why do they not make diesel outboard engines! i would have thought some of the new small turbo diesel engines would have been up to the task, do they not rev high enough! too heavy!

Apparently Yanmar make some smaller (up to 40hp!) diesel outboards but they tend to be sold more in 3rd World markets. With the huge jump in common rail / diesel turbo technology I??

yes i too would gladly ditch my 2 stroke for a diesel alternative, i wonder if there is reluctance from the main brands to basically throw away all there years of r&d and head in a new direction, imagine the range you would get out of a couple of 25 litre totes.

Italians make a great diesel outboard called a Rugerinna. I used to have a 40 HP about 20 years ago.

As above, I'd definitely go for a diesel over my 2 stroke Johnson.

If I were you, I would go on a public forum discussing my 'two stroke Johnson'!

I came across a boat about 20 years ago with a diesel outboard (in South Africa). Apparently the manufacturer discontinued these as they were too heavy, amongst a few other issues. Wonder whether we'll be charged WUC's in NZ if diesel outboards were introduced here.

I don't think that way your thinking.
Lol, But anyway nothing wrong with those old 2 strokes! Very reliable motors, never missed a beat, easy to get parts for. My mate has a Suzuki 1991 model I think he said he has a mission trying to get all parts for it.

Honda had a diesel outboard, I saw one on a catamaran about 20 years ago.

I don't think Yanmar make them anymore, Yank EPA would not allow them in the States. Google Yanmar Diesel Outboard, lots of reading in a similar vein

I would throw my hat in the 'power to weight' ring for this one, but as a previous poster mentioned, modern diesel tech is pretty damn good these days. It would be pretty hard to match the light weight / high output of a petrol 2 stroke however, so the diesel would need to be very very efficient to compete as it sure wouldn't be cheaper to buy

What about the best of both worlds! A small two stroke diesel.(apart from the enormous noise of course, but surely that could be managed these days on a small engine)

i am looking for diesel outboards since years and yes yanmar used to make 2 models that are no longer made now. the cilnder head was 1 peace , and the problem with diesel outboard used to always be exessive KG to heavy its whythe yanmar had a zilinderhead and piston sleeve as 1 peace i would guess to save waight but this also brings along problems to repair one day.

Star in China make 2 small ones 10hp and 6 hp I think . Most will not meet the us enviromental standards that why we do not see many larger ones Yanmar no longer make them due to polution requirements

You have to spell out to him what a 'joke' is.

More common in the "Islands" where petrol standards and supply are not what they are in other parts of the world. Some run on Kero, too.

Cannot find that out Sorry . The figures they quote on their web site have errors in them and do not forget that commercial boats get fuel discounts here on petrol .
