Someone replaced their Merc Cruiser engine with a bunch of Tesla batteries in a 2016 Bayliner. CRAZY!

 
Lake Test. No mention of range or top speed though.

EDIT> It's in the comments...30 miles range or an hour of continuous use. Still not there yet. Battery technology needs to improve by leaps and bounds to make this sort of thing viable.

and he spent 20K on the conversion! YIKES.

 
Well @Bruce, you better add an electric boat forum to this site. Too bad he didn't change the prop over to a jet.
 
Too bad he spent all that money on a POS Bayliner.
 
$20k buys a lot of gas...
 
Electric boats are not exactly around the corner just yet, but that will change fast. Some kind of hybrid would make a lot of sense.

Max torque at 0 RPM, anyone?

That much torque down low would rip the arms off a skier behind the boat Lol.
 
It's the silent operation I'm most intrigued about!
 
This is cool. Proof of concept for now of course, but the future will hopefully be electric soon. Imagine twin electric motors mounted to jet drives! Extremely low maintenance, excellent performance, quiet, clean.

Biggest hurdle is better (lighter) battery technology, or better still: some sort of easily refillable energy cell or better yet: on demand micro generation. I hope I live to see the day that small and safe micro-reactors become a possibility.

"Mr. Fusion" may take up too much space on the swim platform though ;)

1.21 gigawatts anyone?

LOL!!!
 
Pretty impressive job! His battery packs (and given the double efficiency of electric motors) gives him the equivalent to about 4 gallons of gas. Definitely don't get far in a boat that never coasts or recharges itself.

Regardless, all of that electricity on board concerns me - imagine a plug blow out filling the bilge with water... ZZZAP!

Guess that means no sub moves.
 
I missed where he mentions the $20k cost, but those 10 57KW Tesla battery packs alone would cost new more than a 242X and maybe a couple of waverunners! I bet the whole rig would be well over $100k new. He obviously must have access to inexpensive used battery packs, controllers and a whole lot of electrical know how.
If those packs are still storing 57KW and given the double efficiency of an electric motors, he has the equivalent of about 40 gallons of "gas" to power that 157HP motor - pretty impressive. (given his comment about range, he's getting nowhere near 57kW out of those packs) He did mention charging via 120VAC at the marina which must take DAYS. Regardless, all of that electricity in a boat concerns me - imagine a plug blow out filling the bilge with water... ZZZAP!
Sorry, I forgot to post the one with the cost. He mentions it in the comments

That is a little ironic. Our boats are not exactly known for their quality of craftsmanship either. That said, I wonder what the payback would actually be on this. I would never do it because of run time and range, but one of the main benefits of the Yamaha is not having to maintain an outdrive. This takes it to another level and means no maintenance on an engine, just the outdrive. I wonder what all modifications he had to make to the outdrive? Seems like a ton of work. I wouldn't have done it, but I suppose someone needed to!
