GM Marine Gen V 4.3L V6 Small-Block Engine Promises Better Everything

Throughout history, sailing was to civilization an instrumental element for fast development thanks to trading enterprises done by carriage of goods by maritime ways. Compared to ancient sailing, fabric foils are rarely used in this day and age ‘cos internal combustion took over propulsion duties. The latest in maritime propulsion comes from GM Marine.

When you hear “small-block”, any petrolhead automatically thinks of GM’s small-block engine family, with us since late 1954, when Chevrolet got our attention with the Gen I small-block V8. That simple 265 CID (4.3-liter) V8, churning as much as 195 HP, is genesis for General Motors’ love with the V8 engine.

Introduced on the 1955 model year Corvette to replace the old stove bolt inline six-cylinder, the first of the so-called 3.875-inch bore family is as classy as it gets. Incidentally, the Gen I small-block V8 celebrates 60 years of existence this Mighty Mouse powerhouse got under our skin, here we are today, awaiting the 2016 Camaro to adopt the Corvette’s LT1 6.2-liter vee-eight, pushing an estimated 450 to 460 horsepower.

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.
