the kit to your exact outboard model and horsepower to ensure correct impeller size and housing fitment

Check included components

Prefer kits that include the impeller, housing or gasket, O-rings, and necessary fasteners to avoid extra purchases

Choose compatible materials

Silicone or neoprene impellers and corrosion-resistant housings extend service life in saltwater environments

Look for serviceability

Kits that mirror OEM mounting points and clear installation notes reduce installation time and alignment issues

Consider horsepower range

Some kits are specific to narrow HP bands (e.g., 40–60 HP or 8–9.9 HP); ensure the kit covers your engine’s power rating
