gogu392 Posted November 30, 2015 Report Share Posted November 30, 2015 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.

Steve Posted November 30, 2015 Report Share Posted November 30, 2015 (edited) 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...

G.mech Posted November 30, 2015 Report Share Posted November 30, 2015 (edited) 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. Edited December 1, 2015 by G.mech Link to comment Share on other sites More sharing options...
