Ken Warby set the world record of.

Fastest boat mph. I believe Darris Allison once said he was concerned with making not the fastest boats but the most efficient boats. Yes a 51-foot canopied Outerlimits with 4000 HP under the hatch and a 43-foot open-cockpit Black Thunder tied for a top speed of 161 MPH at this summers Lake of the Ozarks Shootout in Central Missouri but those are exceptions not rules. A bevy of illogically fast boats wowed the crowds but the most impressive was Brad Rowlands South Bay 925CR Tooned In which clocked a maximum speed of 114mph 99 knots and set a new world record.

The current fastest boat is the Spirit of Australia. Sure there were boats that could run 100 MPH with the XS but the R seems to be pushing boats about 3 to 6 MPH faster and sometimes more. The small Allisons are designed to run lighter engines plenty have older Mercury Racing and other race engines that can push the hulls way over 100 MPH easily.

With a Grand Sport you can run a stock 175 Pro XS and be in the high 80s MPH. The official world water speed record is 27597 knots 51109 kmh or 31758 mph by Ken Warby in the unlimited-class jet-powered hydroplane Spirit of Australia on Blowering Dam Lake New South Wales Australia on 8 October 1978. The Worlds Fastest Pontoon Boat 114 MPH.

The 300R has created a standard where the once elusive 100 MPH mark is now becoming normalized.
