Outboard question

[Seastoke]

Is the bottom end cooled by the impeller or by just being in cold water

 

[Rappey]

The impellor pumps straight up to the bottom of the engine block so it's cooled by being in cold water

 

[Mr Googler]

Electric outboard conversion is going to go super well I think ??

Have you thought about gearing Or are you just going to plop a washing machine motor in place of the engine

That’s a good question...the lower leg is full of oil, that must help...

 

[Seastoke]

There is no gearing on on the top end , and after your bellows debacle, I don’t think you can comment.

Electric motor running at 20,000rpm.
Propeller gearing at 2.5:1
What could possibly go wrong??

We are using Tesla technology .

dont even bother trying to bring sense to this ?

 

[Seastoke]

Corona , is that a dc or ac motor and what voltage.

You wont get far from dock on an extention lead you know.

 

[ChromeDome]

Solar is the new black. Distinctive design too

Your clothes must be shredded after one wash!

We are looking

to harness lightening using LIPC TECHNOLIGY, and storing in to lithium batteries mounted under the pontoons .

Well I was warned!?

My apologies for the late response BB.

I’ve had a few difficulties with my internet.
Discovered a small ‘leak’ from one of my internet ports, so had to shut the router down.
Just like that big gas company which lies to the east of Europe.………

The Motor can be ac or dc……but I wouldn’t recommend using a long shore-power cable for the ac version!?

Voltage is around 375v……you’re unlikely to get a battery at Halfords.

I don’t know what your plan is………but a 75kw battery might be a ‘tad heavy for a small tender?

I’m sure Bouba could answer your questions a lot better. It’s the same stuff that’s in his car.
He may even have a ‘spare’ motor and battery lying around somewhere??

 

[Seastoke]

It will be an AC motor driven the batteries will be in a grp box moulded not the central seat , charging can be an issue but I may fit a dc to dc charger socket at the stern of the boat .

Gearcase and gear oil is kept cooled by being in the water.
what rpm is your motor putting into the top of the drive shaft ?

Well thanks for reply , that is why I need to know what a say 3.5 hp revs puts out at top end , as I might have to offset motor to give the right speed , ps it will be a dc motor brushless. 24volt

 

[Rappey]

I need to know what a say 3.5 hp revs puts out at top end

The 2 stroke 3.5 revs to 4200 - 5300 rpm

 

[snowbird30ds]

Most small outboards rev to around 5000rpm.

ROLLUP! ROLLUP!
I'm holding beer bets 50:1 that Seacock's lower gearbox fizzes away leaving just the gears and plastic propeller within a fortnight.
