Electric powered boats are not the future. They are a very healthy present, and have had a very long and beautiful past.

Not sure what you mean?? obviously diesel electric has been around since the 30's. It is also by far the best and only way to move large mass. But a retrofit electric motors and controllers that will replace a big block is only now becoming a reality. One or two boat companies that are making battery powered electric boats are not a healthy present.they are slow and more like sailboats. The 2 including the one you link are playing on the retro look to sell the boat with a Eco friendly plus selling point. The Edison With Twin transwarp 9 motors($2275 each plus controller,charger and battery's) one or two in series would be a viable transplant for a bayliner. but I doubt it could push a modified V hull with a single prop to the speeds that have been achieved with combustion engines.
"But then maybe it could"

specs on the transwarp 9

9.25” diameter, series wound DC motor
Weight, approx. 160 pounds
32.3 HP (72 Volts, 335 Amps)*
70 Ft. pounds torque*
5,500 RPM's

Developed for

EMIS and direct drive applications


Advanced timing – factory set for CCWDE (CWDE available)

1.125” keyed CE shaft (matches 00-08219 DE)

Commutators key locked onto the shaft
High quality, large style brushes, factory preseated over 90%
Exceeds Class “H” insulation – temperature snap switch + brush wear indicator
Turbo 400, 32 tooth splined shaft





Slip yoke assembly and tail shaft housing also available as options


The future is that all boats will be powered by electric, not at a present day with a handful of boats that no one has ever heard of.


The future is that my Minx will have a an electric/hybrid
But I'm skeptical at spending $10,000 + dollars and I don't know if it would actually work.
But this seems to be the motor that I would start with:shades:


(transwarp 11 secs)


11.45” diameter, series wound DC motor


Weight, approx. 229 pounds

43.7 HP (72 Volts, 453 Amps)*
135 Ft. pounds torque*
5,500 RPM's
Developed for direct drive applications – double DE bearings!
Advanced timing – factory set for CCWDE (CWDE available)
1.125” keyed CE shaft (matches 00-08311 DE)
8 CE mounting holes (for alternator, air conditioner, etc.)
Commutators key locked onto the shaft
High quality, large style brushes, factory preseated over 90%
Exceeds Class “H” insulation – temperature snap switch + brush wear indicator
Turbo 400, 32 tooth splined shaft





Slip yoke assembly and tail shaft housing also available as options

As battery and capacitor technology advances It will become more prevalent.
The brushless AC motors show the most promise as far as power density is concerned.

Formula one and the Le-Mans series have adopted this technology.
Capacitor devlopement will most certainly bring the weight down as well!

Bring it on.
