Dredging Question Motor?

16 posts in this topic

I'm looking at buying a custom dredge, it has a honda 9hp with a Keene 3x4 450gpm pump coupled to a tri haul jet. My question is that it seems under powered? but I have never seen or heard of a tri haul jet. The claims are that it is equivalent to a typical 6 dredge with 16hp and a normal jet set up. Please help .

Dahlke makes the Tri-Jet log. I don't have any experience with them but The claims is they are more efficient than a standard side induction jet.

Last weekend I fired up my new Keene six inch dredge for the first time, it has two Keene P180 pumps rated at 250 GPM and Honda GX200 engines rated at 6 HP.

I ended up running at 3/4 throttle and had plenty of suction and the box cleaned out fast.

I would imagine with the more efficient tri-jet you will be just fine. Might need to run it at full throttle but that Honda will handle it.

Good Luck............IMG_1637.thumb.JPG.698c21626222d63b5bb6c9ffc84c2174.JPG

Yes it has the triple sluice. Looks to be the same as yours with a different motor - jet setup. 

I like the way the single is set up. May be harder to pack in but it looks really clean without all the extra hoes and what not.

I would be curious how that set up does in rough water. I would think with the motor up high it would be less stable???

How was cleaning out the triple stage? Looks like a lain.

I knew a couple before that had a Dalke Dredge with the two get.  It was a 5" with if I remember a 8hp.  They said it had a lot of suction and I know they didn't run it that hard at all.

I have a 6" like sjmpainter with plent of power.  I had guys tell me before that a 6" needed 9hp motors but currently I don't see the benefits with cost and weight.

They would be nice in deeper water with a longer hose.

It's a depth thing. For less than 10 feet you are probably fine. Deep dredging is where extra power requirements kick in.

Is the jet and engine the only "custom" item?

Yes, a very experienced gentle man just told me it would not work😧 but the person that built it is 70yrs old and claims he knows it will work wonderfully, claims it would be almost equal to 16hp! I wish I could test it

      Remember when you used to be able to dredge in California.....
      First photo is beginning of last dredge I built.  Second is dredge in operation.
      Notice my huge jet... all of about 10 inches long. Got tired of wearing the metal ones out.

      Thought this might be a good add. Now I can have a hot sandwich wile I'm dredging.

      Edit: this topic was split from this thread on modifying a pump intake.
      Steve,
      I believe that "plastic cuff" you are referring too on the P-180 dictates the pressure of the pump?
      I had one P-180 setup that I had a pressure gauge on the outlet side of the pump. (4" dredge)
      New, I think it was about 38 lbs. of pressure.  I filed off the "stop ring" on the plastic inlet fitting and tapped it in towards the impellor until I felt it start to drag.  I now had 54 lbs. of pressure at the outlet.

      I bought a new dredge last fall and I'm fixing it up for cold weather dredging. Added drain plugs, TinyTac, new matting float plugs, some paint and hot water.
      Now I'm working on the hoses. I am going to add CamLoc fittings for the pump intake and pressure sides.
      My question is what to do with the jetlog inductor ports?????
      Anyone have an idea that worked well for them?

      Steve, you stated you installed drain plugs on your pumps. I picked up some 1/4 inch drain cox's to install on my pumps. Any words of wisdom before I go drill my pumps? Little nervous about this.

      Went to the claim at Canyon Creek last week to see how things look. I was surprised to see some creek open.
      Being I have a bad case of spring fever I have decided on spring dredging this year so thanks for the post.
      Anyone know where to get a water heater for the dredge? Not looking to set up a heated wet suit just want a bucket of hot water to warm the hands in.
