Mild WDK ROK Build

I remember when the Hookers first came out, It was around 1776.............. LOL, More like 1476! That said, everyone was screaming get a 9/15...... They were running the old DASA cast cylinders, stroked motors........ I called Dave told him my spec. 84mm Big Bore 61X. His response "10/16". He was spot on. I later in life tried a 9/15, It bored holes in the water. Later had one pitched to 9.5/15.5, I had dropped back to an 82mm ported 61X. The 10/16 worked just fine with it, just tried to tweak it a bit with the custom pitch. If you have bone stock cylinders and pipe, 9/15. Any other mods, 10/16

1776 is not a real year that didn't exixt.

Paul said 9/15 or 10/16. I went with 10/16 after a second opinion. I have an LPW 735 Shredder top end and a b pipe along with a zeel, and a Solas 144 12v. I think 10/16 will be perfect.

You will need to see how quickly it jumps on the pipe and check peak rpm. The 10-16 can easily be pitched down, that’s all IMPROS did to make the 9-15.

10/16 should be the ticket. You can always add shims behind the impeller to loosen it up a little or bore your outlet nozzle. I added 2 mm in Shims behind my impeller and it loosened tye pump up just enough where it can quickly come on the pipe but not slip. A friend had a shredder 62t setup probably same as yours with 38s but he had a 9/15 with a bored nozzle maybe 2mm oversized. It was wayyy tooo loose in my opinion. It didn't cavitate or anything but I could feel the engine wanting more. But he could send it as well as I've seen with just a basic tried and true 701 setup..

Got the ski back from paint, FINALLY. Went with white gel in the end. It went on pretty badly because it was sprayed while it was so hot out, but whatever. Spent the evening sanding and buffing. You can see the matte finish on the side in the above picture. We did a test patch on the nose.



Then after a few hours of learning to sand and buff, here's the side. The bond rail will be turfed and the top peely part will be covered by the hood, so I'm not worried for now. I can always go back and perfect that next winter. But check out that finish!

220 > 400 > 600 > 1000 > 2000 > Buff > Wax.

Excited to get her back together. Gonna gel the bilge once I've made all my mods and mounts for my tank.
