Yamaha SOLAS Impeller Housing

Upgrade to a full stainless steel wear ring! Unlike the original Yamaha design, which uses a cast aluminum ring with a thin stainless liner prone to corrosion and swelling, this stainless steel housing is fully corrosion-resistant. It won’t react ensuring smoother performance and longer-lasting reliability.
