Captain white sox freestyle js300

Here are pictures of my js300 that actually goes!! I have had this ski for about 10 years and managed about 5 tanks of gas in it that whole time due to mechanical misfortunes.











told you it still went!

not sure of the actuall specs but i would say this powerplant has at least 20hp+ !!



couple that kind of hp together with a huge volume pump like this and you better hold on tight!

aftermarket parts;

Westcoast rideplate
PJS Scoop grate
Stainless prop
Pole spring
SJ stock bars
Thumb throttle (comes standard)
NGK spark plug cap.

Old skool !!
:shock: Mint looking js300 mate.

You got way too much time on your hands if you can post pics like that

Come on aquaholic this ski has been waiting for its minute of fame since 1986!! haha

That ski is just ooozing class! I bet there are bugger all 300s left in NZ that run. Good shit Capt

haha its ooozing something! look at the wads of grease and oil in the bottom of the hull from the leaky bulkhead seals!

meh just adds to the charm :lol:

I got a hull so I can finally get my freestyle 300 project underway.

Heres some pictures of the new project.

Over the past months I have been slowly collecting parts to use for this build. You cant just go buy 300 bits off the shelf nowdays so its been a bit like restoring an old rod.


Aluminium Pole


Folded and welded Steel pole bracket (unlike cast stockers)


Kerker js300 drypipe

So the plan is to glass reinforce the whole inner hull sides and bottom, nose and under the pole bracket, whack some footholds in and a new mat then swap everything from my running 300 over. Engine, pump and electrics. I also have a mikuni single 38 and manifold to replace the 32 thats on it standard. I have standard superjet bars and finger throttle for it and a quicksteer turnplate that came with the pole.

Also Knoxie was good enough to donate a crispy new reconditioned impellor still in its box!

Hey. Did you get this hull off a dude from out west called Ian.

Isnt that turf just peachy

Yea Ian was his name from waikauwau. That Mat is coming off today and footholds going in. I had to hack the storage compartment out on the right hand side it was a bit of a mission but ive got the footholds fitting nice and ready to glue in when I get a chance this week. I worked out where to put the footholds by measuring the distance between the bars and the front of the footholds on my superjet when the pole is down, then put the footholds in the JS hull using the same spacing.

hows this build commin along capt

Are you still looking for any parts?

The project is still moving along I have just stepped it up a gear this week Im having a pole bracket made this week to convert it to a RN superjet pole and wingie is sending some tubbies up for it. Im planning to do a big grind up this weekend to get it all ready for the hull reinforcement. Should be good for summer.
