Volvo Penta D1, D2-40 exhaust elbow hose, part number 3812877.
This is an exhaust elbow hose that takes water to the top of the exhaust elbow for a D1-13, D1-20, D1-30 and D2-40 diesel. When changing the exhaust elbow, it is recommended to change the small rubber hose at the same time as it can become hard or perish.
Exhaust elbows are a common cause of overheating and poor exhaust flow of water out of the transom.
Failure to remove the exhaust elbow and check it for carbon build-up and rust can result in the engine overheating and a lack of performance. The exhaust elbow 861906 should be removed at least every 5 years and checked internally for corrosion and blockages. If in doubt, change it using the gasket 861907 and this hose. Remember, the outer water jacket cannot be cleaned due to a lack of access.
It is not uncommon for aftermarket non-genuine elbows to corrode more quickly. We have seen some aftermarket stainless exhausts fracture and explode. A Stainless exhaust should not be fitted to any Volvo Penta diesel engine. Only use genuine Volvo Penta parts to ensure the safe operation of your diesel for you and your family and crew.
