The Mercury / Quicksilver 19453Q2 is a genuine OEM water pump impeller repair kit for Mercury and Mariner outboard motors from 30HP to 75HP. Keeping your water pump in top condition is one of the most important maintenance tasks on any outboard — a failed impeller means no cooling water and a seized engine.

Why Replace Your Water Pump Kit?

• Impellers degrade over time and with heat cycles — recommended replacement every 2–3 years or 300 hours
• A worn impeller reduces cooling flow, risking overheating and engine damage
• Genuine OEM kit ensures correct fit, materials, and performance
