No not mine. Are you looking for the early Precision aluminum pontoon dredges or the later poly pontoon type?

Most of the Precision dredges were custom made but they all had the square powder coated frames, some of the later ones had stainless square tubing for the frames. "Later" ones being the 2010 models when Jim started making them again for a while.

Very innovative dredges for their time. Most of the "modern" features on dredges today were first made available by Precision. Jim didn't create the design but he did perfect it. :thumbsup:

Im looking for the early aluminum float version.
I have a dredge in my back yard that I think may be a Precision and I'm trying to ID it. I could just be made of some precision parts

I think all the Precision dredges were just put together with precision parts. :laughing7:

Seriously though I'm not sure if Jim ever made two alike. By the time he figured out what you wanted it for he would have planned to create a dredge made for your purpose. If Hoser John is around I'm sure he would know.

That being said a lot of one off dredges from the time were made with precision parts. Is it just the pump that says Precision? Other signs to look for are the remnants of a light blue sticker on the box, square powder coated steel tubing for the frame. Of course the box would typically be longer than what most dredges are built with today.

I'm certainly not a Precision expert but a picture might help? :thumbsup:

Hoser John is an encyclopedia of dredging, havent seen him online is years.

My dredge has a Precision pump with a Briggs Vanguard 23hp. It also what looks like a prototype couple jet. The interesting part is the box. It is a delta or alluvial design with an over/under box. Looks totally custom but well made.
I will mow the blackberries off it and take some pics

OK, I hacked back the blackberries and pulled the old Precision out of the weeds. I stacked everything together about how it would look when assembled. The dredge is 6' wide and 14' long not counting the aft flotation.

Wow! That’s a gold getting machine!! Kind of a shame she’s sitting in the weeds. I suppose we all end up resting in the weeds eventually.

I'm pretty sure all Precision dredges were "one of a kind"
I posted the pics on FB and most people never heard of Precision
