Volvo Penta D1-30 Exhaust Elbow, Part Number 861906
This is the exhaust elbow or water injection elbow for the D1-30 diesel series. Exhaust elbows are a common cause of overheating and poor exhaust flow of water out of the transom.
Failure to remove the exhaust elbow, to check it for carbon build-up and rust can result in the engine overheating and a lack of performance. On a D1-30 series, 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. Remember, the outer water jacket, where rust fragments can build up, 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.
