• New letter was faxed to us from GLM Marine tech service rep Dennis along with new aftermarket Johnson drawing in the hope of making it easy to look up and purchase GLM Marine aftermarket products.

• The first Evinrude and Johnson V6 outboard was introduced in 1976. These engines were in production (with few changes) for 16 years (until 1992). The engine was basically a 90 degree crossflow V4 with two additional cylinders added to the top. Two separate 3-cylinder ignition systems were employed. The engines were available with three individual two barrel carburetors were never available with fuel injection and can be identified by the removable transfer port covers and deflector dome on the top of the pistons.  They have been available in six different horsepower versions; 150,155,175, 185, 200, and 235

The increased horsepower of the V6

• Outboard engines required a much stronger lower gear housing. The large diameter V6 gear housing ( that was eventually used on the higher horsepower V4 outboards and the V6 and V8 sterndrives ) was also introduced in 1976

• For the 1986 model year Evinrude and Johnson introduced a new 90 degree V6 engine.  The engine design has been very successful and has been in production for 20 years. The new engine was basically a 90 degree loopcharged V4 with two additional cylinders added to the top. A loopcharged engine utilizes a sophisticated transfer port design and a lightweight flat top piston for dramatic horsepower increases.  The V6 loopcharged engines have the horizontal reed valves and were available with three individual two barrel carburetors or fuel injection.  A 90 degree loopcharged engine can be identified by flat top pistons and do not have removable transfer port covers. They have been available in four different horsepower versions; 185, 200, 225 and 250.
