Steering Nozzles

[N3vrSat1sfied]

Anybody know pro tec nozzle specs
I know GP1200 nozzle is 155 pump, 92mm bore http://pro-tec.us/extended-steering-nozzles/114-steer-nozzle-50mm-gp1200-all-gpr-black.html

I am looking for a 155 with an 89 or 90mm bore (ll buy a used one if anybody has one). I emailed pro tec but thought I would post here in the meantime..

Thank you

91.7mm

Can't recall what stock was on a GP12 steering nozzle but I believe they were in the 91.5~91.7mm range.

Ya gp1200 is 92. Which works on my dvx. But need something smaller for the fv1 like a 90 so I wasn't sure what size the xl1200 was

Stock XL12, GP12 and GP13 nozzles are the same unit. http://www.partzilla.com/parts/detail/yamaha/YP-66V-R1313-01-00.html

Not sure what's smaller. Modified runabouts rarely shrunk their steering nozzles.

Maybe blaster 2?

Pro tec said all their nozzles are 92mm

Sounds about right. 91.7mm ID factors in the thickness of powder coating at around 0.15mm.

OE nozzle sizes on the Blaster II, GP7 and GP8 are all the same so I'm not sure of a factory Yamaha nozzle that would work. You might find something from a Kawi or Sea-Doo that fits the bill.

You might try calling Hot Products. They have a ton of odd data like that.

thanks, I might try a plastic 87mm but that might be too small.

Ideally you want your steering nozzle around 3mm larger than your reduction nozzle. 2mm can work depending on your setup but anything smaller and water tends to try and revert through the front, especially with extended steering nozzles. There's a point at which the system starts choking itself off.

yes exactly. Its currently running a 89/92 combo but doesn't seem like I can find the right size steering nozzle for an 86/89 combo.

Well, if you're trying to move straight forward then it's not working at all.
