I'm attempting to learn some things and am having trouble wrapping my head around a few concepts. Strictly talking about usable thrust and how it relates to a boats movement.
On one hand we have an 80lb 24vdc trolling motor. pulls 54 amps at roughly 1000rpm and produces 80 lbs of thrust.
On the other we have a Thruster. same 24vdc and 80lb thrust, it however produces 3500rpm at almost 200amps.
Why is the thruster so much more power hungry and what does it give me? I've asked a couple of thruster manufacturers and they basically say it just does. Higher rpm = more thrust. Yet when I tell them the trolling motor produces the same thrust at a lower rpm and a fraction of the amperage, they just skoff at me.
I gave one Dealer the example, "if a boat were floating in a dock against a scale, That scale should read 80 lbs with either the trolling motor or the thruster" He told me I was an idiot and hung up on me..
What am I not getting? Any input?
Thanks
