Bayliner Conversion

[tai626]

I think It is easier for you to transitioning from the electric bike to boat. I come from model airplane so it will take me a while to get things figured out in real world.

The thing that worry me the most is the system reliability. I am having redundancy in almost every components. I will be starting a thread to document the project and hopefully getting help along the way.

Please post the progress of your project.

eastgem replied to me about running the asynchronous motor at 60V and they said , no problem. found a video of the motor on youtube, it looks like a pretty good app

ive been busy working on the boat, yanked the inboard motor, removed the leg/outdrive and 40 gallon fuel tank. i think i took about 800lbs off it. then i busted 4- 8 foot long x 1inch thick x 27 inch high stringers through the transom into a bulk head 5 feet inside the engine bay which left me with a 3foot fiberglassed positive floatation pod

going in the water today





the boats sitting 4 inches too high in the water with all the weight loss and extra flotation but thats ok because now im cutting the roof in half and stretching it for solar panels and cutting the upper transom/flooring and pulling it back. i want to get all the topside work done then pull it out in the summer to put the shaft in and spray foam the pod and shape it once i know the waterline



starting to look at solar mppt
i want to run 17s/60v, pack voltage ranges from 71v to 51v

victron

and fangpuson

are made in the same factory but only go upto 48v

go to amazon and they have these 48v/60v/72v mmpt

why doesnt Victron do 72v?

for others thinking of doing a cabin cruiser, i follow this guys channel and his 30ft Tolleycraft

i went looking for 72v/dc diesel generators for charging

found a 12kw and 16kw might weigh about 100lbs?

lots of chinese gas

72v/dc-2.5kw gas, 50lbs and 60decibel

u seen dis?

ya i saw that, i put a wanted add on craigslist for broken 30 to 50hp outboards
hoping to find a 40hp merc bigfoot (big prop and 2to1 gearing) to convert with a 10kw water cooled motor

i got a isuzu 3kc1 30hp diesel with drive from a 35ft sailboat for free, the catch was i had to get it out of the keel without damaging anything. its sitting in my backyard waiting for a rebuild gasket set, had to take it out in pieces

solar sucks, atleast up here it does, if i got 4 panels, its only 750 watts for part of the day and wont cut it. 50 years of solar and all theyve accomplished is 22% after all the billions spent on research??? and victron cant do 72V????

so little diesel inboard to get me where i have to go at hull speed and fish all day on electric outboard was where my thinking was heading

its cold and wet up here most of the year, you need heat, batteries and solar wont do it, back to diesel cabin heaters, or small diesel motors with cooling jackets so you can heat the cabin with hot water from the motor, trying to find the right mix

that little diesel generator puts out alot of power

Solar does suck, especially above the 49th parallel. [url=https://unboundsolar.com/solar-informat ... urs-us-map]If you lived in Cali/NV/TX the Gulf to Fla you'd be good to go!

Diesel Electrics the way to go then you dont have to worry about the sun or clouds or rain or shadows.
I don't mind using fossil fuels for what your doing, its the only way to go if you can find good deals on engines because you can ALWAYS find great deals on boats. I bought mine from Texas and brought it up into Canada.
I would have personally just rebuilt a more powerful (then stock) outboard engine and call it a day, maybe look at different props to see what improvements you get as those boat repair shops would be the place to go.

Your boat looks a tad small if you ask me, but if you got a good deal on it then its better then nothing.

Lots of good info on design, but the motor weight is a good point to.

Adding length changes things up, plus need naval architect. Better to just buy a longer boat.

Weight of propulsion system is very important!

it got me to thinking about replacing the alternator with a 72v 2000??? watt alternator for charging the batteries

Happy New Year!

I am following your conversion closely.

it will be spring til i do much more to it

im looking for a controller that can be interchangeable between ebikes and the boat, waterproof, can handle 10kw max but usually only about 700 watts, can do 3000 watt continuous

a Nucular 12f fits the bill, i think you can also charge the batteries from a solar panel through it, i need to read up on that part of it.

https://nucular.tech/

if victron cant do 72v, i think the nucular can take 48v from solar and boost it up
