The below information was supplied by my motor vendor for my 2021 Marshall Sanderling (2200 lb. Cape Cod Cat sailboat). It's not quite what you're looking for but I think it'll put you in the

I am looking to repower a 22ft Norwegian wooden boat with an electric motor. The boat weighs in the 2500-3000 lb range. The 5kW thunderstruck kit would probably do, but their advice is to get a 10kW

S/V Retreat Time is a sail cat, intended purpose is coastal cruising, 1st season Bahamas second season Maine, third season sea of Cortez. No particular reason for the 18KW systems, they are robust

Thank you, Dan I'll revert in a day. I have the same issue, with channelling to the berth. I do not use engine when out on the sea, but winds can get so bad, so it is more comfortable to do motoring,

I did a lot of number crunching and estimating or the performance of my electric drive before I built it. That was mostly based on performance reports from other similar boats and some other

Hi, Dan The props are probably the real key here...And, actually, the use of the cat.If you have a cat, then consider retractable engines in the middle.Stupid to have a big fast cat, with fixed props

Hi, John Be careful of doing so. You may end up being fried instantly ! You'll get toasted.Ask a VERY good marine engineer electrician to do the switch installation job for you, buddy.The connections

One reason you might choose this particular kit is to get the water-cooled motor. I think if you want to be able to motor continuously at speed you really need more robust cooling than the air

Is it a sail cat or just engine powered, John ?? I'm a bit confused, why you need 2x18KW for a cat

Greetings my fellow Electrosailors, the day has come after nearly a year of waiting for chips, motors, pumps, fans and now the final details need to be identified, she is getting repowered with

Correction - That should be 1, 2, Both selector switch..

That model is 12V. I have two 100Ah 12V AGM batteries with On-Off-Both selector. Had plans to go to Torqeedo Cruise 2.0 someday if the boat satisfied my needs, but have not make the move yet. I could

Thanks Walter, Is that a 12,24, 0r 36v. motor? And what do you have for batteries? Glenn -------------------------------------------------- Sent: Monday, January 24, 2022 12:45 PM To:

I use a Minn-Kota Endura Max with standard prop on my 19' O'Day Mariner. The trolling motor is six years old and has PWM. It's remarkable how efficient it is at low speeds. I separated the control

Dan, That answer is no as far as "trolling motors". Everything with 5/2 speeds is Pot/Resistance controlled. Motors sold as "variable" speed are usually PWM. and more expensive of course. Since the

Interesting. I wonder if it's a moot point and basically anything you would get today is going to be PWM? Dan Pfeiffer

OK all you tech. guys (I'm NOT). Has anyone done a test with controlled inputs and readings for the benefit of PWM (pulse width modulation) trolling motors? All I know is that they run much longer

Does not look good , with all corrosion

Thunderstruck ev has plenty of free info.
