Having the exhaust hang over the back of the boat helps get the COG back far enough for the pumps to work properly. Having it cut across the transom at an angle also helps get teh wieght distribution left to righ balanced as well. This is important, if the weight is to onbe side or the other the baot will want to turn that way. These boats need the COG much further back than a prop boat. Here's a pick of my Swashdrive set up. It is balanced at 29% COG and if I pull the boat to one side oir the other it will tip back up and sit on the delta pad.

I also posted a pic of Craig's (designer of the Swashdrive) cockpit on his personal Swashdrive, I pretty much copied his layout.

My friend is waiting on one of the Jettec units to put into his Davette, we played with the MHZ & gave up on that unit, it's got so many flaws it wasn't worth the hassle. The swashdrive hull is 34" long. I thought the Davette was 36" long.

Here's my build thread on ModelJetBoat

There is also a thread on there of the Davette build I did for my friend along with a lot of other projects.

It looks like it has two halves, but the bolts are cast into the case. It is basically the same as their last unit, but with the HK style trimable nozzle on it.

I like the chrome, I painted the side of my jetsprint with chrome, but made the mistake of clearcoating overtop which took the polished effect away. Looking good.

Which pump are you putting in? One of Adam's Jettec pumps? We're waiting on one of them to ship out. Apparently it should ship this week. It will be good to test my Swashdrive hull against my friend's Dana Davette Jetsprint side by side with the same pump in.

the pump is a jettec pump adam sent it thursday nice bloke to deal with .dana what is the cog on this davette sprint just to be sure

phillio35

heres the pump

I have my engine 10 1/2" from the transom and it works great there . But the jettec pump looks longer then my mhz pump so that might be alittle tight for you .

If its not too much trouble , is there any chance I could get a couple of dimensions from you?
I've emailed Jettec and had no responce as yet. I'm getting close to completing a new jet sprint hull and would like to make sure I've allowed enough room for the Jettec pump.

Here's the dimensions I'm after:
A - overall height
B - intake overall length
C - start of intake to transom face
D - overall width - lug to lug


Thanks in advance,
Jay

yes i will give you the sizes when the pump is here that picture was when adam sent to me 3 days ago ready for sending

With the Jettec pump, most of it hangs out the back of the boat. The hull ends between the uptake and where the rear cone bolts onto the uptake. You use a rubber boot to seal between the jet pump and the hull.

Really like the look of this built!!!!
Hendix do you make that pipe?

hi all got pump today from jettec cost me another 130 £ customs nice so the unit cost me all in 590£ cheap not.anyway besides all that the pump is a nice bit of kit on adams part from
jettec .i started today as well from the instructions adam sent with the pump told me to put stator where two halfs join to put level with the transum because theres no gasket like
with the swashdrive pump but that would mean another 3 quarters of inch towards the front of the boat but i didnt go with that so did it like it should be like on the swashdrive hull same as diko,s from rcu but theres no gasket so had to fill with silicon dont like the look of it mind thats the only way could of done it so heres some pics.

link to first test had prob with coupler but ok

Adam has the backing plates if you want one you could ask him for one. You can make the rubber gasket from a bicycle inner tube.
