The Albert Hutton Olympus Racing Engine

Created: April, 2009.

This is the Olympus high performance racing engine designed, built, and developed over a forty year period by the late Albert Hutton. Originally conceived as a powerplant for a model hydroplane, it somehow evolved into an experimental unit with more testing and development that was ever envisaged at the start. For more details regarding the engine, its builder, and its development, see the Bibliography at the end of this page.

The engine is currently in the care of MEN Member, Dave Sage (Mississauga, Canada), who has kindly provided the photos that appear below. In 2007, Dave was given costodianship of the engine by Albert's daughter, Elaine Hutton-Willcock. He set about carefully restored the engine by replacing perishable items such as hoses and seals, ultimately returning the engine to its full running glory. Dave now takes the engine to major Model Engineering exhibitions in Canada and the USA where he demonstrates it, drawing large, appreciative large crowds.
