    Steering nozzles

    How many different variations of steering nozzles did Polaris make? Did they come with different diameters? Different lengths? Let's get some pics in this thread along with what the nozzle is from and maybe even the diameter of the nozzle so we can see what differences there are.

    Here's one from a 1994 SL650 - Non trim - 89mm diameter

    Don't get confused with the different jet pump exit nozzles, both Polaris and aftermarket.

    Steering nozzles I know of;
    5131363 1996-1997 Hurricane, also 1999 SLTX-B (X-45), SLTH

    5133868+5133569 2003-2004 Octane
    Note: not a 148mm jet pump

    5130999 1999-2004 Many models (with reverse?)

    5130960+5431765(Trim) 1994-2001 Steering with trim (or reverse?) Pro 785, SL, SLH, SLX, International SLTX?

    Note that the various steering nozzles also differ in length and the provision of mounting bosses for reverse bucket pivot or trim nozzle attachment

    i believe the hurricane nozzle fitting anything else isn't correct as it won't clear a reverse gate.its about 3/4" longer than a standard nozzle for say a virage tx with reverse,but can't be used with trim.

    The one pictured is a 5131048 (89mm exit diameter), apparently used only on the 94 and 95 SL650's.

    How would the length and diameter of the steering nozzle affect performance?

    The steering nozzle will really only effect the direction of travel, however, it needs to be the same size as the exit/reduction nozzle. The reduction nozzle is where the action is at, and it is where the power is made. Without getting into some rediculous calculus, and flow measurements that employ some nasty physics, just understand that the engineers at Polaris were some smart cookies. That reduction nozzle considers the engine's peak rpm and torque range, the pitch of the impeller, and has been designed to produce max thrust within the best operating ranges of the impeller, and engine. Hope that helps....

    Well....i got my trim nozzle out of storage and measured it's diameter. It is quite a bit larger diameter than my non-trim nozzle. Then I checked the one that came with my SL project (it was cracked by the previous owner). It is an even bigger diameter!!! Even with the crack you can tell it would be a much larger diameter with a thinner wall. It has not been bored out either, factory paint on the inside! Now I need to figure out what the heck is supposed to be on the ski.

    Anyone with a '94 SL650...what's your diameter?

    Or you could just pick one up for 10 bucks and bolt it up.

    Can you put this in table format, to make it easier for us at home to follow along?

    Part number, year, inside diameter...

    If you are looking at the inner nozzle for the trim, the one that steers, yes it is larger, however the nozzle that is bolted to it that controls the trim is smaller.
