Diesel outboards and jetboat engines coming

[gonzo]

A pull start diesel with a decompressor is possible. The problem is that they are big and heavy.

Looks normal to me.

gonzo,
Yep. And it's about time - cleaning up the engines and increasing fuel efficiency isn't rocket science.

Really-- perhaps you could tell us how you can do that then?

I've specced Yanmar diesel outboards on work boats for fish farms, etc, but recently have been told by the Yanmar dealers here that the diesel outboards are no longer really availble. I believe they were only ever batch built in response to someone like the Australian Government ordering a load at a time.

Although they found favour in some markets, they were horrendously expensive and heavy with only two (low-ish) power options.

I think the advent of the larger 4 stroke petrol OB's killed them off for most uses.

Here's an interesting looking engine development from Australia. It was brought to my attention on another subject thread dealing with diesel/electric technology

JetPac has two jet propelled diesel outboards, 150 and 200 HP (A different kind)
Bulky but efficient, allow for outstanding maneouvrability and reduced consumption. CE marked.
I have personally had nice feedbacks from professional users.

Diesel outboards have been availble for awhile from a Chinese Manufacture Zhongshen, they have since stoped production and now a marine Company in India who had some samples from them has improved and started to remake them and offer the 10Hp Diesel outboards, these use standard Engines that are Availble from China and are very economically priced, starting at around 900USD, they also have a power pole version of the outboards,
see http://www.goodsdirect.net/dieseloutboards.htm all these types engines are in productions,
