# LEHR, Inc. - Environmentally friendly technology

> LEHR was a Los Angeles clean-engine company founded by sea captain and inventor Bernardo Herzer. It replaced gasoline in small engines with propane, first in lawn tools and then in 2.5-to-25-horsepower marine outboards. A patented screw-in fuel system promised easy starts, no stale gasoline, no evaporative fumes and fewer spill headaches. The products won EPA, boating and magazine awards and reached retailers including West Marine, Home Depot and Ace Hardware. But by 2019 the outboards were no longer being produced, and owners reported that parts and support had become difficult or impossible to obtain - a useful warning that durable hardware needs a durable service ecosystem.
