Cats trim help..

[BBYamaha]

I did a quick search and didnt see what I really am looking for... My questions is with the cats trim I got it looks like it puts my brand new cable in a bind and it wont last long, is there a different screw on part that I can put on the end of my steering cable instead of the screw on piece that doesnt allow alot of throw... Can I use one off a squatter that has trim?

I already attached the nozzle and it fits good and looks like it will be hitting the tray and some trimming my be in order. really please with the amount of throw it has.

Here is what I did, nothing is tightened up in the pictures.

I c now, I am trying to figure out about the steering cable end... I have plenty up and down and it returns nicely but i am worried the up down is going to be to much for the steering cable... you gotta pic of how your steering cable hooks up, is it stock?

O the steering cable my bad. It is hooked up just like stock without issue.

Try flipping the "ball" that attached to the nozzle over. Instead of it being on top, put it on the bottom. That seemed to help for me.

You have to mount the cable lower on the trim ring for more throw and it helps if it can swivel so the cable doesn't flex and possibly break.

The Sea-Doo steering cable end gives about 30-degress of tilt in either direction and it works well with a thread insert to reduce the size.

If you turn the pump assembly upside down you won't have to worry about the steering cable binding on the cooling fitting sticking out.

The raider reduction nozzle needs shims on top of the mounting tabs if mounted in a superjet and a modified 61X aluminum reduction nozzle with tabs welded for the ring will probably perform better.

Here's some pictures of my CATS setup if it will help.

The problem with flipping the ball is when you pull the trim lever it wants to turn the steering nozzle at the same time.

This doesn't happen if you have the steering cable swivel end level with the trim ring pivot point axis.

True. It does turn the nozzle a bit when you pull the trim.

I've just been too lazy to get the swivel end like you have.

Wow you have the cleanest setups I have ever seen. That end is what I was looking for, it supposedly comes stock on 08 superjets but I have access to a seadoo trim setup in the garage I will take a look at. I like that spring, let me guess...McMaster? :arms:

 

[JetManiac]

dammit #.0's is the cleanest!

#.0, Is that a raider reduction nozzle and steering nozzle? Did you add the spot where the Sea Doo cable mounts to the reduction nozzle, or is it on there already? Do you have a build thread for this system? Yours looks pretty fail-safe!

Looking at all the high flying action in some of the pics from Daytona and elsewhere has me chomping at the bit for a little help on the flat water.

Actually that stainless spring came from Randy at Watcon and McMaster sells them also.

The reduction nozzle, steering nozzle and trim ring are from the 1996 Wave Raider 760.

I used some custom made stainless offset bushings to move the trim ring further back and on the steering nozzle to point it downward for more throw upward when engaged.

The Sea-Doo steering cable end was extended longer by just welding the old end to the back side and the steering nozzle pivot point is moved further inward.

BTW thanks for all the complements and if I had to make another system I'd definitely use a modified 61X aluminum reduction nozzle and keep everything else the same.

Also I'm going to make a composite steering nozzle the is about 30mm longer and smaller in diameter soon.

Does changing any of this produce any noticeable changes in thrust? Is that part of your reason for going to the 61X nozzle or the longer and smaller nozzle?

I changed the engine from a 754cc to an 828cc at the same time the trim was installed and it still hooks up very well.

The main reason for using the 61X aluminum stock nozzle is that you don't have to shim the mounting tabs and it's real easy to weld a couple 1/2-inch bar tabs to the sides for the trim ring making it more cost effective.

Also there's an extra hose attachment on the Raider nozzle for the visibility spout which needs to be capped off or removed and I believe the exit diameters are about the same.
