⚠️ WHY IS REGULAR REPLACEMENT CRITICAL?
A functioning impeller is crucial to the survival of your MerCruiser engine! A worn impeller can lead to:
- ❌ Engine overheating

- ❌ Reduced performance and power loss
- ❌ Total breakdown (can cost SEK 50,000+!)
- ❌ Stretched out on the lake
🔥 Prevent expensive repairs – replace the impeller regularly!
💡 EXPERT ADVICE FOR MERCRUISER OWNERS:
- 📅 Replace annually – or every 200 operating hours (whichever comes first)
- 🔍 Inspect the cooling water body – weak jet = warning signal!
- 🧰 Use lubricant – when assembling to protect the impeller
- ⚙️ Replace ALL parts – impeller, O-ring and gaskets at the same time
- 🌊 Saltwater farm? – inspect more often (every season)
- 🔑 KEY Drive – check that the key is seated correctly when installing
- 🚫 NEVER run dry – the impeller will be destroyed in seconds!
🔧 EASY INSTALLATION:
Installation in 5 steps:
- 🔧 Remove the water pump housing
- 🗑️ Clean the pump chamber thoroughly
- 🔑 Install new impeller with key (KEY)
- ✅ Replace O-ring and all 6 gaskets
