High performance boats are as unique as the owners that rig and run them. We come to know these people by how they setup, rig, and run their boats. We even remember these people by the events they attend. High performance boating is a culture in its own.

Most people who frequent performance boating events in Florida and Scream And Fly’s message forums have come to know Andy Frost, also known as “Frostman.”  Andy  has been building and racing high performance boats for over twenty years. “Frostman”, as he’s known on our forums, honed his skills in offshore racing, operating the throttles of a twin-outboard Skater 24 in 1986. Feeling the need to go even faster,  Andy moved on to outboard drag racing in the 1980s.

Andy’s current boat is a 1993 STV Mod-VP tunnel boat, powered by a modified Evinrude 3-litre engine. The 500 pound lightweight competition race hull was rigged and setup by Frost. Instrumentation includes a full compliment of Livorsi Marine gauges to accurately oversee engine functions, while a Garmin GPS 168 handles the speed and mapping duties. The STV is dressed in a custom “ghost flame” paint scheme provided by veteran boat painter Bill Birchfield.

The modified Evinrude engine features a custom short shaft midsection crafted by Wayne Taylor of Taylor Marine and Machine. This shorter midsection lowers the STV’s center of gravity, while providing Andy the option to mate a Mercury Sportmaster lower unit to the OMC powerhead in the future as speeds increase.

Other engine refinements include an OMC lightweight V4 flywheel to reduce engine rotating mass for quicker acceleration, custom engine block porting and deck work, and lightened and balanced internal engine components. The top-speed tuned V6 is fed by a modified Holley fuel pump supplying the thirsty large-bore carburetors with high octane fuel at 8.5 psi. These modifications allow the engine the produce an estimated 300 horsepower, which translates to top speeds approaching 120 mph.

Future upgrades include the addition of a Mercury Sportmaster lower unit with a 1.75:1 gear ratio. The Sportmaster is much better suited to the extreme speeds Andy is attaining with the STV, and the higher gear ratio will allow the OMC to flex its muscles more efficiently.
