## How fast does a 2.5 hp motor 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.

## How many HP is 55lb thrust?

Using this formula the popular Newport Vessels NV-Series 55lb Thrust Trolling Motor is rated as 624 watts at the highest forward speed and so 624/746 = 0.84 and would be roughly equivalent to a 0.84 horsepower motor.

## How much thrust does a 3 hp outboard motor 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.

## How many HP is 30lb thrust?

Pounds of Thrust to Horsepower Chart

Pounds of Thrust (lbs) | Amps | Horsepower |
---|---|---|

30 | 30 | 0.36 |

40/45 | 42 | 0.5 |

50/55 | 50 | 0.6 |

70 | 42 | 1.01 |

## 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).

## Is 2.5 hp outboard enough?

The latest models of the 2.5HP outboards are the tiniest you can get. 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.

## 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 many pounds of thrust do I need for a trolling motor?

General rule of thumb: you need at least 2 lbs. of thrust for every 100 lbs. of fully-loaded boat weight (people and gear included). If things like wind or current are major factors where you fish, you’ll want a little extra thrust.

## How fast will a 70 lb thrust trolling motor go?

A 70lb thrust trolling motor will have a speed of about 8 miles/hour or 15 km/hr.

## How many pounds of thrust does a 6hp outboard have?

Thus for a propeller designed for 3 kn speed (typical electric system) the thrust is ~50 lbs/HP, but for a 6 hp outboard designed for 6 kn it would be less than 30 lbs/HP.

## How heavy is a 5HP outboard motor?

The Suzuki 5HP is the lightest petrol outboard on test at just 25kg, which makes a big difference when lifting it.

## How do you calculate thrust 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).

## How do you calculate pounds of thrust?

Divide the converted horsepower by the velocity to calculate the thrust. For this example, 330,000 lb. ft/minute divided by 40 feet/minute equals 8,250 lbs. The thrust is 8,250 lbs.

## How do you convert pounds of thrust to horsepower?

Thrust to Horsepower Calculator

- Formula. HP = T * V / 375.
- Thrust (pound force)
- Velocity (miles per hour)
