How fast is a boat with 3 300 hp motors?
When equipped with 250-hp or 300-hp outboards, these types of aluminum fishing boats can typically have a WOT of 55 mph to 60 mph, or a bit more with two people aboard. But you don't have to put engines that large and expensive on a 16' to 24' aluminum fishing boat.6 nov 2018
How fast is 2.5 hp outboard?
5 Four-Stroke ($940; www.yamaha-motor.com) power: 2.5 hp weight: 38 pounds top speed: 5.4 mph noise at full throttle: 87 dB-A.1 oct 2003
How much thrust does a 3 hp outboard have?
A 3 hp outboard will blow a 50 pound thrust electric motor out of the water - I have both and can make that statement. I can hold the boat with the 3 hp running so it isn't pushing a tremendous amount. A 5 hp probably has somewhere near or over 200 pounds of thrust.12 ago 2009
How fast will a 3hp outboard go?
To give you a simple reference, a 3 hp electric outboard can push a 12 ft boat with 150 kg (331 lbs) load at a max speed of 9 km/h (5.6 mph). That's to say the 3 hp outboard motor can provide more than sufficient propulsion for a 10 ft tender or work as an auxiliary power for a daysailer of up to 1.5 tonnes (3307 lbs).13 nov 2020
Why do boats have 3 or 4 motors?
A two-stroke motor has an impressive acceleration and hole shot speed. These days, four-stroke motors have overtaken a two-stroke engine's speed advantage. Acceleration time from idle to full throttle mode in a four-stroke engine is significantly better. They also reduce torque.8 mar 2019
Are outboards faster than Inboards?
More Efficient Power Pound for pound, outboards deliver more power and speed than inboards. Outboard boats are several hundred pounds lighter, and less weight means your boat is faster, easier to tow, and more fuel efficient.19 mar 2020
How fast is a 2 hp outboard?
Honda BF2 Four-Stroke ($920; www.honda-marine.com) power: 2 hp weight: 29 pounds top speed: 5.3 mph noise at full throttle: 95 dB-A. The Honda BF2 employs a centrifugal clutch, which allows the engine to idle without moving the boat and automatically engages the prop as the RPM rises.1 oct 2003
Is 2.5 hp outboard enough?
They're the least expensive gasoline outboard you can buy. ... They're light enough to carry in one hand. They're simple enough to maintain and do most repairs with common tools.
Ok. Now the normal cruise speed if the B737–800 is a maximum of Mach 0.82, which at the altitude and temperature (the speed of sound is related to the temperature) is around 473 knots or 551 mph. So for every lb of thrust used at 551mph, that results in 551 divided by 375 = 1.46 hp.
How do you convert horsepower to thrust?
Thrust horsepower of jet engines and rockets is equal to the thrust in pounds force times the speed of the vehicle in miles per hour divided by 375 (which is equal to one horsepower measured in mile-pounds per hour).
