Yanmar 3JH, 4JH Exhaust gasket, Part Number 129472-18090

Yanmar replacement exhaust gasket for the 3JH and 4JH Yanmar diesel engines. 

Genuine Yanmar exhausts should be removed every few years and checked for carbon build-up and corrosion. We strongly advise replacing a genuine Yanmar exhaust with another genuine exhaust, as these are critical to the safe, reliable operation of your engine out at sea. Never run any Yanmar for long periods out of gear or at low revs, as this leads to a build-up of carbon within the exhaust elbow, blocking the ability of the engine to breathe. 

This elbow for use with this exhaust gasket is 129670-13561

Fits:  3JH and 4JH series.

3JH2E, 3JH3E, 3JH4E, 3JH5E, 4JH3E, 4JH4E, 4JH5E
