New Outboard Motor Firing on All Pistons

About this technology

Overview

By adopting a high-strength, wear-resistant aluminum alloy from NASA for its latest product line, Bombardier Recreational Products Inc., has created a boater's dream: the first outboard motor engine that will not require oil changes, winterization, spring tune-ups, or scheduled maintenance for 3 years of normal recreational use. Not only is the new E-TECT engine maintenance-free from such tedious upkeep responsibilities, its piston design successfully reduces the so-called slapping" sound that occurs when pistons slide up and down in the engine's cylinder. The NASA alloy greatly improves piston durability because it is 2.5 times stronger than conventional cast aluminum pistons at high temperatures and can be produced with a material cost of less than $1 per pound. Engineers finalizing the product also saw environmental advantages from the alloy as it would help the new engine comply with the most stringent emissions standards in the United States."
