Product Specifications and Features
MAR076 is an aftermarket cast marine exhaust elbow for selected MerCruiser inline 4-cylinder petrol engines. It is the late-style elbow family commonly used on GM 2.5L, 3.0L and 3.0LX engines from 1982 onwards, and it is primarily cross-referenced to MerCruiser 12076A2, 12076A1 and 76325A2, plus OMC / Bombardier 0509530.
This part routes exhaust gases and cooling water away from the manifold into the exhaust outlet system. On MerCruiser 4-cylinder applications, this elbow family is commonly described as the late round-outlet / new-model elbow used with the later exhaust hose bellows arrangement. Because Mercury cataloging can split this system between 76325A2 and 12076A2.

Fitment Notes
