Continuing my search for a donor boat for an electric project and wondered if anybody had any ideas what make and model this cabin cruiser might be? Advertised as a 24ft.
24ft cabin cruiser - any ideas of maker and model?

Gosh - no idea what it is, but are you sure it's worth putting the effort into?

Not at all sure! But as long as it floats I could use it as test bed for electric outboard conversion. I know I could use any old dinghy for that but if I could find something that might work longer term too that would be a bonus.
The reason I was hoping somebody might be able to identify it was if I could find pictures of a model in good nick to help evaluate if it might be worth the effort.

So are you building the out board.

Plan is to dismantle an old outboard, remove the engine and connect an electric motor to shaft. I have also been considering same exercise with an inboard shaft but outboard might be easier in the first instance.

Fun project, though you don't really need a boat to try it out, a wheelie bin would do

Are you thinking ac motor though inverter speed controller , or dc and what voltage.what hp outboard you thinking.

Well that’s 13 hp, so it’s either 10 or 15 hp.

The boat looks very home made. I doubt it has a brand name and model, and I doubt it has any sister ships.

You are looking at around 200 amp.

doesn't get worse than that.

Suggest buying a cheap running outboard boat. Something you can sell on when you become more ambitious, as you invariably will. What you are looking at is a money pit which will distract you and your funds away from your electric project.

You only have to look along the hull and see she's had a hard life and having stood as she is - probably not cared for latterly.
If she was a 'Freebie - collect and take away' then maybe ... but I suspect she will be a heavy boat and need significant work to be suitable as a test platform.
With regard to using a wet fuel outboard as base to convert to electric ... I would think - the electric power needed to run a conventional leg would be seriously limiting. Look at a commercial E outboard and you see lightweight drive and leg ... lightweight prop and fittings ... no need for gearbox as the E motor runs either way depending on which way power is applied.
That means a serious Brushless motor ... serious ampage ESC ..... assuming you use the existing gearbox .. then it will really need grunt !
I use Brushless motors in my models and they range from CD player sized up to powerful 60xx size. Those 60xx size are swinging 18 inch props etc and pulling over 70A ..... that's without all the extra your outboard leg will have .....
Imagine the battery bank you are going to need to get any useful run-time ??
I do not wish to 'rain on the idea' but I think the proposed boat and idea may be far more than you imagine.

Others have done the outboard conversion. PBO did an article a few years back about one, person was somewhere in Scotland and recently I saw a picture, etc of one on faceache as I call it !

That boat looks like you'd be doing them a favour taking it away but it will cost you a fortune and still have no value.
You really need a shaft drive boat as it would be so much easier to convert, leccy outboards run a bigger prop slower for efficiency and the gear case saps a lot of power.
Outboard props are usually sized for higher rpm/speed use.

I think ,it would be easier to stick a ,say 10kw motor direct to a shaft and prop , like the long tailed boat in Asia.

Fine ... but practicality of such as Run Time ? Weight ? Motor Power required ?
If it was so viable - why are not more conversions seen ?
I can remember seeing an article where someone converted a Strimmer to power a dinghy ... great ... but a good strimmer can cost more than an Electric Outboard !
