Trolling motor heating is related to current draw, which is related to load. For a well-designed motor, if you operate it below its maximum rated current, you should't have any heating problems.If you

Glenn - Awesome, do you have any data on the current vs. speed.? What material was used to print the prop?

Ken - Any suggestions on drilling the shaft hole for the prop?? I used my drill press yesterday to drill my 15x7 Master Screw prop.? I let the prop self-center on a surface square to the drill bit,

Günter - I second the quiet time on the water.? My family has a very nice fishing boat with a 250HP outboard, minimum planing speed is 21 MPH and you cannot hear yourself think.? I have owned

Nice, thanks for the info on your retrofit.? There is just not a lot of options for the big slow propeller.? The lower half of an outboard can be purchased very cheaply for some of the Chinese

There's a couple of good free prop size calculators. I would Google them. You can then look at the torque curve for the motor you're getting with respect to the RPMs I'm sure there are people who know

I feel an urge to jump in on this discussion but lack the EE knowledge and experience. Allow me as briefly as possible to say what I've done and invite anyone who is barking up the same tree to

For these little electric off the shelf trolling motors, To fit the prop to your boat, you just have to do some "sea trials". Buy a range of props between 4" pitch and 7 with different diameters"

Some one said 10x4 or 4x10??Also heard If not matched right it will?burnup the motor

Any guess what size prop to use with old 24v 4hp mini Kota ?ThxDon’t think it’s actually 4 hp but that’s what it says

Hi Keith (I answered right after your questions, but the post was going somehow into the drain. So I'll start anew.) At now I don't know anything about really achievable cruising speed

Do you have a thrust bearing? Seems like something is wrong, based on your power useage.

Use heat sensor gun . It points out your heat problems immediately. ?Detects hidden corrosion on any contact. A must for electric boat drive ? ?Terminalift LLC9444 Mission Park PlaceSantee, CA

What is the (temperature) rating of the motor windings? A class F motor (winding) is rated at 155C. "overheating" is a relative term - a motor can be operating perfectly fine but the casing is also at

I'm no expert but seems to me too much torque from the prop running this motor direct with no gear reduction. 80 degree Celsius is 176 degrees Fahrenheit. You could cook dinner off the motor, probably

Hi, I'm using a direct-drive BLDC motor and was a trouble with motor and Kelly controller overheating in the past. Problem was in high RPM motor that never can reach its optimal RPM with high torque

I would first use a thermal camera on the motor and controller while at temperature. A lose connection and/or a poorly crimped cable will introduce a significant amount of heat. If the cables are

Hi I've recently finished my conversion of a 29 Roberts 4.5 ton yacht. 1200 watt panels 270 Ah batteries at 48 volt 15s3p Batrium BMS My usage stats are Rpm.? ? Amp.? Knots 530.? ? ?57 500.? ?

I have a 20' aluminum pontoon powered by a Minn-Kota eDrive (2hp) 48 volt four 12 vdc lead acid batteries. I haven't measured the speed, but at one-half throttle on the speed control, the motor draws

Totally agree re power vs speed. Our 20ft solar side paddle wheel punt uses just 300 watts at our 4 knots / 7km/hr cruise. We only have 60Ah of 48V battery capacity, but this would keep us going for
