How much thrust does a 15hp outboard have?
A typical displacement vessel with a 15 hp motor will have a thrust of about 200 kg. If you put a typical 15 hp outboard on that displacement boat, it will have much worse performance, since a 15 hp outboard is designed for 15-20 kn speeds.
How many HP is 55lb 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 much thrust does an outboard motor have?
As a rule of thumb 72 to 75lb. of thrust roughly equals one horsepower or 746W of electrical power. A typical 12V motor that draws 60A consumes approximately 720W. The equation for power is easy: the higher the voltage, the higher the thrust.
How much 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 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.
How fast is 2.5 hp outboard?
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.
How fast is a 2.5 hp outboard?
Here are our results. 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.
How much thrust does a 1 hp trolling engine have?
And here we mainly discuss the pounds to thrust on the boating field with a relatively limited thrust range commonly seen as below and not the jet engine field. So 1 hp trolling motor basically equals to 70 lbs of thrust, and about 0.6 horsepower is a 55 lb thrust trolling.
How many pounds of thrust is equal to 1 hp?
For an average trolling motor, figure towards the high end of this scale. If using a better prop, then comes with the typical trolling motor, then the some place in the middle. The 105 pounds of thrust, 24 volt motors are about a single HP.
How many horsepower does an outboard engine have?
The 8- to 15-horse models round out middle section of that range, but notably missing is a high-thrust model. You might be surprised to find out that two-stroke innovator Evinrude sells four-stroke outboard engines at all, much less a portable four-stroke outboard range starting at 3.5 hp and moving up to 15 horsepower.
How much thrust does a 24 volt motor have?
The 105 pounds of thrust, 24 volt motors are about a single HP. I know formulas vary , but I always use 20 lbs for most boats , 25 for really good prop setups and 30 as the dream of “perfect”.

How many lbs of thrust is equal to 1 hp?
Ok…so if I have a BOLLARD PULL table of actual empirical yields of motors, say from 2-50 horsepower, with common OEM props on each (say 72% efficient), then I should be able to ideally convert outboard (gas motor) thrust to electric motor thrust, if the actual push or thrust of such electric motors is being reported truthfully as a bollard value.
