About this part
This page covers the genuine Yamaha part 69MG43110000 (Housing, water pump). It’s an original OEM component designed to match Yamaha’s factory tolerances for correct fit, reliable function, and long service life in marine conditions.
Why choose genuine Yamaha?
Choosing genuine Yamaha OEM helps avoid problems often seen with pattern parts: mis-sized sealing profiles, inconsistent rubber compounds, poor plating, and connectors that don’t lock correctly. On a marine engine, those small differences can become big issues.
Notes for this part
Impellers are a key cooling-system service item. If the tell-tale is weak, cooling flow seems inconsistent, or you’re not sure when the pump was last serviced, replacing the impeller is sensible preventative maintenance.
Installation tip: inspect the wear plate and housing for scoring, and renew any O-rings or seals disturbed during disassembly. Avoid dry starts — ensure the leg is supplied with water before running.
Warranty
Warranty: 1 year on new genuine parts (subject to correct installation and normal use).
Ordering tips
Ordering tip: Yamaha variations can exist within the same year. The safest approach is to confirm the part number against your exact model code / serial range before purchase.
