New DIESEL outboard.

you can still buy a diesel with a rack?
( ok pull start 1 cylinder )

 

I looked for an example at the biggest Yanmar Leisure Engine today if it still has a rack . . . .

Yanmar Leisure Engines ---> Page 3 ---> 6LY3-ETP (353 kW / 480 mhp)

PDF: Specification Datasheet: 6LY3-ETP --> Page 1, right bottom corner, the engine right side view drawing, is there a rack on the backside of the fuel pump . . ? ?

For a better view . . .

PDF: Operation Manual Engine: 6LY3-ETP --> PDF page no. 49 / 90 (real bottom page no. 41), Figure 7, is the stop lever 1 operating a rack there . . ? ?

 

I have had an electronic 470 hp mack run away when it blew a turbo seal and ran on its own oil until the sump was empty. It was off the tacho till it stopped.i have also had a gm 12 71 run over 3000 rpm when it used to suck oil out of the air compressor on a drill rig. Gm's will also run away if overfilled with oil as well. But this is not a common event and there is always a reason for it.

 

sure has and its tier 2 compliant, amazing

 

Unless the power-to-weight ratio can be brought into the same general vicinity, I can't see diesel outboards really having that much appeal. Outboards generally power small to medium planing boats, where engine weight is important, and sitting at the extreme end of the boat, more important still. Commercial operators doing big hours certainly would be interested, especially as the fuel savings could more quickly offset higher initial price. But if there is going to be a big weight handicap, the gap won't be wide enough, and particularly so for recreational users.

 

agreed
I dont see them competing with SI outboards, just supplying a diesel alternative when you must have diesel and maybe some low speed grunt for commercial work but..
how about turbo supercharged 2 stroke diesel outboard....

 

Not sure where I saw it (on this site, possibly ?) but Mercury are allegedly developing a two-stroke diesel outboard in the 200 hp range that has similar weight to petrol engines, but uses spark ignition, maybe with a lower compression ratio than a "normal" diesel, don't know much about it though.

 

all they did was mod an engine to allow the military to use diesel in it.
Doesnt meet any regulations, its way down on power as you could imagine
the BRP can use Jet a1 quite ok but if you put diesel in it you create massive carbon deposits so not practical
Either way the military get down to 2 fuels which was the reason for both.

 

So it runs on jet fuel (kero ?) but not satisfactorily on diesel ?

 

OMC have almost always had kero versions somewhere in the range/world
DFI on a 2 stroke made it a no brainer, I'm sure Merc can as well.

dunno why they advertise
you cant buy one or use it in the USA or Europe

 

It is all academic if you can't buy it, for sure. Unless there is a eco-friendly version in the wings.

 

Have you seen the demo the Navy Seals do with the BRP 55? ( military version)
they hide underwater with a rib and the engine during a on water show then inflate it, 3 pulls the evi is running
The engine has a valve on the crankcase they open and when you pull it it allows the water to come out, close it and pull and your away
How to go ashore from a sub is my guess as to what thats used for

 

Too James Bond for me. I doubt any of these things are optimized for either affordability to buy, or run, so won't be readily adaptable or available to recreational users.
