I just checked the site & yes, the 200 hp diesel is intercooled. The enine cooling system is close loop with a watercooled radiator.


A quick google search for 'sword marine jetpac' produced this article;

I wonder what speeds you could get comparatively...
I drove those units a few years ago when they were under development by the inventor Bill Lawson, before he sold to Sword. They worked well, did not wander at slow speeds like previous water jets, and they performed better than the equivalent powered stern drive. You can't believe how quiet they are.

but you are not in the market for a jet drive - the USP is not that its a big engine - its that you can have features/benefits normally only available on an inboard without loosing the space or cutting holes in the hull etc.

it does address many of the disadvantages of an inboard instalation.

Interesting, thanx for that.

Don't suppose you've driven one in winter/ice conditions and can comment
whether it could be configured for use in winter w ice .e. reinforced impellers or the like? Just curious...

I tested the engines in Florida where the only ice is was in our drinks! Better contact the factory for that kind of info.

Since you are one of the few people to have actually seen one of these in the flesh do you think there is any justification in the concerns people expressed about the forces acting on the transom? i.e. is it suited to wave jumping?

Unless you're clean out of the water, I'm not sure the loads will be so high since the unit has it's own buoyancy.

Although lots of pics on here and in magazines have folk showing off with their boats out of the water, if you drive properly you may find you rarely get into that situation.

I don't understand the oo-ing and ahh-ing that folk do when they see a boat out of the water, and therefore out of control, with it's bow 3mtrs into the air. Kinda like doing handbrake turns in yer car.

Perhaps I'm too old to know.

JW - has no one told you the higher you can get your boat out the water the bigger everyone will believe your manhood is . Perhaps its the kind of midlife crisis that boyracers have... ...they love putting stereos and big amps on their boats too!

Each to their own I suppose - although I guess your point is if you are going to jump waves buy a big petrol outboard. If you want a diesel jet - you are probably not wanting to jump waves anyway.
