Have you considered using a twin armed tiller on the Kort Nozzle shafts? With one arm connected to the servo, using the heavier rods you already discussed, and the second arm connected to the other tiller assembly, it would really firm up your steering

I have, but I'll need to find one that's not 180/straight. I need a V, acute angle version so my nozzles maximize their turning ability.

You can always make your own. A shaft collar like you'd get from Dubro/Sullivan etc, plus some thin metal, drill your holes, cut the arm out, and solder them on.

I was thinking the same thing. Some 1/16th aluminum would work fine for the arms. Just make sure it's 6061 or 7075 as most other types are too soft to hold up. Other types of metal might not work due to soldering/welding issues

I found Shaft Seals that will fit my Kort Nozzle shafts(5mm). Then I ordered some aluminum tubing for them to fit in, and cut it down to 1/2" tall. I'm going to drill a hole large enough to set the aluminum tubes at height, and then peanut butter epoxy them into place. I can use Teflon washers to shim them perfectly.

You'd have to glue the aluminum on, which I wouldn't personally trust. I've used both brass and stainless, depending on what material the shaft collar is made of, and solder to suit. Stainless is of course preferred, but requires a much higher temp to get the silver solder to flow (and silver solder ain't cheap!)

Water Cannon progress.


Taped off the holes before filling with epoxy.


Added some fiber as filler, so it's not all glass.



1/4" Plywood to reinforce the area.


Removed masking tape and drilled out the holes.


Test fit the Livewell pickup for the Water Cannon.

I started with a 1" hole, but had to elongate it for the elbow to fit down under.

And it fits! I had to use a 1/2" NPT tap on the bottom side of the flange to open the threads up for the elbow.

I like it.

I have multiple updates, but the site seems to have disabled my ability to upload attachments(photos).

I will continue to update the Shelley Foss Facebook group and post to my instagram account @birdizzo

Thank you for ALL of your tedious attention to the details of your build along with your meticulous photos of each stage of the process! Great work.

I don't have any real updates at the moment. I posted my lastest work to Instagram and Facebook. The props are turning and so are the Kort Nozzles. I took everything out of the boat to install the LARGE water pump and hull fittings.

My next step is to start sealing up the outside of the hull. I plan to do two layers of fiber glass over the hull.
