Diesel outboards....

[Franx]

Anyone come across these?

http://www.megoutboard.com/

I notice they don't quote a weight for the engines on there

Any thoughts?

Being too lazy to look it up -

How does the 330Kgs compare to a similar powered Inboard Diesel?

Quite a bit lighter, as if I remember correctly, the twin Yanmar 260 6cyl in one of our boats are around 400ish.

THey don't compare too badly with petrol ones either - perhaps 60kg more than the equivalent 300 petrol or thereabouts....

There's something about an in-line 4 cylinder, 3.0l engine that makes me think that thye've perhaps not quite achieved their mission "To build the most technically advanced outboard in the industry."

That's four big, slappy pistons and a different fuel. Hardly cutting edge!!

[Nasher]

Ah, but 4 big slappy pistons will sound great on a cold crisp morning.

Well I think so anyway

Lovely

It's a 7-9m survey boat I have in mind btw; not a leisure craft... which still doesn't make it any more appealing. The boat doesn't exist yet before you ask. Only a thought at the moment, but it's interesting to see what people think about them ....

It'll be cool if they really do succeed. 2 of them would give 4½ litres of turbo diesel power from a couple of outboards. Much easier than building an inboard installation.

Retro-Fit production will start Nov 2008. Full production will start summer of 2009. I'll keep you in mind. So you still have some time ...

The Mainbrayce Water Taxi in Alderney uses a Mariner diesel outboard. Only one I have come across.

So they've put what sounds like a normal common rail diesel onto a Mercury leg - doesnt sound to out of box to me! would be interesting to see GPH comparisons.

I did say in the original thread, there is no way Brunswick is going to let them cannibalise a Mercury leg and advertise it for sale, perhaps Mercury are just sitting back waiting to see how far they get with development IE... let them waste time and money on this project and then Merc can learn from it and close it down

yanmar used to make diesel outboards, they were very economical but heavy. Not many about, some fish farms used them but they never really took off.
