Nozzle boring

[#ZERO]

We were just talking about this tonight,how does the 62t nozzle with a 21 degree reduction compare to the 61x with the 25.5 deg in low end performance if both were at the same 82 mill bore

The 61X nozzle will load up quicker because of the steeper reduction angle and the 62T nozzle will have less resistance which will rev the engine quicker but the bottom end performance will depend on the engine torque curve, impeller type & pitch combination. You may need to consult with your engine builder to find out which might work better for you application or just perform back to back testing to find out which one will work the best with your setup. The same can be said with the exit nozzle size diameters. The larger sizes will move water more quickly which is great for bottom end acceleration but if the diameter is too large the exit velocity will slow down and may hurt your top end performance. The best way may be to perform your own testing with different nozzle types and diameters till you find out what works the best for your particular setup.

good info,Im my engine builder with the help of some very informed buds.Being as though our crew could care less about upper mid and top,Im thinking the 62t will rev out faster with larger 800+ cc motors. this hooker loads the shiz out of the pump at 7 mills cut back also.loosening it up on bottom seems to give much better low end hit. I know there are alot of big motors out there with thrust trim systems and I dont think he offered any of them with custom 61x nozzles. Send me a pm on what you can do price wise for a a group of them taper bored

This actually makes a lot of sense. My 61x nozzle was easier to keep loaded up but I always hit the gas just before hitting the wave. With my 62t nozzle, I can no longer hit the gas before the wave as it puts the ski out of position. Now I'm forced to wait until I actually get on the wake and gas it but it feels like the engine pulls harder up the wave. I'll add some more to what #0 was saying about engine/prop combination. My hull is also lighter and shorter than stock so that alone could be the extra piece of the puzzle in making this particular nozzle work for me.

what angle does skat use on their mag pump nozzles?
