There are two internationally recognised classes
Class A - Engines in Class A boats are restricted to either 6.7-litre (412 cubic inch) engines with cast iron blocks and heads or 6-litre (365 cubic inch) engines with aluminium heads. Both size engines are only allowed two pushrod operated valves per cylinder. Furthermore the engine must be normally aspirated, using a 4-barrel carburettor. Fuel is 100+ octane aviation fuel. Typically these engines produce up to 650 horsepower
Superboats - Engines in the superboat class have no maximum size but instead have a minimum size restriction. Normally aspirated engines must have a displacement of 6.5 litres (400 cubic inch) or while forced induction (turbocharged or supercharged) engines must be at least 3.8 litres (235 cubic inch) in displacement. These engines typically are fuel injected and run methanol fuel. The small-block engines typically produce 950+ horsepower, while the big blocks can typically produce between 1000 to 1400 horsepower.
Nitromethane and nitrous oxide are not allowed.
