100 MPH Club

To celebrate the type of power and speed that he makes possible, Leon started the 100 MPH Club. This is an elite group of boaters capable of 100 mph and over. The club now has more than one hundred members. If you are ready, Leon and his highly trained team can take you there.

Customized Power

Derebery Performance is in the business of creating greater power to satisfy your need for speed. You may want to bring in your engine for custom modifications. Beef it up with specially built blocks and heads, or enhance it with custom cams or exhaust systems. Whether building a new engine or modifying an existing engine, Derebery can skillfully put together the right parts to produce a more powerful, reliable engine.

High-Performance Engines

For maximum performance, a custom-built engine is the way to go. Leon likes to call it 'performance beyond reason' in light of the impressive power of his own boat B'yond Reason. While stock engines rarely exceed 900 horsepower, Derebery custom builds power b'yond that - from 350 to 700 cubic inch engines producing from 500 to 1,200 horsepower. Derebery can even double your horsepower with a twin-engine setup or beyond.

The options are endless: supercharged, naturally aspirated or fuel-injected engines. Leon worked closely with PFM to develop one of the first fuel-injection systems for a supercharged engine. With his experience in research and development, Leon and his team can custom design a fuel-injection system for any application. You may either have an engine custom built for your boating needs or choose from the huge selection of high- performance engines already in stock.
