Question about steering nozzle

[Trikes]

I just purchased a 1995 Seadoo SP. Quite good condition. My first entry into the Seadoo and PWC world. The prior owner had mentioned that the rear piece (I now know to be a steering nozzle) was not the correct one for the model. But he also said it works fine. I am trying to find the right one but I am a little confused. I've spent a few hours on line today searching for replacement pieces and trying to learn about the various parts. The online exploded parts diagram for the propulsion system for the 1995 SP shows the steering nozzle connected to the venturi, and the venturi does not have any side pieces that project out for (what I believe to be) trim ring connections. Because these are omitted the steering nozzle can have a simple side piece sticking out to connect to the steering linkage. But the venturi on my 95 SP has those side pieces and the steering nozzle's connection to the steering linkage is a J-shaped piece. Also the inside of the steering nozzle is just an open tube, and does not have the vertical metal piece down the center that should divide it in half. I am wondering if my SP has a replacement venturi and steering nozzle. Any chance that is the case. If so, is it okay to have a steering nozzle that does not have the vertical metal divider piece. (Note, it is not that that piece has broken off. It clearly was never in this model of steering nozzle.) What purpose does that vertical divider serve? Will the ski's performance suffer without it? I know I have a few questions here, but hopefully someone can help with some of them.

Split nozzle was introduced in later models to help with some degree of directional accuracy, but also to some extent, strengthen the assembly. Later models had the extra arm for the trim adjustment which offered better handling at the touch of a button (or manually with a knob).

Obviously they made reasonably successful boats without the divider. So you shouldn't lose sleep over having the wrong one. I would think it is a nice sleeper upgrade to a historic boat.....looks stock at a glance.
