Choosing the right Yamaha lower unit starts with matching it to your outboard's specifications. Before ordering, make sure you know the following:
Engine Horsepower – Lower units are designed for specific horsepower ranges and aren't interchangeable across all models.
Shaft Length – Selecting the correct shaft length is essential for proper fit, handling, and on-water performance.
Engine Model & Year – Yamaha has produced many outboard variations over the years, so matching the exact model and production year helps ensure compatibility.
OEM Fit and Performance – A genuine Yamaha lower unit is built to factory specifications, providing proper gear alignment, reliable water flow, and long-lasting durability.
If you're unsure which lower unit your outboard requires, simply provide your Yamaha model number or serial number, and we'll help you identify the correct replacement for your engine.

Replacing your Yamaha water pump impeller at the right time is one of the simplest ways to protect your outboard from overheating. As a general guideline:
Replace the impeller every 12 months or every 100 engine hours, whichever comes first.
Inspect it more frequently if you regularly boat in saltwater, sandy conditions, or shallow water, as these environments can cause the impeller to wear faster.
Watch for warning signs such as reduced water flow from the tell-tale, higher engine temperatures, or overheating alarms. These are often signs that the impeller needs immediate attention.
Check the complete water pump assembly during routine service to ensure the cooling system is operating efficiently.
A new Yamaha water pump impeller helps maintain proper engine cooling, improves reliability, and reduces the risk of costly engine damage, giving you greater confidence every time you're out on the water.
