C.A.T.S. - Cheap Arse Trim System - post yours!

Is this cable you Guys are getting from Terry Cable the same as the Xmetal one?
We made a CATS using the xmetal cable and now need a cheap replacement but don't want to change the rest of the setup.

If anyone was interested I just utilized a SBN44 stock throttle drum on my BS CATS setup. just have to order a longer superjet throttle cable from Terry Cable. Thought it would be cool to use a normal throttle lever for trim

I bought a cable from terry cable and It lasted about 3 rides. Wasnt very happy considering it costs about 45 dollars.

I'm getting ready to modify my stock 1994 SuperJet reduction nozzle. In an effort to keep the stock reduction nozzle made for this boat, I'm going to weld bosses on the sides to mount the 62T trim ring.

I've read that the holes on the sides should be 3/4" back off the exit of the nozzle and dead center top to bottom. Is that correct?

Why not just get a 62T nozzle...?

 

[Allistah]

From the research that I've done, the insides of the nozzles are different from a SuperJet versus the Raider. People are saying if you can stay with the original nozzle, thats the way to go so you don't change the dynamic of the water flow through the nozzle. Not sure if thats fact or not, but I can get the bosses welded on pretty easy so it will be cheaper as well to go this route. ..and I'll be 100% certain that it will be the same.

 

[Allistah]

I don't have the two to compare side by side so I don't know. I just read that there are differences on the inside because one was designed for the larger machine while the SuperJet is of course smaller. Thats not the case? i wish I had the two so I could look at them side by side and determine that myself..

 

[Allistah]

Ah ok. Good to know. Thanks for the clarification. Unless I can get the right reduction nozzle for ~$40 shipped, I'll just weld the bosses on what I have I guess.

 

[Allistah]

Do you happen to know how far back from the exit side of the nozzle to the center of the holes for the trim ring are? I've heard people say they move them back further than stock but I'm not sure if this is a good idea for a drop nozzle for racing.

Mike Coe from Sacramento - Factory X Racing was his sponsor I think? if that's the same guy I've rode with him and practiced in the Sac River with him back in the day a few times.

So your recommendation would be to mount the ring deeper on the reduction nozzle which would help prevent water from escaping on the sides? Maybe when I get the bosses welded on, I'll do it so I can drill/tap a couple of different positions to see which way feels the best.

Here's where my cable attachment is threaded into the trim ring. You can see where I used to have it.


There is a hole drilled in the stud and the nuts/washers hold it.



Due to the Raider nozzle having trim, they had the cable attached in the center on top instead of lower like on a SJ nozzle, so you have to lower the pivot point some to clear the cooling fitting boss on the pump.



This how close the steering cable is to the cooling boss.



I have the cable ferrule bolted into the pump, and a short bolt in the front sections so I am not losing any strength anywhere.



20 degrees, I did notch the rear of the bondline as the stream would be blocked just barely if I didn't.







Free left side brake lever from a local bike shop. I cut off the thumb shifter obviously



20 degrees. To get more, I'd have to get new bosses welded on to mount the pivot bolts further back so the ring is on a smaller diameter section of the nozzle.[/

Awesome write up but the pictures don't show up

Heres mine:

X2 Trim nozzle
SkatTrak Cable
UMI Lever
Scrap Metal

The x2 nozzle configuration does that only work for kawis? Because in the picture it looks flipped from a superjet. The steering cable and trim cable that is.

Would this trim ring work on a 95 superjet? It seems like that rubber seal around the ring would help direct flow at full trim. Instead of losing water pressure and thrust out the side

This is a great thread. A day after reading it I've already ordered all my C.A.T.S. components. The only thing I'm struggling with is how to get the cable through the hull. I seem to have an area roughly 18 inches long in my hull (from engine compartment to pump area) that I can't understand how I would get a pvc pipe through. If anyone can get me pictures or insight on getting the cable in place, I think I will be all set.

Thanks!

I used a long drill bit they sell at home depot for running cable thru walls. Its like 40 dollars for the bit and i only ran the cable housing thru it. If you want to use pvc i have seen some guys cut sharp notches in a piece of copper pipe and use ot to cut thru the foam after drilling a hole with a hole saw.
