Not trying to talk you into outboards, but I'll take and post some pics of how I recessed mine into the sheer panels to make the bracket/nacelle set up much more compact.

And if I could add to Phill's excellent post there - Mas, it is also easier to tack with an outboard than a diesel

Outboards are also lighter, free space inside the boat (you need an ice maker), and can be used to steer better in small spaces. Easy to service and require far less services than diesels. Fishing line and the likes is easy to get off the prop also.

Thanks for all the comment and interest, so now, is it my turn to give you something in return? - - My Genset has arrived, so compact, and so beautifully set up... I heap praises on Sea Wasp and Wattagan for a fantastic job.... LOOK AT THIS.... I am totally wrapped about a 600 to 700mm cube

No problems and good service from both

And the aft seats and galley is starting to shape up, the space next to the seats will be for a fridge and a freezer of about 170? liters each and then benches with drawers under ("wet galley one side and electric appliances and hotplate the other)....

Alan M.,
The torqeedo is an outboard (electric) and the assembly will be as per species for the maximum size allowed (40hp?) so will be sorted for anything "outboard" - petrol or electric - and someone suggested a diesel outboard... It is just tooo big & heavy so far aft...

I had considered (shaft drive) permanently submerged propeller, as well as folding, and neither, I felt were appropriate... The choice was always electric or petrol outboards...

interesting review of the benefits of an outboard over a conventional engine set up

Hi Boston, Definitely the way to go for light weight multi-hulls (power only - or - auxiliaries for a sail yacht)... applies for both electric & petrol (4 stroke)... and also works for 2 stroke outboards... select whatever for the prefered cruise speed (more power less range)...

ya I always liked your solution with the torquido's
seems that with solar assist you might just have the optimal plan for occasional use
I kinda adopted the torquido idea into my dream boat as well
you had a great suggest
I was just commenting on everyone's take on the peripheral savings of outboard over inboard

I still like Torqeedo, but the battery weight issue and using reverse to stop and be able to accept reduced forward velocity in an adverse headwind situation (my normal response would be - - "Well I am retired, and another day sailing around enjoying a good breeze before coming in to port is neither here nor there..." - - or - - "Oh well I will just head elsewhere, (with the wind), and by then the wind will have eased and no problemo..."

That is one of the issues, - - then add drag from a through hull (even with a folding/feathering prop), - - holes for mechanical stuff (shaft) below the waterline will leak, - - difficulty to fix/repair/change/clear a propeller or shaft or fix a leak, - - absolute pain in the ass to service the engine, - - Similar pain to remove the engine for a major overhaul... - - Almost no case if the option exists for an "outboard" mount...

The genset will be able to be removed relatively easily - unbolt, unplug, disconnect and lift out - almost easier to do the regular service this way...

Hi Masalai,

Bloody hell that's an ugly gen set It looks like a combination between the Lister pump we had on the farm and one of these back packer weed eaters the council use to chop grass with. Oh with an alternator on it.

The radiator goes on the bow, right

Does it work ? You're supposed to start it first to see if it works, then read the manual if something is wrong


He he... why don't they make these gen sets 'outboard' as well. Could repeat all the said pro's again.

I'm surprised Mas, the thing has not delivered one watt of power yet other than gravity and you are already making plans to lift it out ?

Yes, I'm enjoying this

I saw this documentary on crocks in osto%!@*#. The vibration of their skin causes the water to jump off.

I was just wondering if the gen set vibrates like that if the Oram would pick up speed - less wetted area, less drag.

Also wondering if you have to pre-lube it like Frosty's Yanmars. That sounded like a real slep, and all that oil. Probably cheaper to run it 24/7 for a month than to prime it once.

Yes- I'm a 'wonder' person today

Well, it has ceramic cylinders and specially treated bearings and stuff so never needs lubrication, nor cooling (as you will notice no radiator) only a wet exhaust system so the thing does not behave too much like a military jet engine with full afterburners on....I do not know how to get rid of the excess energy and was going to warm the oceans to increase precipitation globally (or for a BIG fee, to not run it and so avoid global warming) - It burns very little fuel using molecular fusion technology...

I have the electricity generation covered - storage is the problem - - cost & weight & reliability & ability to charge with what I have - - (genset for 48VDC nominal @ 6000W and PV panels ~2000W) - - - Seems not many batteries like soooo much juice - I hoped for a 1 hour engine run per day or less... I haven't done all my sums yet.... as to how much electricity things will consume.... but the genset should keep both the Torqeedo's on half to two-thirds throttle almost continuously...
