The St. Pete Powerboat Grand Prix was the seventh round of the 2021 APBA Offshore Series.


The SV Offshore team has re-powered it Outerlimits 39 Supercat with the new Mercury Racing engines to demonstrate the performance and long life of the naturally aspirated 9.0-liter V8 competition engine. Designed to be to be powerful, durable and reliable on 89 octane (Rec 90) pump fuel, the 860 Competition features race-proven Mercury Racing aluminum four-valve cylinder heads and dual overhead cams greatly enhance performance and durability over a standard two-valve design. SV Offshore Racing principal Vinnie Diorio is on a mission to sway his SuperCat colleagues to adopt the 860 Competition engine for the future of the class. 


Diorio and his Canadian teammate Simon Prevost arrived in St. Pete fresh off of an impressive second-place performance at the Great Lakes Grand Prix in Michigan City, Ind. In St. Pete, the duo would be faced with extreme heat and humidity — a vast difference from the temperate climate of Lake Michigan. On Saturday, SV Offshore set out on a comprehensive test program, evaluating the boat’s set up for the sea conditions and course layout, which had more turns than most on the 2021 offshore racing calendar. At the conclusion testing, Diorio and Prevost returned to the dock pleased with the boat’s performance, and reported no reliability concerns.


The stage was set on Sunday race day with even hotter conditions. Diorio, who also throttles the LPC Racing SuperStock class boat powered by two Mercury Racing 300hp outboards, jumped onto his SV Offshore Outerlimits just before the start flag dropped. Diorio and Prevost raced SuperCat entries M.CON Racing and Chariots of Fire to the first turn. Eleven laps and 66 miles later, SV Offshore crossed the line second overall to the M.CON Racing Skater entry.
