epropulsion Navy 6.o Evo. is what they call the 2021 version of their
most powerful electric outboard. A few notes.
Looked thru the in-the-water Manual, which is not quite up to date*.
Perhaps there is another coming. I want a hard copy, not available.
Down loading 55 single sheet pages doesn't do it for me. I want an
actual Manual. Assume one comes with the motor in the box!
*New downloadable Manual talks about coolant for the shaft and
gear oil -- believe these are no longer necessary.
There is a lot of careful stuff to learn about the electrics. If learning
curves are bell-shaped, mine has a crack in it.
The Ariel motorwell clamp is about 17-18" from the water surface.
The 30" Navy 6.0L Evo when hung on the clamp-board will put the
top of the 13"D prop 5-6" under, which is about right for the motor
to run and prop not to cavitate. But the Ariel squats, crew aboard or
cruising trim will alter things. I installed a jackplate that can
electrically lower the motor -- but I'm going to remove it, added
weight. And it's a thing.
Here's a new rub: When we first were asking what the OB motor
weight was it was around 65lbs for the Navy 6.0, or so I thought.
Now it turns out the weight of the motor alone, not including the
tiller or steering module is 81 pounds. I've triple checked it! That's
more than I can move around..
This means, of course, once the 6.0 Evo is installed it's not going
to move -- except to tilt.
Three E40 batteries, the minimum to run the motor, weigh 186lbs..and
it would be smart to have 4 bats hooked into the motor, that's 247lbs
Cases are 16.5 x 8.2 x 15.4. (Can be stacked on any side.. the face
side with controls is the 16.5 x 8.2.) Never planned for any battery
stowage to be 15.4 plus wires tall.
NO, the batteries cannot be STACKED, because heat generated wld
be a problem. They can only take 122 degrees F. Which is ridiculous.
3249 for the motor. But the Evo tiller is about 300 extra, and is not
included in the whole weight of the motor
so is the charger, cables, and batteries at $1000 each. Not to mention
the solar panels. etc. It's almost rediculus the weight & expense to be
fossil free.
Going 'global' certainly expensive. There's still Top and Bottom paint
to green-up, no solvents aboard ship. We have natural varnish in
LeTonkinois, but I'm going to paint most of it over in grey & white.
Because the luscious ease of Tonk is erased by the varnish having no
lasting power in the California sun. I can't deal with that.
APPLES VS ORANGES
We have a lot more electric oranges than gas apples, in comparison.
So we have a lot more weight aboard, and a lot more money, and a
lot more to get comfortable with. Getting rid of the petroleum presence
that's the beauty. No longer having that 110lb Yamaha 8-4stroke is
more about the smell than climate change, that IS what it is about.
And the weight. But look at this 81+lb Navy Evo!! What? 25lbs of
copper windings in that sausage? A lot to chew. If we weren't
fossilizing the planet, that loud smoky monster looking purdy good..
AND light-weight lithium bats in heavy stainless steel cases. Bit Nutz.
If I cld find the space for 4 E40 batteries, that if stacked on edge the
4 of them is like having a 250lb football crewman aboard in weight
and mass. And I just heard, the motors won't arrive until August.
Hope the once young and restless university student engineers have
all their ducks in order. Have all my OOPS to deal with, don't want
epropulsion OOPSES all asudden coagulating on a strange lee shore..
OK, you nonagenarians ATTEN HUT!
ePropulsion Hype admits that the Navy 6.0 (the first motor the Hong
Kong University student engineers developed -- but now totally different)
is the backbone of their company -- NOW it's more looking like an
over-engineered Frankenstein monster. In no way does it compare
with the 4-stroke 8HP gas motor I impetuously sold away on craigslist.
I may be forced back into the dark ages of carbon footprints.
