Reply With QuoteHow much for 200HP?
Was doing some research on diesel outboards (thinking about buying a Cruise Craft Outsider 595) and stumbled across the Daytona Marine Propulsion 'Jetpac'. No, I am in no way affiliated with them!I just love innovative things like this...

A self contained jet unit that bolts staight onto the transom.
Specs here on their EU distributors page:

Initial purchase price would be higher, but it would be cheaper to own and maintain due to advantages like:
* no transmission
* no exhaust risers
* no hydraulics for steering, tilt or trim
* engine be serviced by any mechanic
* closed loop fresh water cooling
* no impellers to replace
* no engine flushing
Yes, they do weigh more than an equivilent outboard, but they are self buoyant, so there is no weight hanging off the transom when they are on the water. I do question how the transom would hold up to trailering with that amount of weight hanging of it though...would probably need a support of some sort like you would use for an outboard anyway.
Yes, they stick out the back a bit, but when you take into account how much an outboard engine case, prop and pod stick out, there's nothing in it.
Check out their YouTube channel

The 24min promo video and the one of a unit fitted to a Zodiak SRO 700 with 6 bloke, gear and 3400lb of sandbags is impressive.
Contacted them and they said there is a guy at Southport with two of them. I have sent him an e-mail to see if I can go and have a look.
They are about to release a 3.0L TDi 225HP model as well. There is also a 275 and 300HP unleaded model which uses the GM 5.7L V8 (this is on the big white boat in the promo video).

How much for 200HP?
What could go wrong.......................
Awaiting a reply from DMP. I'll let you know as soon as I get one...they have been quick to reply to any queries I have had.
Two words that come to mind.....Innovative.......fugly
As far as I know the original guys are out of business and let patents in aus expire a couple of years ago. I am not sure about the European end of the business
Their initial market was for the millitary with the 2 fuel policy. Avgas and diesel and no petrol so outboards were on way out. Diesel outboards basically can't comply with pollution laws in developed countries and so the idea was to use marine steyre inboards as they complied and were light and compact.
Sword marine was the original name of the guys who lodged patents.
There was to be both a jetpac version and also a prop version. Great ability in the future to have a 2 speed gearbox in them to get on the plane but have very effecient cruise and not have a prop that was a compromise for both.
Great idea to be able to change out a unit fast in a millitary environment and to get diesel into pleasurecraft designed for outboards. there was going to be quite a market in Japan , pacific islands and Australian charters or large powercats which is why I first looked.
I hope someone makes them in bulk as they are a good idea on the right hull as you can fit a lot of HP low down with service access and still have large hold and fishboxes in the boat.
If you find out any info I'd love to hear about em again. .If I can find them I have some proposed prices from years ago
Edit - Just looked at the link- maybe they are being built again?
Yeah mate. Bought out by DMP.
They are definitely in production again.
If you like diesel and outboards here is another option -

My only concern is how the fibreglass pod would hold up in the FNQ chop?

interesting, point one says they use automotive engines not marine for reliability. Why have we bothered to marinise engines then????? I may be missing something, wouldn't be the first time lol.
Remember to always log on before heading offshore.
I can now foresee myself chopping off the nose of a kawa 300x pwc and strapping to the back of a 4m tinny! Could get up nice and shallow in the creeks an get there fast too
The idea is great if you are happy with the jet drive and having a large pod on the back ( which would increase LOA and planning ability with buoyant pod) and as the jet is driven off a belt and closed loop cooling then engine options are unlimited. Hmmm 1000hp 20BT or TT LS1 on the back of a 18fter CC.
More readily available parts and you don't need to go to a boat mechanic to get it serviced.
Auto engines are typically lighter too when compared to their marine counterparts. Look at the Volvo/Mercruiser V6 - just an old cast iron Buick donk. Why they haven't moved to the alloy V6 that is in the current Commodore or the Aurion is beyond me.
