Super Soaker 300 - The Ultimate Water Gun Experience

SS 300 Box Pic

Up until 1993, in a land that would have been rampant with people frantically fighting with mostly Super Soaker 50’s, mixed in with a decent amount having 100’s and the odd biggest on the block with the 200, nobody probably would have predicted that Larami would release from their captivity, something way more hostile just around the corner.  They did though, in the form of the 300, it basically redefined what terror in water fighting was back then, and even to this day coming up against one still is.  The 300 is basically like the Alien Queen among Super Soakers.  The 50’s and 100’s are like the runners around it, the 200 is basically a Praetorian, which leaves the 300 as the big, slow but hugely aggressive Queen who will kill in a flash with one fatal hit.  Only way back then you could beat an SS 300 user was to hope that the person using it wasn’t a very strong person to the point where the sheer weight of the backpack or gun filled with pressure would imbalance the user.  Thankfully many kids who got them back then had this problem, however among those would have been somebody who could manage the weight, in which if that happened you may as well have held your hands up, try and be on their side, or hope they trip over and break it, which did happen to a lot of them back then.


As the box stated, it is ‘The Big One,’ welcome to ‘The Ultimate Water Gun Experience’ page, about none other than the legendary Super Soaker 300.  The CPS 2000 may have set a benchmark for being able to fire a constant stream of over 20oz of water 50 feet or so, but what we seem to forget is that if we are just talking about the first gun to reach the 50ft barrier, then the 300 takes that one, as it could shoot 50 feet as stated.  The 300 really did boldly go where no other water gun has gone before back then, in which not many blasters have been since either.

Recently, I luckily managed to get a new one again after 6 years of stupidly selling my previously new one.   You’ve seen the box, waiting for it to break out, so let’s unleash the beast (no I’m not talking about that shitty UK TV series that has just come out) from its cage!

Opening Time


As you can see, if you had been used to later blasters from the CPS age, or later air pressure blasters after 1994 then you would have been in for a shock.  I know what you might be thinking, ‘WTF, it’s broken,’ nope, not broken, just not fully assembled.  That’s right; YOU had a part in creating this monster when you get it new.

The main parts we need to fit on and complete the gun and backpack, are in the small box the gun in its current state is over the top of.


Aside from the sticker sheet and instructions which I’ll come back to in a bit, all the parts we need are here.  There is the hose tubing (which as you can see is kinked on this example, we’ll get to that later), a small bag of pieces we need on the left, the trigger handle lever and the backpack attachment piece.


Next is the sticker sheet, due to the 300’s rarity now, I will be leaving the sticker sheet unused.  I remember last time it was quite a fiddly process putting them on.  Besides it looks cool enough without them.  I will most likely photocopy them in the future onto sticker paper so I can stick them on, but also leave the originals unaffected.


Another closer look at the attachments inside the small box, held down with wire.
Next, let’s see what is in that small bag to the left, which reveals more important parts!


And yes, the gun handle, backpack straps and the backpack reservoir caps (yes Larami left it to you to put those on as well!).

The Instructions

Usually instructions on stuff like this are pretty self-explanatory and don’t really need any mention.  As it is usually just fill up, pump and then pull trigger, so pretty bog standard.  However on this occasion, the SS 300 came with a double sided leaflet, which for a Super Soaker is like having a manual!  Not only that, I’m also going to show it because some of the things Larami wrote on it made me laugh and made me think that the guys at Larami themselves had a sense of humour, as well as the feeling that they were really involved with this, as if they had a general passion for Super Soakers just like we do.



Now it is on the operating instructions page on the other side where some interesting things are mentioned.

-‘The backpack does not have to be full.  Fill with only as much water as you can comfortably carry.’

I don’t remember seeing it being worded like that on any other backpack blaster, it just said fill it up to full.  It’s almost like Larami knew that certain users wouldn’t be able to make full use of the blaster with a full backpack, so they said you didn’t have to.  It’s almost as if there is an instructor reading it to you or something.

-‘Turn tank valve lever to the “on” position (Figure # 10) and continue pumping until you feel maximum pressure.’

Now the main part in this bit is ‘feel.’  Yep, the SS 300 (along with the XP 250), didn’t have any form of pressure valve, Larami left it up to you to be responsible enough to know when to stop pumping.  No stabilisers, safety net or safety barriers here, there were no limits (well unless you pumped it to the point of explosion like on one of those comedy sketches).  It is kinda what makes the SS 300 have such a personality, as it is like you need to be at one with it, almost like something the user must master and show respect for.

And the final quote I found pretty funny.

-‘Release a drenching stream of water by pulling the trigger handle.  Because of the large amount of water, use the gun outside only.’

Well duh, using the SS 300 indoors would be like wearing casuals to go up Mt Everest, you just know it’s gonna end badly. I reckon Larami put that there as a bit of fun to show they had a sense of humour.


