Anyone ever hear of using a WB or WR nozzle on a SJ?

When I bought my ski it had a different venturi/nozzle then the stock SJ. I believe the person I bought it from said it was from a Blaster or Raider but I'm not sure.... only thing I do know is it sits in a fixed trimmed up position. Is this the right way to have trim or the previous owners cheap way to have a trim system? Can I adjust this so the trim is neutral? or all SJ's like this?

I wonder because now that I'm learning jumps, etc. I'm having trouble landing and keep going or the nose wanting to come too high like I'm trying to BF. I know my weight is a factor at 6'4" 240-250 #'s soaking wet with the landings, but I've countered that a little by not riding with both feet back in the holds. I haven't even hit the ocean yet with the ski, but with it this way there'd be no way I could land cleanly off of any kind of surf....

P.S. Yes, I know loosing weight is a valid option, but that isn't a next day fix... I know other big are out there riding...

well on a level playing field i don't think your weight and height have much to do withthe attitude of the ski jumping, it's a mater of getting a feel for the sweet spot of the ski and getting your weight in the right spot,

that being said, the nozzle , if pointed in the wrong direction will fight you.
i can't asnwer the first part of your question though, sorry i know nothing about yamaha nozzles

i have a raider (i think) nozzle on my SJ. it doesnt have the vanes in it like the SJ nozzles that ive seen. mine points straight back... i didnt notice any upward tilt to it. are you sure its not just the steering nozzle thats pointing up?

Yeah, it is the steering nozzle that's fixed in the 'up' position... and from the looks of it there doesn't seem to be a way to adjust it? Of course I haven't pulled it but there is some tab the looks like it only has one setting, which is up.... :dunno: To give an idea on how much its trimmed up, a small part of the jet thrust actually hits the rail lip on the back of the tray..... No vanes in the nozzle or venturi either.

I don't think its anything that has fallen out.... there's a bolt in an arm at the top that looks like it would move to lower the trim, but it's not slotted or have any other settings so I don't see how lower it.

I don't have pics and won't be down my beach house until the 29th but might be able to get someone to snap some pics and send them to me....

Like I said, I haven't taken it apart to actually see for myself, I'm going off assumptions that it can't be moved. :banghead: But have looked closely at it and if it looked like it could of I already would of done so.

But I did want to confirm that it shouldn't be trimmed up full time for a cheaper alt. to even the C.A.T.S.... since I'm the only SU rider around my imediate area I have to learn all this over by myself.

Thanks 4 all the replys, I work on the pics... so at least I can confirm what nozzles these even are.

Funny. I was just talking with someone on the idea of running exactly what you have as a quick-change fixed trim up alternative to a lever-controlled system. On flat water, I find that I am holding onto my trim 80% of the time, either to make a setup wake or to nose-up going into a wake/wave.

(Disclaimer for the following, as I am not near my skis and am stating this from memory)
All fixed-position OEM Yamaha steering nozzles that go onto the 144 pump have a 3/8" (approx) hole in them on the top and bottom. They are inline with each other (looking down from the top, you should be able to pass a rod straight through both holes).

Then, there should be two 3/8" (approx) collars, thicker than the walls of the plastic, that the two mounting bolts go through. The collars are a stop for the bolts so that the steering nozzle can turn freely.

If you have anything other than this I would say that it was modified, or it broke.

Hope this helps.

alright, here's a pic... it doesn't do the angle justice but you can see the piece I have circled that holds the trim 'up'. From preliminary looks as stated, it doesn't look like it's adjustable.

Do you recall if there is a collar attached to the piece that you circled? A 4-5" (approx) collar that fits in the space between the steering nozzle and reduction nozzle? It looks like you have a trim system that someone just never hooked up teh cable and is sitting in a fixed position. If so, you can likely replace the fixed bolt with a stainless spring to get it back.

Yeah, that's a Waveraider trim setup locked in position, I'm quite sure. If I were you, I would engineer a way to fix it in the straight position, like I mentioned, maybe just a spring. As you progress in riding, you will want that trimability and all you have to do is run a tube and cable through the hull and you have a trim system (might be able to use the stock siphon pump tube to run the cable.

So basically I have the nozzles already for when I'm ready to install the C.A.T.S.? Nice.... :biggthumpup:

Looks like I'll rig something up to trim it down a little until my riding skill progresses enough to warrant actually using a trim system.

Thanks 4 all the help..
