In addition to this, GM Marine introduced the Gen V 4.3-liter small-block V6 for sterndrive applications. Yup, it’s a boat engine, but it’s main design is based on granddaddy 265. Promising greater efficiency and durability compared to its Gen IV predecessor, the new kid on the block received LT1-derived goodies like variable valve timing and direct injection.
The Gen V 4.3L V6 is somewhat similar to what GM offers with the latest-gen Silverado, Tahoe and Corvette Stingray. Before you head on over to read detailed info in the attached release, we would also like to mention that the boat engine boasts with a variable-displacement oil pump, positive crankcase ventilation-integrated rocker covers and an all-aluminum block and oil pan.
