🔧 Product Description
Genuine crankshaft-driven flexible-impeller seawater pump for Volvo Penta 7.4-litre and 8.2-litre petrol marine engines.
🚤 Compatibility
Typically suits:
- Volvo Penta 7.4GiPEFS
- Volvo Penta 7.4GSiPEFS
- Volvo Penta 8.2GSiPEFS
⚙️ Key Features
- 7.4L and 8.2L petrol-engine raw-water pump
- Crankshaft-mounted drive
- Flexible-impeller construction
- Current replacement for earlier Volvo pump references
🔌 Function
The pump supplies raw water to the engine cooling, oil-cooler and wet-exhaust circuits.
⚠️ Common Signs of Failure
- Low raw-water discharge
- Impeller damage
- Shaft-seal leakage
- Bearing noise
- Pump-body corrosion
- Loose crankshaft mounting
🛠️ Service Notes
- Establish why the old pump failed before the new one goes on — debris, a blocked strainer, a starved supply or a dry run will take out the replacement just as quickly
- Fit new gaskets, O-rings and seals on the pump's joint faces and drive, with the faces clean, and use only the sealant the workshop manual for your engine specifies
- Check the drive and the shaft it runs on — coupling, gear, key, belt or drive dog — while access is good, and renew anything doubtful
- Prime or fill the pump as the manual for your engine directs, bleed the system afterwards, and confirm it is actually delivering before the boat leaves
- Tighten mounting and cover fasteners evenly to the manual's figures; pump housings distort easily, and a distorted housing either leaks or binds
