It has set a top-speed record of around 1087 mph with an onboard passenger and a 300 HP Mercury engine.

Fastest boat horsepower. Naturally all the boats are bass boats the closest thing to performance boats in the mainstream world. Taking 5000 divided by 300 gives you a result of 166 pounds per horsepower. This phenomenon called prop riding further reduced drag.

The water speed record was recorded on October 08 1978 at Blowering Dam in New South Wales Australia. The current fastest boat is the Spirit of Australia. Powered by an Allison V-1710 aircraft engine the boat was built by Seattle Chrysler dealer Stanley Sayres and was able to run 260 kmh 160 mph because her hull was designed to lift the top of the propeller out of water when running at high speed.

Shaft horsepower is to be the actual uncorrected engine horsepower less drive train losses. Since we cant test ourselves it will be interesting to see the different setups different props and how fast some of these boats are going. Doing the opposite calculation taking 300 divided by 5000 gives you a result of 006 horsepower per pound.

Lets say for example your boat weighs 5000 pounds and it has a 300-horsepower engine. Built 496 cubic inch big block chevy. Lets look at the Yamaha 150 VMAX SHO Evinrude G2 150 HO and Mercury 150 Pro XS.

The XS-2003 Allison GrandSport is the gold standard for small single engine family boats. Both are exceptionally fast. Allison XB-2002 Bass Boat holds the fastest bass boat record globally owing majorly to its lightweight yet highly efficient construction.

10 - 13. Problem Child Problem Child may be an understatement for the fastest nitro drag boat in the world that boasts an incredible 8000 HP and can reach speeds of 262 MPH in just 35 seconds. Allison makes a slightly smaller boat the SS-2001 SuperSport but the GrandSport offers a little more room and usability.