Now with all the parts seen, it is time to start the job of assembling the SS 300 into life.  I think the reason the 300 is unassembled when you first get it is most likely to do with space and keeping costs down when Larami would have shipped them out.  The smaller package they can get it into means the ability to ship more at a time which helps money made and allows more bulk shipments.  Also better for shelf space too.

Hover over images to see assembled parts on and off.

The first part I’ll be fitting on is the handle for the gun, which is a one way fitting unless you open the gun, so basically once it is on you cannot pull it off, you also cannot fit it back in the box anymore, hence my space/shipping cost theory.  It is a simple operation, it slots in without issue, make sure you get it on the right way; you don’t want to make it look like genital parts are on the wrong way around.

Attaching Handle

The next part is fitting the trigger handle lever over; it is the same as last time really, just slot it over easily.

Attaching Trigger Handle Lever

That is the gun finished; now we move on to the backpack.  First of which is the connection piece which is needed for one end of the tubing to connect to.  These consist of two screw threads to connect it.  You have to screw these on fairly tight; if you don’t then the backpack will leak from this connection when you fill it with water.  Interestingly as well, the thread connection closest to where the backpack tubing connects is the only one that water filters through, the other thread end to the backpack is fake/cosmetic and is purely there as a stopper/wall to stop any water leaking out.

Attaching Backpack Connector

Now on to attach the backpack straps.  Following the instructions as you can see earlier it is rather simple, however at the same time you need to take your time with it and concentrate so you don’t end up with it tangled up or on the wrong way.  You wouldn’t come to a party in an inside out shirt or with buttons badly aligned, the same applies here.

Fitting The Backpack Straps

Finally all that is left is to screw the backpack reservoir caps on top, that is pretty self-explanatory really and takes two seconds.

Reservoir Caps

The Kinked Tubing

Before this SS 300 can be used to its full, those tubing kinks need be gone.


It was kinked in two places, here’s how they were dealt with.  The areas needed softening first in order to reshape and unkink them.  So, they were put under boiling hot water in a bowl.


After it was set straight with no annoying kink anymore, to seal it, cold water was then run over the affected area so that it wouldn’t kink again.


And kinks hath now disappeared.  I’m referring to the band either, although they aren’t really prominent anymore either!


Blast Off

The SS 300 - Ready to rock!

Hooray, we can now finally take the ultimate soaking machine out for a spin.  Here are some pointers on using it and how it feels.

-The manual states to pre pump air into the chambers (air pressure blasters benefit from this in general), however even if you don’t with the 300, because it’s pressure chambers are so high pressure and can store a massive load of water then the end result when you pull the lever is still impressive.  Some people have even found not pre pumping air in gives a better result.  This is going back to earlier about the user mastering it, it is one of those blasters that has certain sweet spots you will find out with time.

-Providing you don't act rough using it, the 300’s fragility won’t seem like such an issue.  It is still not a blaster I’d use in the heat of things all the time due to rarity, however balance it out and you can still get a nice amount of steady but controlled and balanced effectiveness with it.  The SS 300 is basically meant for building up to those one hit devastation attacks every once in a while to make enemies know who still is King, or Queen of the hood.  This is where the controlled and balanced effectiveness comes in if you are using it.

-The whole idea of feeling maximum pressure also is not as bad as it seems.  It is not too hard to know when enough is enough.  What I’ve found is that towards almost maximum pressure the pumping will get slightly more difficult however you can still get some more pumps in without uncomfortable resistance.  After that you will notice it pretty much stop to the point where any more movement of the pump in wouldn’t be wise, so even if this happens while the pump is halfway or three quarters of the way up from being fully retracted then just stop.  It’s a tracked pump so you shouldn’t really worry where the hell it is!

-The trigger handle plastic that the spring pulls on provided you use it unaggressive is pretty much not as unstable as you think.  Make sure the spring doesn’t rust by storing it well (read Blaster Care), in which along with that the plastic should be fine and you won’t have problems.  Pulling the lever all the way back and a bit more while doing it too aggressively a lot then you risk potentially breaking the plastic, rendering the blaster unable to fire as you have basically broke its connection line.  Imagine it as a set of tube linkages on a piece of machinery.

-The first four seconds of the shot are where the 300 has useable power, in which after that it will drop down (it is a large nozzle!).  Along with that, the first second of the shot is where output, power and range are at its highest, so make it count.  It might be short, but what a blast!

-This is just personal experience, but I have found that as Larami state, pre pumping air 12-14 times before pumping the blaster up with water gives a better result than just pumping with water from the backpack straight away. The range is better, there is more of a punch to the stream and the stream stays at high pressure for longer with less drop off.

And there we have it; hopefully this guide was of use or just of interest reading.  It wouldn’t be complete though without action, so I shall finish off and leave you with a full completed shot compilation video of it complete with all action music, to show off the Super Soaker 300 in all its glory.
