844902 Seawater Filter | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta seawater filter weighing 0.014 kg and listed for 70 applications across the D, MD, TMD, AD, TAMD and BB series engines. It is grouped under Fuel System in the listing despite its seawater duty, and it shares its fitment count and engine families exactly with bushing 844903, so the two are ordered together on most jobs.

🚤 Compatibility

• Engine Family: D, MD, TMD, AD, TAMD, BB, HS, MS, KAMD, KAD

⚙️ Key Features

• 0.014 kg
• 70 applications across the D, MD, TMD, AD, TAMD and BB series
• Shares its fitment with bushing 844903
• Grouped under Fuel System despite the seawater duty

🔌 Function

Traps grit, shell and weed carried in the raw water so debris does not reach the components downstream.

⚠️ Common Signs of Failure

• Falling raw water flow and rising engine temperature
• Screen blocked with weed, shell fragments or scale
• Gauze torn or split, letting debris straight through
• Screen distorted so it no longer seats in its housing
• Corrosion staining and salt crust around the housing

🛠️ Service Notes

• Order bushing 844903 at the same time — it carries the same fitment and is normally disturbed to reach the filter
• Clean or renew at every seasonal service and after any grounding or run through weed
• Fit new sealing rings when closing the housing back up

📦 Condition

• Genuine Volvo Penta part
• Brand new
• Supplied in original or equivalent packaging
