Quick Answer: How fast is a 2 5 hp engine

How fast will a 2.5 hp outboard go?

Tohatsu 2.5 Two-Stroke ($630; www.tohatsu.com) power: 2.5 hp weight: 26 pounds top speed: 5.4 mph noise at full throttle: 84 dB-A. The Tohatsu 2.5 was the only two-stroke we tested. As expected, it’s the lightest and least expensive.

How fast is a 5 hp boat motor?

limit of 6 knots. 5 is about the maximum rated power for the boat. It probably depends what you mean by plane. We were not bouncing along the top of the water, but were well over displacement speed.

How much thrust does a 2hp Outboard have?

Not many supposed 2hp engines could generate more than 40-50 lbs of thrust because of their high propspeed and small prop.

How many pounds of thrust does a 2.5 hp outboard motor have?

The rule of thumb I go by is 1 HP = About 22 lbs of thrust. So it’s about 55 lbs of thrust for 2.5 HP.

How fast is a 3 hp outboard motor?

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).

How fast will a 4hp outboard go?

A 14 foot boat designed as a planing hull might get up to 6 or 7 miles per hour. If it’s a four cycle motor it will be a heavy weight in the back end. Make sure the gas hose is long enough to place the tank way in the front.

How fast is a 6 hp boat motor?

Mercury 2015 6 HP max speed = 16,25 MPH – 26 Km/h -14,4 knots – YouTube.

How fast will a 9.9 hp outboard go?

Assuming this is a light 14′ utility boat and a standard 9.9, Mercury would recommend a 8.5 to 9.5 pitch prop for the OP’s application and predicts a top speed around 20 mph. In my experience with similar craft and outboards, this sounds very reasonable.

How many pounds of thrust is 1hp?

The difference between Thrust and Horsepower Explained

First, pounds of thrust is a static force measurement while horsepower is 550 ft-pounds of work per second, a measurement per unit time.

How many HP is 55 lbs of thrust?

If you’re getting the full 55 lbf of thrust at this speed, then your hull has 55 lbf total resistance at this speed. 55 lbf = 0.245 kN, so (0.245 kN)*(1 m/s) = 0.245 kNm/s = 0.245 kW. That’s about 1/3 hp.

How fast is 30 lbs thrust?

In fact two 55 pound thrust motors will not move you any faster than one 30 pound thrust motor. Higher thrust 12V trolling motors are designed for bigger heavier boats with larger payloads. The maximum speed of a trolling motor is 5 mph regardless of how many pounds of thrust.

Does more thrust mean more speed?

Thrust is simply a static measurement of pushing or pulling power, and higher thrust does not necessarily mean greater speed. Speed is a factor of prop pitch and motor R.P.M. Given motor R.P.M. under load, and Minn Kota’s 4″ prop pitch, the approximate speed that a motor will push/pull a small boat can be calculated.

How fast will a 55 lb thrust trolling motor go?

Assuming perfect riding conditions, the use of the best fuel i.e. the distillate marine diesel, and moderate load, 55-pound trolling motors are likely to attain a maximum speed of only 5 miles per hour. This would take around two hours for the deep cycle battery charge to get completely depleted.

How much thrust is in a horsepower?

description. 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).

What is the difference between thrust and horsepower?

Thrust is a force; it’s measured in units such as pounds or kilograms. Horsepower, on the other hand, is a unit of power (equivalent to a certain number of watts).
