How long do y'all think until a 200hp electric outboard with solar panels integrated into cowling show up on boats

Never.

The amount of battery power needed to move a boat, must be like 5x to 10x more than a motor vehicle.

Like with dirtbikes and snowbikes. A dirtbike with an electric motor, a la Alta Motors Redshift EX, might have a range of say 50 miles.

If a snowbike kit were installed, the same bike might go 10 miles in the snow-tops.

Talk about "Range Anxiety", the boat would sink full of batteries just to go 5-10 miles out.

solar panels on the cowling would be decorative, unless it's a .0200 hp engine.

The electric outboard is pretty easy. The weight- and cost-efficient power supply is not.

the Sun only hits the earth with so much energy. You can't fight physics.

Electric cars get the equivalent of 50+MPG, and are just barely feasible. Boats get anywhere from .5 to maybe 2MPG on average.
Until electric motor/battery technology starts to approach something 100 times better than what is on the market now, electric boats won't be a thing, beyond some novelty small/slow flat water cruisers.

Electric outboards are here, but the limitation is battery technology, and marginal improvements to existing batteries are not going to help; we need a battery yet invented that weighs one tenth or less.

Solar power - aquawatt electric yachts, electric boats, electric boat motors, solarpowered vessels, solarpowered yachts - Green Marine TechnologiesREACH / TRAVEL TIME

With optimum sunlight can drive six hours continuously at 5.5 knots, goes to 4 knots, this is 10 hours. At night can be driven with 4 knots 4 hours with 5 knotes or comparable 6 hours. Unlimited 2.5 knots - in sunshine 2.

In other words, practically useless for what most people consider to be "boating". If you live on a really sunny inland lake, maybe it would have some upside. Many people boat in rivers and currents that would make that thing die literally standing in place.

A 'real' boat powered only by the sun? Not practical with current photovoltaic and battery tech.
That said, electric boats are certainly feasible, a hotel I went to was using an Hinkley electric runabout as a tender/water taxi type deal. It looked cool as hell and while it only had something (I think) like a 40mi range, it would get them through a normal day of use, then plug-in charge over night.

It'll be a long time before battery technology is up to speed for an offshore center console boat...... The again I heard Vela Boatworks will have it soon...

They have them all over northern europe. Certain lakes won't allow IC engines.


It would make a lot of sense for lakes or bass fishing crowd as they have to plug their boats in the night before anyway to charge their trolling motors...... It's coming, just hasn't been adopted as much in the US.

Electric is good for slow speeds for short distances. If you are going to do solar + electric, why not use wind powered?

Torqeedo has been making electric outboards for some time. Have had mine over 7 years.--still running well. But the big ones are very expensive--as are the Li batteries. Think over 31K for the basic battery, to give a 80 hp outboard a range of 18 miles at 18 knots....They make electric. inboards up to 160 hp each.

Practically a range to get offshore--probably a long way off.
