cruising Amsterdam Canals

 
Edited

dear knowledgeable members,
with pleasure I've been following this forum, with a special interest on electrifying my old steel open boat based in the Amsterdam canals. It's a 5,5m boat, just used to cruise the canals at a modest 5-6km/h (walking speed).?

I've ran into a second hand kit that may work great for me, just thought to reach out before I do something stupid (buy the wrong kit).?
The engine is a?Motenergy ME1003, though not brushless I see it mentioned onThunderstruck and the European version kit-elec-shop, and the controller?Alltrax SPM72400, that I can't find many references of.?

I'm hoping on advice to use these on a a boat, rather then in a cart. No salt water but always somewhat moist enviremont as there will always be (rain) water in the bilge.
I'm quite confident the engine is quite a good fit to my boat.?

The kit that I could but second-hand is including throttle, relais, reverse-relais, motor-frame and 8 Edrive AGM batteries, 6v 330ah. total 3500 euro, the controller and engine are about 1500 together as far as I could find online.?
Would still require some work on cabling and programming thought.?

Any thoughts??

Thanks from Amsterdam,
Elwin
 

I’ve been using Motenergy motors on Sunshine for several years - I have Sevcon controllers. You can reach out to Motenergy for support.?


the motor mount/reduction pulleys supplied by ?works well - mine gave a reduction of 3:1 to get max prop RPM to 800.?

You’d be better off building an LFP battery using Winston (or equivalent) cells if it’s in your budget.?
 

Elwin,

I've been using what is essentially a brushed, series wound golf cart motor on steroids in the Arc for over 12 years and thousands of miles and it's still going strong in the marine environment. While I've spent a lot of that time in fresh water rivers, I've also kept it in a salt water for quite a few years too. I have an Alltrax DCX-500 controller that's I've had a few minor issues with? but found the people at Alltrax very helpful so I would reach out to them for more info.

As for the AGM batteries, lead is dead, imo, unless you can get them thrown in for free I wouldn't bother with them. Don't know if you can get any of the Chinese LiFePo batteries over there but they are very reasonable and I've had good luck so far with several of the cheapest ones I could find. You can't hardly build your own for what they sell them on Amazon here in the states.?

Just to add to the chorus - don’t buy the used AGM batteries. Wait til you can afford LFP.?

As for the brushed motor : I’ve met plenty of folks with older diy electric setups with brushed motors from golf carts and fork lifts that are still going strong years later. I think it’s important to not ever go over the voltage rating of the motor as it will blow it out quickly. So if you can acquire the motor cheaply it’s likely worth a try. Even if your installation are is small I am guessing it’s still smaller than any diesel you remove, and so you have room to try it and later replace it if it doesn’t work out.?

Twenty (20) years later and I’m still driving my boat with the ETEK brush motor I bought new in 2003.? I went thru 3 sets of brushes in that time (and no new sets were available until this past year!).? I cleaned up the armature a bit and have 3 new sets of brushes…sounds about as good that it ever did.

thanks!?

I was not afraid for the 1003 motor, glad to hear the Altrax will probably be fine too.?
The kit of motor and controller seem to be available new for about 1500 euros, battery charger about 800-1000 euros, any idea what I should budget if I would not go with thus used kit? for throttle, reverse, etc...
I'm wondering if 3500 euro ) would be a good price.
LiFePo from will be about 2000 euro for 48v 320ah, incl shipping and import taxes.?

Would be great to have your thoughts, going to see the set tomorrow.

thanks again!

hi all, i just bought the kit as described, got it for 2500 euros. let's see if it has been a good deal...

i hope you can give me some input to get me started.
What is missing is the forward/reverse switch. the Altrax controller needs an external f/r switch.?
I do have a throttle as one, it's called a wigwag throttle with a 3 pin connector, according to thunderstruck is works like this:

"A wigwag style throttle uses a potentiometer with 0-5K ohms resistance in one direction and 5K-10k in the other. It has a 3-wire connection to the controller, and requires controller programming before operation"

Any idea how can I can make this throttle work on the?Alltrax SPM72400? the manual says a 400A current stock/hd switch suffices. the controller has a "ksi", "throttle 1" and "throttle 2" pin to connect?to the throttle.

or maybe better to get an different kind of throttle for this controller??

Thanks
Elwin
