Torque Prop?

Recommended Posts

MadMan

I have noticed people referring to a prop with a lower pitch as a torque prop. Why are they called this?

Not really a correct term imho but it is more of a way to think of it......like a lower gear produces more torque in a truck.

That's what I was thinking, it mimics the additional torque multiplication a higher (numerically) gear ratio in a trucks axle.

Only reason people call it that is cuz that's what Malibu named it on the option sheet. So it's just marketing.

It can be very deceiving cuz Malibu has changed the "torque prop" many times. It started as the ACME 2315 in 2013. Then in 2014-2015 it changed to the ACME 2419. Now this year it is the ACME 2249.

I prefer when people just state what prop they're talking about.

I didn't realize "torque Prop" was a Malibu marketing term, I thought it was just internet slang.

And I thought it was just boat slang. People used to talk about "torque props" and "speed props" back in the '60s.

But since my "speed prop" might be your "torque prop," I agree with IXFE. Just refer to the diameter, pitch, and cup. I hate that Acme uses cryptic numbers.

haha but who wants to walk around saying 14.5x14x.105?

I'd rather just say 1235 :)

But ya I see where they could develop a reference system that made sense

I prefer the actual technical details. But then again, I wouldn't refer to a color as "teal", I would just give the wavelength of 490 nanometers.

Using part numbers 2315, 2247, etc is not that big of a deal. It would be different if we were referencing 100's of props, but really there is less than 20 that are relevant on the newer boats.

And for those among us who can't memorize those dozen or so props:
