superjet tilt nozzle backflips

So I have an EME micro with a Solas 12 vein mag pump with a trim system. I am trying to learn how to do a FW backflip but my trim is very difficult to pull when I hit the gas even a little bit. I am assuming this is because of the force of the water pushing on the nozzle. Does this happen to...

I want to install a tilt nozzle on my 2009 sj not sure what brand I should go with and am not 100% positive of the pumps size
