HP vs Lb thrust

[gogu392]

Hi Guys,

I will ask a basic question that I know does not have a sharp answer.

I need to know what is the ration between 1Hp and 1Lb thrust

How many Lb thrust is in 1Hp.

 

I understand in the past Johnson motors label the outboards in Lb thrust.

 

I know that the HP and Lb thrust are two different UM (unit measure).

I am just looking for a raw estimate for ideal conditions.

Thank you.

it is very complicated to try and compare (as the above thread suggests)

 

however, in basic practicality, to give you an idea, I have a 17' tiller lund boat with 50hp. Rig is about 1300lbs all said and done.

 

A 2hp outboard will push my boat faster (quite a bit faster actually) than my 80lbs 24v trolling motor ... whether I compare my 80lbs tiller mount tm or my bowmount 80lbs tm.

 

hope that helps a bit...

You simply cannot compare the two mathematically; one is a unit of power and one is a unit of force. Without a time or velocity component, the two are like comparing apples and oranges.

That 2Hp comparison I was looking for.

Thank you.
