Conversion ???????????/

Fla._Deadheader · November 23, 2003, 06:30:22 AM

I need some technical genius to convert the available HP in an electric trolling motor. Pounds of thrust would be approx. 45. Any takers??? ;D ;D

Jeff · November 23, 2003, 06:56:03 AM

there aint no way to do the conversion with that info. Prop pitch has a lot to do with a thrust rating

Fla._Deadheader · November 23, 2003, 07:12:46 AM

O.K. What do you suggest??? NO prop required.

Bro. Noble · November 23, 2003, 07:34:31 AM

I think ya gotta convert it to seahorsepower then divide by 2,000 ;D

Jeff · November 23, 2003, 08:22:27 AM

no stats on da motor? Manufacture? RPM's volts?

If'n it wuz that simple, I'd a done did it :

;D

Don't know what you need to do with it but my simple mind makes me just try it. :D

That way you find out if its too strong, too weak or jus-s-st right. :D :D

This is toooooo involved to just try it. Too much work

Jeff · November 23, 2003, 10:33:31 AM

Maybe build a dynometer first...

Jeff · November 23, 2003, 10:34:23 AM

You have a trolling motor that has no manufacturer?

Mercury------No size rating----------no torque rating-----------no nuttin else rating

EZ · November 23, 2003, 12:39:57 PM

I have a Mercury 28 lb thrust and in the manual it says equivalent to 3 hp.

See there??? Ask a question around here and SOMEONE has the answer. :D :D :D :D
EZ, you just won a free Monkey Blade. ;)

Jeff · November 23, 2003, 02:23:43 PM

Yea but his was 28 lbs you said 45.

Fla._Deadheader · November 23, 2003, 02:28:26 PM

I CAN multiply to get my answer. :

;D

Jeff · November 23, 2003, 02:39:56 PM

How can you do that? I have a minn Kota that has 28 lbs thrust and its rated at less then 2. I Can add the weed gauard and lose thrust or I can get a different prop that has no weed cutter and gain thrust. I can take the prop off completely and have no thrust but I still have the same H.P. rating on the motor.

I can't see how thrust has any immediate relationship to the horsepower,

Fla._Deadheader · November 23, 2003, 02:58:19 PM

Jeff, We ain't on the same wavelength. The thrust rating I stated was a common number for comparison ONLY. That's the way they are in the store and on some labeling on the motor. That's all I had to go on.
Since I am not pushing a boat, the HP that, even you stated, is what I was after, regardless of how the accessories can change thrust rating. Probably "Torque" would have been a better word than Thrust, but, they ain't listed thata way :

;D
If'n I'da had the amp draw, I cooda used Ohm's Law

Jeff · November 23, 2003, 03:32:15 PM

Well if you say torque we have no problem figuring out horsepower.

Torque * RPM

Horsepower = ------------

5252

Fla._Deadheader · November 23, 2003, 05:10:11 PM

Yer 10000% correct. I have that formula.

DanG · November 23, 2003, 07:49:09 PM

Since Mr. Ohm got his famous law punched through the Continental Congress, enabling us to figger such things, could ya just fire it up, under load, and through an ammeter, and get the current draw? Then ya could take the product of Mr. Voltaire and Mr. Ampere, and give them to Mr. Watt, who could then sell you a horse fer yer power. :P

Who's on first, anyway? ???
