Super Jet nozzle size

[piratelife]

So i have a question about nozzle size. I just sent my nozzle to zero and had him taper bore nozzle to 84.5 Im thinking of sending another one to him and boring it to 85.5.......Im currently running a 13/17 concord....Will i feel a big diffrence between these to nozzles

Dont go 85.5 its too thin, we just had one break

so what about 85mm ????

I always ran 85, then I went 86.2 which I broke. I am now running 85.5 and it *seems* to be fine. 85 is safe.

For flatwater youre fine, but surf broke the 85.5. If you have one at 84.5 and you go to 85 you are not going to feel a difference. 3mm yes, less than that, try a stock nozzle and a cone or a cone and the bored nozzle. It will give you more options.

since were talking nozzle sizes would an 85 be hood for a 9/15 hooker on a stock 701 (head, pipe, msd, reeds, light. flywheel, light. couplers, ww cone) sorry to hijack

I ran basically the same setup with good results. You may ditch the WW cone. Experiment with it.

Bigger nozzles have a two fold effect when you are over propped, it makes a difference that is easy to feel. If the prop/nozzle is already perfectly matched to the engine then acceleration will seem to decline faster with a larger nozzle. Too bad A/M nozzles were never big sellers.

Is it possible to go to big on the bore? I taper bored my Sato Engineering nozzle this morning and I punched it out from 82.5mm to 86mm. The SE nozzle is so much beefier than an oem nozzle so I could actually go another 1-2mm if I really wanted to.

Do guys stop at 85.5 because the nozzle gets too thin or because the bore becomes too big for their motor/pump/impeller setup?

Here is the nozzle in stock form at 82.5mm


Nozzled up to a 62T raider nozzle bored at 85.5mm


Check out how much more material there is in the SE nozzle...


Here it is back in the ski at 86mm...

Didn't someone make a nozzle for the 144 pumps that had threaded exit rings of different diameters? They were available for the seadoo runabouts so there must have been yamaha models available at one point...
