    Need for speed and high volume output

    Getting to larger creek and stream placer sites in North Carolina have just gotten a lot easier. I bought a jet ski that functioned mechanically well and mounted it somewhat creatively into my 12' Sears john boat. The advantages are great... no prop to foul or break and it operates in less than 16" of water. There's no need to drag a dredge unit with me... the output from the john boat jet nozzle when hooked up to the sluice jet will suck the fillings out of your mouth at 20 feet.

    Did I mention that this rig has approximately 50hp available to the jet output. Advantage... I can run this engine at low speed and still outperform most suction dredges with no problem. Let's start to think outside of the box and get somewhat creative.

    The cost. $300 for the boat and trailer; $35 for title/tags, $100 for the jetski, $80 for metal fabrication and misc parts. If the weather is bad, I'll still be able to go fishing. WIN, WIN.

    May the yellow stuff blind your sluice, not you judgement.

    Great job with that. I thought about that idea before but didn't know how much pressure those jet drive pumps put out. What size suction hose are you using?

    Be aware that some states limit the motor size on the dredges permit wise. Doug.

    Great job, I am quite impressed.
    I have been contemplating on using a jet ski in ecuador to access some remote locations, but I was to slow to add it to my dredge as well.
    How is the fuel consumption, its not a big issue at .30 a litre just wondering
    thanks for the input

    NC CLAYMAKER, YOU ARE A FREAKIN' GENIOUS!

    A FEW MORE MODIFICATIONS LIKE A GLASS BOTTOM, AND MOUNTING THE SLUCE BOX UNDER THE BOAT AND A FEW REMOTE CONTROLS ON THE SUCTION END SO YOU CAN OPERATE THE DREDGE FROM THE DRIVER'S SEAT.
