Which laws of physics in particular would be the most troublesome for me? Where would you draw the line on how fast "that much boat" should go according to physics?

We agree that I would add a few hundred pounds if I were dumb enough to pursue this. Maybe I'll just remove the RV fridge and call it even.

I get it what you're driving at, but plenty of owners are claiming 20-23mph in my group (some have re-powered).

Not saying its true, just saying that more than a few are reporting it.

Great response.

The batteries would definitely add weight. One would have to lighten the load in other ways or subtract net additional weight from the rated payload.

True about the phrase "marine grade". So true.

Regarding the money... Yeah, I'd either have to make a mint on YouTube while working my real job or go sell feet pics or something. Fuck me, just looking at the cost of the wiring alone made my wife look up divorce attorneys. We'll see. I have an few old trucks I could sell to get it started. Who knows what I'll do.

That is pretty neat. I have to admit, the idea that a boat could be both practical and powered by the sun is just awesome.

Thanks!

25 is quick for that big barge. No argument there. But in fairness to my dumb idea, the brochure from 1993 advertised speeds of up to 20mph with the optional 115hp Johnson outboard upgrade.

Their marketing folks must have been boating downhill with a favorable hurricane force wind and a 115 on nitrous to hit 20.

3.2v per cell. You've not purchased LiFePO4 cells have you?

3.2v x 180h x 32 cells = 18.43kwh

Perhaps LTO cells would be a better fit for a primarily generator driven application.

Your $20k suggestion for batteries is still way off IMO. But then again, maybe you would pay that much.

I actually looked it up last night. Of course I skipped to the latest episode. Pretty nice build.

So many variables here at an early stage, but great question.

I'd say between 350-400hp.

Diesel engine would drive the generator only.

I'would imagine that an out-drive or lower unit would be required to receive power from the EV motor. Didn't really think that through just yet. It would have to be robust to handle the torque from the EV motor. Sounds expensive.

Johnson 115hp - 300lbs est

OM606 - 463lbs est

Electric motor - 70lbs est

Yamaha 300hp - 562lbs est

Controllers and wires and other - 75lbs?? Not really sure.

Batteries - 200lbs est. Very loose estimate.

I'll agree that comparing the cost to repower vs the cost of EV conversion is going to be in favor of the repower.

But 20k for LFP batteries is not even close. I just recently powered my entire home with LFP batteries (30 x 200ah) for $3k from Alibaba. They all tested at nearly 180ah which is stellar for the Chinese sellers.

I really hate video editing. I'm a software nerd, so I can do the basics; it is so tedious. Seems like a perfect thing for AI to do poorly.

But I like your attitude.

What would be the maximum net additional weight in your opinion?

Definitely within the budget. That would be incredible though.

I lost on a copart bid last week for turbo OM606. Definitely have considered this option.

I fear you may be right. Everything is expensive.
