diesel outboards

[Pericles]

Bollard pull for 200 hp diesel is 1200+ lbs. 2.8 litre inline 4 cylinder diesel. This engine is turbo charged and intercooled, it has a modified water jacketed stainless steel exhaust manifold, a closed loop cooling system with a stainless steel/cupro nickel heat exchanger and intercooler, and develops 200 horsepower at 3,600 rpm.

Pericles I tried to open the brochure but got a lock up--ctrl+alt+delete was my only way out.

I guess I don't have the connection. I did however down load enough to see a RIB flying over a wave. I suppose they must be good then.

On the above photo there was a bar across the photograph that seemed to be covering an intake grill cut into the boat. I could'nt see too clearly for this strange style of photography,-- that was right where I wanted to look.

I assume therefore that a grill has to be cut, but im not sure.

Frosty,

No holes cut in bottom of boat. The unit is self contained and the fibreglass shell has positive flotation and supports half the weight of the unit when immersed. Guillermo is the chap to ask, as his company sells and services Jet Pacs in Europe I believe.

Granted the unit is a little expensive in Europe, say $30K to $36K compared with Mydauphin's $21K in Florida, but so are 4 stroke outboards. Bombing around in a petrol fueled go fast boat that needs big tanks for fuel at $8 per gallon does not work for me.

A chap at http://www.coastalrides.co.uk/new_engines.htm suggested an alternative. A pair of new Vetus VH480, four cylinder 80 hp diesels adapted to fit Volvo Penta Duoprop stern drives £4950 each. The stern drives are £2500 each. Now that's £14K ($28K) plus fitting, however the diesels will run on a mix of 80% veggie oil and 20% petrodiesel, because there are no turbos and they have mechanical injection. We are going to lose access to red diesel at 56 pence ($1-12) per litre in 13 months and, courtsey of the EU, we will have to pay DERV prices. Wholesale veggie oil is 40 pence per litre!!!

So, 160 hp (with two engines) on Duoprops are about the same thrust as a 200 hp Jet Pac, which it would be unwise to run on veggie oil, thus leaving only one other question. How important is the shallow draft and the safety aspect of water jet propulsion to the prospective purchaser?

Like all things nautical, compromise is always present. We have come far from diesel outboards.

If was looking at such an animal. I would buy a large Jet Ski type water jet and hookup a small diesel like 60 hp and retro fit into fiberglass sell. Probably $3000 used or $5000 new. Not 200hp, but do I want all that weight in a glorified dingy?

Hi guys this may be your answer http://www.megoutboard.com/ 300hp retro fit coming first then new

[oldcroc]

Just a bit of a bump really, any words of wisdom on these motors anyone seen or got any more info? thanks

Hi guys,
I'm an avid follower, posting for the first time. Tell me off if necessary .

How about this as a power head onto an outboard leg. It's an 18hp diesel, maybe someone could give further info as to what kind of leg to use with regards to prop and gearbox ratio's. Note the engine is vertical shaft.

Looking forward to your replies.

I seem to recall there being an ~18 hp Yanmar outboard a while back, but it was pretty rare (if in fact it was real). Could be a similar powerhead.

The trouble with the one you found, hawkerdonkey, is that at 190 lbs it's a brutally heavy beast compared to gas outboards that size. You'd be looking at taking a bracket, leg, etc. from a gas outboard of two or three times your rated power, maybe more, in order to handle the size of the thing.

...a shame really, it looks tidy .

Thanks,
