Hello Max🙂 Greetings from Denmark. Thank You very much for Your fine videos of which the ones about Your sailboat and especially the Haswing protruar electric motor has inspired us to get one for our sailboat too. We chose the Protruar 5.0 version (160 lbs) as our boat weighs 1800 kg. It works fine, we have similar results as Yours, making about 4 knots using 40 to 45 Amps or just over 1 kWh when motoring in calm conditions and 3 knots with 6 mps wind and sea against the bow, using about 45 Amps. The motor is rated to max 100 Amps or 2500 Watts but such load makes little sense as the speed gain is small, probably not even a full knot for using so much battery power! Please feel free to ask for more info, I'd love to share our experiences on these fine motors. I hope You are well and healthy🙂 Best regards, Kim
*I bought this model for my 14 ft Jon boat. **enjoyable.fishing** recommend love it!!! It pushes my boat with ease ( 2 men 220 each). I would highly recommend this to anyone.*
Ich bin noch immer sehr zufrieden und habe noch keine technischen Probleme mit dem Motor gehabt. Der Antrieb selbst (BL-Motor) wird ja von vielen Herstellern verwendet, lediglich der Zusammenbau mit Schaft und Regelelektronik unterscheidet sich optisch - und natürlich der Preis. Da findest von 700,- bis über 2000,- Euro für die selbe Technik alles im Netz. Kaufentscheidung muss jeder für sich selbst treffen. LG, Max.
Hi Max, Thanks for your comprehensive video. I'm looking to buy a Protruar 3.0 also. What I find interesting is that the max amp capacity of the motor is 60 amps, but you only get about 44. Is there an explanation for this? Thanks.
I guess thats because of the load. The heavier the load the more amps it will pull. So i think if you try to pull againt a rope. It should pull more power. At max throthle the motor is limited by the rpm. Not power
The measurements on my boat are not laboratory conditions! Voltage drops in the cables, internal resistance of older batteries, etc. can be the reason for the deviations from the manufacturer's specifications. Nevertheless, the engine still convinces me today. -Max-
its sort of like on a generator when they say 2000w max, 1800w running, it's marketing and it's sort of a truthful lie. Electric motors like this are designed to draw a specific amount of current and spin a specific diameter and pitch prop at a certain RPM in water at a given voltage, in this case around about 44amps at 24v. As you increase the load, the motor will draw more and more current even over 60amps, that is why it is important to use a fuse with trolling motors like this, if you don't, it's possible to burn out the motor. One example of something that increases load is weeds/seaweed, if you cut through some really thick stuff, you'll see the current go up on the motor. Too thick and the shear pin is supposed to break but if it doesn't and it keeps drawing higher current, then that's why you need to fuse the connection.
Other replies kind of cover it but I’ll add my 2c. As stated it likely reaches it’s max RPM with the 45A. If you threw a storm anchor or a bucket tied to the boat in the water it would consume more. Or…if you had higher pitch propeller you could go faster with same motor rpm but higher load (potentially too high = overheating and damage). Troll8ng motors have low pitch props to provide a lot of thrust at lower speeds and to protect the motors from being over taxed. In practive in many applications they could benefit from higher pitch prop tomget the full potential in use. This is especially true for easily pushed light boats.

Prima! Fast perfekt bestätigt: Doppelte Geschwindigkeit -> vierfache Leistung.

anyone know what swiveling/spinning boom is called? I've never seen a mainsail furled up on a boom like that. It's neat!
Danke
wie viel lbs hat der motor
hier ein Auszug aus den offiziellen technischen Daten:
Motorleistung (dauer/max): 1320W ~ 1440W
Leistung/Schub (kp/W): bis 49,9 kp Schub (110 lbs)
Spannung (dauer/max): 55A ~ 60A
Betriebsspannung: 24V DC
Spannungsfenster: 17V - 26V
Hallo Max,
bist Du mit dem Motor noch zufrieden?
Danke/Gruß
Peter

Protruar 3.0 110lbs ~45A
Protruar 3.0 130lbs ~ 60A
This is 110lbs!

Why are these so loud.
