To trim or not to trim?

[jetskiking]

I was going over my winter project in my head and got to thinking about trim. I keep getting conflicting info. I read that some people dont use it to backy and some do. I was talking to someone that can and they said they dont use it to backy but use it for set up wakes. I set up my boat for cruiser wakes at Lanier and surf type riding which is mostly the riding I do so set up wakes are not crucial but I do use them sometimes. After watching my buddy struggle with flipping a down nozzle and throw money at it to still not get it working yet (you know who you are:sneaky: ) and the expense of a bolt on I,m wondering are they worth it? I'm refoaming and doing a scupper so now would be the time to install a tube for a trim cable. Any feedback?

I've always hated the way it makes the ski handle. the nozzle always flops around. I've seen skis flipped without them, so that's the way I've been practicing. Maybe the new expensive trims work better, but I havent got to try one yet. You could always install the tube and just cap it until you use it.

Yeh, I pretty much talked myself into installing the tube anyway just still on the fence with the trim. Beginning to think its more balls than anything

good thread.. i'm going through this same debate right now.

i have the trim nozzle.. i have the tube for the cable running through my hull..

why won't i just put it together? i dont know.

my thoughts are pretty similar to superramjet's.. but i'd like to hear more .02...

Do you have an aftermarket trim or a down nozzle flipped? My buddy is having problems with the bracket on a flipped down nozzle. He had one made at a machine shop but it seams flimsy. One part of the gracket is really thin so it will clear and looks like it would break under the stress of the pump. Is there an easy fix we are missing? If I had some pics I would post them. If we could figure it out I would be more tempted to run it on my ski. I have been waiting to see if he got it working but its getting about go time for me.

im gonna run the tube when i do mine this winter.

might as well.

i have seen the SCATS trim and idk what to think of it. if i were going to get something pricey then thats a diff story.

im just gonna leave it stock for now

i have 2 trims sitting in my garage, but i havent installed them. i used to run trim but broke the cable and took it off. i can do EVERY SINGLE trick i could do with trim without it!!!! i want to install it and see if i can go bigger but that will be done later. i havent tried any backys, but as soon as i get my lehr engine i will be trying them allllll day long.

I bought a protec drop nozzle setup for 150 a few years ago and just ran the cable furrel through one of the bolt holes for the reduction nozzle, cross drilled a bolt and used 2 nuts to jam together. After I installed it The washers on the bolt hit the hull so I bent the bolt down to make room instead of removing it to redrill a new hole. It is a KISS setup. I like having it but don't know if .... Well yea I would install it again it is super easy to do and if nothing else you can use it to spray other riders as they pass. It works good for making a taller setup wake. I use it to sink the ski in the water faster when going into a tail stand. It is great when you are doing fountians. I havn't tried a backflip so I have no idea how well it would work there but with the trim pulled and peg the throtle when at idle and the ski jumps out of the water and you land back SO I am sure it would come in handy It has alot of uses but the new setups have a ton more throw and I think I might have to go that way on my next ski. Here is a few pictures on is of how much throw it has and the other is my bolt idea

i like that bolt setup, thats good thinking!

I am a trim junkie :biggthumpup: Modified protec system :Banane01: But I am flatwater guy

Just fitted the new Wammer one - loads of travel - here's some pics from the Wammer site. It has a ton of travel and super smooth ball raced! - very nicely made peice of kit..

Think there's a video of Jason Stoyer using it on this link:

My c.a.t.s. was like $106 to do, $75 for the raider nozzle off ebay, and the rest for the cable from Terrycable. For $100, it's well worth it. (a local bike shop gave me the lever for free, and my ski already had the tube.

My cable attachment is very similar to speedfreak's (either I got the idea from him or him from me, whoever did it first probably posted a pic on pwctoday).

I still need to mod it a little for more throw, but it works nice.

That is what I'm putting in my roundie I'm building up. I figure now is the time to do it right.:beerchug:

good thread i agree! i wanted the start a thread about trim systems and was wondering if they do flop around or what not?!?!?
ill probably make my own in my sn but dont know where to start. maybe just modify my nozzle with a couple brackets, return sping, etc..?? i can make anything as long i can see some pics :biggthumpup:
i already ride in the surf and can get 8-10ft jumps with it want to already come around. i think if i get a lil more brap, finish my footholds and make some trim ill be on my way to backflips :cheer:
lets see some pics of everyones trim and post some pros/cons, and is it all worth having seeing that i ride i the surf already?

i am totally flatwater (hopefully some ocean time at march tx motosurf)- put complete pro-tec trim system in grinded on for more throw- i had some bolts on trim nozzle stop plate come loose once, but now are red loctited and i have no complaints or performance issues to bitch of at all- at first i did not think i used it, but now if i ride another ski without it i am constantly reaching for lever that is not there- guess i use it more than i actually think about it- i only use it for jumping or backflip attempts that i can recall

 

[Glory_Freestyle]

the trim system may be more flatwater than surf related.. i dont think its really necessary in the surf..

I agree totally, for the few backy's I've done in surf, I didn't use the trim at all.

For boat wakes, I'd say it's almost a necessity unless you're trying off of something 5ft or more because the wakes aren't steep like a wave is.


Here's some pics of my C.A.T.S.

You don't need a return spring the thrust of the nozzle keeps it down which also doesn't alow it to flop. In fact the force of the water comming out won't let you pull the lever at WOT.

I was wanting more throw out of mine but I see how they do it now by looking at the wammer setup. The attachment point at the nozzle is closer to the pivot of the nozzle. They use a type of snatch block to get more power out of it.

What a good idea.. And for the record I was reading up on the CATS system which Darin was building when I installed mine. So the ideas are not mine I just bent the bolt when the washers hit the hull...

they are at lanier:biggrin:

I meant "normal" boat wakes. Lanier is a whole different story. Like I said, for bigger boat wakes, you probably don't need trim.

I redid quite a few things on my trim today, looks like 20 degrees now. Before, I probably had 19, wow, huge improvement! lol

Actually, my problem was my steering cable end was binding after about 15 degrees, plus I wasn't getting full throw even with the ski out of the water, add in cable stretch and I might have been getting 10 degrees.

With moving the attachment point down, and angling my pivot bolt to prevent the binding, I am expecting to get the full 20 degrees which isn't too bad for a C.A.T.S. system.

The nozzle tends to slap my bond line and the lever sometimes slaps my fingers.......I was planning on installing a spring. You are right about the thrust.......it just doesn't work when your flying through the air.
