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 boat motor 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 does a 2 hp boat motor go?

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.

## How fast is a 5 horsepower motor?

High Performance. Runs at 5 HP, with a **maximum speed of 3450 RPM**, synchronous speed: 3600 RPM, Voltage: 208-230V, Frame: 56, easy to use.

## What is 55 lbs of thrust in horsepower?

Pounds of Thrust to Horsepower Chart

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

40/45 | 42 | 0.5 |

50/55 | 50 | 0.6 |

70 | 42 | 1.01 |

## 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**.

## How many horsepower is a 35 lb thrust trolling motor?

So every 746 watts is roughly equivalent to 1 horsepower. 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 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.

## What’s the fastest trolling motor?

The fastest trolling motor is one **with 55 lbs of thrust like the Newport Vessel**. It will move a small boat about 4-5 mph.

## How fast does a 10 horsepower motor go?

View Full Version : 10 H.p. = **1.5 M.p.h.**

## How do you calculate speed from horsepower?

Relating Horsepower to Speed

You know the horsepower rating of the engine, and now you know the thrust, so you can calculate the speed the car will travel using the relationship: **Speed = Power/Force**. To arrive at an answer, we note that that 1 Horsepower = 550 ft.

## How many pounds of thrust does a 5 hp outboard motor have?

A 5 hp probably has somewhere near or **over 200 pounds** of thrust.
