My Discovery 3 v6 was 188 bhp and pulled fine but had 100nm less torque than the 2 litre VW.

The place I bought mine from cant get enough of them most sell before they hit the forecourt.

However I can confirm they drive well, have loads of grunt, tow well and the MPG is an improvement over my allroad

I've got a Transporter with the 180bi-turbo & the 7 speed dsg. I can't say that it sets me on fire, but it does the job & it's loaded up its nuts, I get 35mpg + knocking about & 38 on the motorway which I can't complain about.


.....sh1t happens.......

All of which is fascinating I'm sure, but none of these is a spark-ignited diesel outboard.

I'm intrigued as to whether being spark ignited makes this an Otto-cycle engine or something halfway between a true Diesel and an Otto. It'd be interesting to know what sort of compression ratio it's using as well — presumably higher than the petrol version, but not that high, or there'd be no need for a spark plug. The block might not be able to handle typical diesel engine compression either.

The current 175hp OptiMax is 2.5L and 195kg, whereas this is 3.0L and 236kg.

From this document [http://www.mercuryracing.com/wp-cont...nce-Chart.pdf] that went with it:

Quote:
This engine does not meet EPA, C-ARB, or CE exhaust emissions requirements... It does not conform to the exhaust and noise emissions requirements of the Recreational Craft Directive.
So it's not for the likes of most of us anyway. I know the RCD doesn't apply to racing, but what about CE? Does that limit it to military applications only?

I guess technically it's not a diesel engine at all ,I thought the definition of a diesel engine was a compression ignition engine.
An interesting concept but it seems little benefit to use spark plugs with an engine running diesel fuel I'd assume the lower compression ratio means that it doesn't take full advantage of the fuels extra energy potential over petrol
The only benefit I can see is the possible ability to run any available fuel
If they just want a diesel outboard why not go down the route of a high output small traditional compression ignition diesel block
There must be good reasoning behind going this route but I'd be interested in why

Doubtful. Modern Diesel injector pumps rely on the lubricative properties of diesel. They no likey petrol.

A small high output Diesel engine would need to be turbocharged - which presents problems of packaging and heat dispersion under the cowling.

Didn't Barrus knock up a Mariner that was a military burn almost any fuel job? Think it was a small motor though.

I'd expect a lighter block will not be far off so as others have said its just a matter off time, wonder if they'll supercharge rather than turbo charge?

Not realy a problem with a water cooled turbo you can almost touch the case without getting burned
