I thought the whole idea of the flowguard, was to eliminate the chance of thrust entering the exhaust creating a bog in the motor??

Okay, so spoke with a couple peeps last night about this and it does help with what has been said through this thread and others but the real reason for it is for the back pressure in the pump. Okay watch this video if you haven't....

Towards the end he fills the lower gap with putty/clay and then resin is poured in between the flowguard and reduction nozzle. Once it is dry you can remove the flowguard and the resin makes a perfect cast to fit exactly onto your reduction nozzle. So once it is installed there is no way for water to escape between the flowguard and reduction nozzle. Okay so why this helps....when you hit the throttle and the pump is pushing the water through it and out the reduction nozzle and then through the turn nozzle there for sure is pressure going backwards off of the turn nozzle and it would go between the reduction nozzle and where the flowguard is, that being said, once the flowguard is installed PROPERLY, there is no way for the water to escape between the ruduction and flowguard, thus making it go out the normal turn nozzle flow. I work with farming pumps and I just know that 'our' reduction nozzles aren't big enough to allow ALL the water to go out, especially with the engines we are using now days, there is definately back pressure in the pump escaping and this is what this was built for. Again it also helps with ther problems that have been talked about already but this is really where all the gain comes from.

that is a huge project to instal them things... wow!!!!
Yea I had no idea!
Some shops are using a flexible plastic, metal, and/or rubber extension on the fixed nozzle to seal the gap at full throw. This is a cheap and easy way to do it with existing parts. A better way would be to use a Kawasaki ZXI style steer nozzle with its hemispherical bucket and a rigid bulb attached to the fixed. This would provide a fully articulated seal.

i like the bpipe coupler seal idea...quick cheap and easy
the coupler is only good for 4' of additional height though

This seems to be the best idea yet, at least for surf riders. In the Flow Guard install vid, I noticed that the Rickter nozel already had some sort of rubber extention on it. Do you have a link for a shop that sells something like this?
For the poor mans route, The B pipe coupler is a good idea also!

Before I do a search (I'm lazy) Do you know what model? Are they a bolt on swap with a SJ?

you're a tool if you believe that. More power your ski makes the better they work, but they work either way.

if you look closly in the the vid you can see the rrp flow guard doesnt extend far enough back to do much with the steering nozzle,they use the gp800 trim ring with the rubber built in for that purpose,the main thing its doing is keeping the pressure loss behind the trim ring from moving backwards into the pump,thats why they are filling it with epoxy,their whole reduction nozzle setup fixes a few issues,I was looking at it closely on roks ski at world finals,they deff had a few tricks up their sleeve. He was getting more flat spin rotation than anyone else by a large margin
