What's the I.D. on a 148 reduction nozzle?

[NVJAY775]

Curious what the minimum ID and the max ID can be on one with trim?

Thanks in advance to anyone that can measure one!

Does anyone make a 148mm specific nozzle? I thought we just bored 144's. Max ID will probably be determined by the nozzle maker?

I run my nozzle at 87.5mm. I tried 86 and 90' but 87.5 seemed to be the sweet spot for my setup. I'm running a kawasaki based pump though.

First there isnt a 148 reduction nozzle. The 148 mag pump uses 144 reduction nozzles, so for trim you have either a 62t or 65v reduction nozzle to choose from. The more common 62t nozzle is about 82mm stock (from memory). Most bore to 85mm, but can go up to about 86mm max safely.

You forgot Pro-Tec.

You forgot Pro-Tec.

Thought he was referring to oem nozzle, which is what I think he has.

I beleive you are correct about what he was referring to, but since it is not a factory made part I figured I'd throw those in. But ProTec discontinued their reduction nozzle.

Thanks fellas. Interesting stuff for sure on these. I didn't know 148's were commonly using 144 red nozzles.

Some time back I remember there were a couple guys getting into making some red nozzles with interchangeable sleeves to change ID's, but haven't heard much lately.

ProTec did quit making their red nozzle. There's another that I can't remember the name of, that is thicker and can be bored past the 86 of the stock 62t. But I've also never seen the 65v to compare ID and thickness.

Anybody have pics and or measurements on a 65v red nozzle? How far can it be bored? Can xmetal trim be set up on it, or what? LMAO! Getting deep here… Thanks again and hopefully someone can share some info on these.

Great info and thanks for opting up.

The pair of ProTec setups I had were both 86 stock if I remember correctly. There are some floating around. I had 2 complete setups with trim.

the protec nozzle is designed more like the 65V. holds more water volume. standard bore is 82 and change but the wall thickness will allow it to be bored much bigger than 86mm. the OD on those are 93mm, 62T is 88mm. since the casting is bigger, you wont get as much throw out of it. those are all designed as a drop nozzle and for racing , you dont need or want an excessive amount of drop.

Well I must've had special ones then. I dont remember exact OD but at 86 ID there is a lot of meat left. Waterboy and Propulsion have them maybe they can measure them. They do have a bell shape for more water volume which I was told actually lost 1 mph on back to back testing with a Stalker gun. There are a few on eBay. Edit: we all have preferences and mine is the ProTec for sure. Stock is 10° of throw but I got one from Retrosud I beleive that was nicely modded for 20° of throw. Once modded you can still easily reduce the amount of throw.

 

[NVJAY775]

It'd be nice to keep the throw.

I forgot to mention that this would be going on a 900 cc ish, or bigger engine. Just not right now, but hopefully soon lmao!

I'm looking into opening one up more and see what can be achieved with a 144 pump. It's basically a budget thing I'm thinking about. I'm just not completely buying (understanding) the need for the larger pumps, when one of these may be able to come very close to, if not match some flows when set up right. 155's and 160's are obviously huge, but possibly a 150. I'm going to go and BS with a pump guy soon and pick his brain a bit on this.

If someone can explain to me how the larger pumps work so much better than a smaller pump, if both are set up to flow roughly the same? I'm really curious, because at the moment I'm not really getting it lol.

Sent my number. Give me a shout and ill tell ya what I can. It's a ton to type.

thats ass wipe throw. all production trim nozzles advertise 30*. nobody is going to want less throw on any 140/ 144mm pump. 148 and 155 with huge power needs less throw to add height instead of rotation. unfortunatly, i've always needed max throw to get around with the under powered boats with my gorilla weight on them. thats all gonna change with my XS1200. i'm gonna use the stock 65U reduction nozzle and trim ring with the stock rubber flow guard. back in the day, serious pro racers used to extend the reduction nozzle by welding on an additional extension ring that barely cleared the turn nozzle. very little thrust escaped back thru the trim ring and nozzles that way. jay, that yellow freak only had a 140 mag and 800cc motor. if the pump/prop is set up right, it will still hit big with a smaller pump. my WDK rev would flat water flip with that maekawa 1000 and a 140 mag.
