Volvo Penta D1-30, D2-40 exhaust hose clamp.
This is an exhaust elbow hose clamp for the hose, part number 3812877 that takes water to the top of the exhaust elbow for a D1-30, D2-40. 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.
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 the hose on a D series, part number 3812877. 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.
