Outboard engine manufacturers Brunswick and Bombardier Recreational Products have both posted test data about their latest outboard engine models that were obtained from testing on the same model of boat. We briefly review this data.
The engines under test were the Mercury-brand VERADO 350 and the Evinrude-brand E-TEC G2 300. The test boat was a RANGER model 2510. Each manufacturer has published the test data on their website.

Bombardier Evinrude E-TEC G2 300 on RANGER 2510, see:
http://www.evinrude.com/Content/Pdf/neutral/performanceReports/ 1131_G2_300HP_Ranger2510Bay_Bay.pdf
According to the data in the reports, the tests were conducted only three days apart, and according to an observer familiar with the testing, the weather conditions during the tests were very similar. The test data both report the air temperature was the same during the tests (at 72-degree-F).
Perhaps the most interesting data to compare in these tests is the top speed obtained, the rate of fuel flow, and the fuel economy in MPG. Here is a summary of that data:
TOP SPEED
VERADO 350 = 52.3-MPH at 6,400-RPM
E-TEC G2 300 = 52.65-MPH at 5,650-RPM
FUEL FLOW at full throttle
VERADO 350 = 29.2-GPH
E-TEC G2 300 = 23.7-GPH
FUEL ECONOMY at full throttle
VERADO 350 = 1.8-MPG
E-TEC G2 300 = 2.22-MPG
A simple analysis of the above data shows that the E-TEC G2 300, while being rated for 50-HP less than the VERADO 350, nevertheless pushed the same boat to a higher speed, while consuming less fuel, and producing better fuel economy.
It may also be worth mentioning that the E-TEC G2 300 is not a special model. Evinrude has announced that it will be introducing a more powerful version of this engine called the E-TEC G2 300 R.A.V.E. which will be intended to provide even better performance due to use of special tuning of the exhaust system. The Mercury 350 is sold through the Brunswick Mercury Racing operation, but is still considered to be a standard consumer model.
It may also be worth mentioning that the Mercury VERADO engine had the benefit of using a Mercury ENERTIA ECO propeller. The Mercury ENERTIA ECO propeller has been hailed as a "miracle propeller" that produces improvements in top speed and in fuel economy compared to other propellers that can be greater than 40-percent, that is a 1.4:1 ratio, and has been specifically mentioned to have obtained these improvements in comparison to a MIRAGEplus
Unfortunately, the Evinrude E-TEC G2 engine was tested with a BRP REBEL propeller. The REBEL has been described as "a tame, elephant round eared prop with little rake". It has also been claimed that the REBEL is nothing but "a copy of the MIRAGE PLUS Propeller." It has also been claimed that the MIRAGEplus propeller is "obsolete." (This is clearly false as the MIRAGEplus continues to be made, but the innuendo is that the design is obsolete.)
In spite of the considerable handicap of the E-TEC G2 300 having been tested with the REBEL propeller while the VERADO was able to use a miracle propeller, and in spite of having a horsepower rating of only 300 compared to the 350 rating of the VERADO, the test results show the Bombardier Recreational Products E-TEC G2 engine to have better top speed, lower fuel consumption, and better fuel economy at full throttle than the Brunswick Mercury VERADO 350.
In is also interesting to note that the E-TEC G2 300 runs on standard [87-Octane] fuel, but the VERADO 350 requires 91-Octane premium fuel to produce "premium performance."
Details of the fuel used in the testing are not explicitly provided.
