Formula Lights Average between 60-80 MPHÂ
Â
Speeds vary based on a lot of different factors such as shape and size of the course, weather conditions, water conditions, boat setup, prop choice and more.
Â
The current 1/4 mile straightaway record is 84.905 MPH set by RJ West on Sept 24, 2017
Formula Lights is a stock class and is required to run standard pump gas and not allowed to run special racing fuel. Fuel is tested after each race to ensure no modifications or additives have been used.
Â
Most racers use Recreational Fuel (aka Rec Fuel) which is ethanol free and can be found at many gas stations.  With the Formula Lights running a 2-stroke motor, oil is pre-mixed with the gas as high as a 25:1 fuel to oil ratio. This is much higher than most of the new 2 stroke outboard motors, which typically run a 50:1 or even 100:1 fuel to oil ratio.
The Formula Lights is a stock class and run a stock, 2 cylinder OMC, Johnson or Evinrude 2-Stroke, 44.9 cubic inch fishing motor which can produce around 60 HP.
Â
Being a stock class, no modifications can be made to the motor to improve horsepower or performance
Formula Light Tunnel Boats compete mostly at in-shore venues, such as lakes, rivers, reservoirs and quarries all over the US.

In the 1980’s Formula Light boats were made almost completely from a special type of marine plywood called Okoume.
Â
Most of the formula lights boats you see running today, are from the early 2000’s.  They are a mix of Composites, like Carbon Fiber or Kevlar in the drivers area (safety cell), and wood for the rest of the boat.
Â
Today, with the goal to improve driver safety, yet make a lighter hull, Liquid Revolutions boats are made 100% from composites such as fiberglass and carbon fiber and contain no wood.
