Hello,
I just purchased my first Stand up jetski , 2012 Yamaha Superjet and im gonna receive it on thursday ,iv been told that installing a Bilge Pump is a must on these stand up jet ski's can anyone recommend me a good kit , also what are some necessary parts that i should get for my SJ
Thanks,
What is necessary is going to depend on your riding type and preferences.
The bilge is not required if you are just going to cruise around the lake. The stock siphon bilge and a good hood seal is sufficient for casual riding. I don't run my bilge while racing because the siphon gets the job and I don't fall much. However, if you are going to ride surf at all, be doing fountains/subs, riding aggressively or falling a lot, then a bilge is a must.
The bilge is a mostly simple job. You can just glue it down, but the brackets are inexpensive, so I am going to suggest a bracket. A few dollars saved gluing it down will make it more of a hassle down the road.
You need...
- Bracket
- Bilge (rule 500)
- 3/4" hose
- pipe clamps
- Switch (and bracket if you get that kind of switch)
- Fuse (optional but strongly recommended)
- ring connectors marine heat shrink type
- line connectors (depending on the type of switch you buy)
The bilge bracket for the SJ and the rule 500 is like this one...

Just bolt it onto the through hull pump housing. It keeps the stock siphon bilge. It's what I have, it works well.
I'm not going to detail every step that you need to do to install the bilge. That has been explained here many times.

As far as what other parts are necessary, it depends on your riding style. If you ride surf, a scoop intake will help keep your pump from cavitating. If you race, a ride plate and sponsons will help a lot. If you want more power, you should buy a pipe and a head. Everyone is different. Most people buy a pipe first. I myself bought 0* bars and a bilge 1st. Then a throttle/cable (because I broke the stocker so I got stronger parts), then a ride plate (stock for surf and a new one to race with), made rear sponsons, high compression head, front sponsons, lifter wedges (quicker than footholds). Most people would think I'm crazy for not buying a pipe, but this works for me. (Note I went down the handling route instead of the power route. The only power mod I have is the head, and I bought it used, so it was 1/3 the price of the pipe, and it doesn't change my power curve, those reasons are why I got it over a pipe).
There is a thread in this section called "1st mods for your new superjet". It has lots of advice. Finding answers to the questions you seek are very common and easy to find but you need to look for them a little. Use the search feature.
Anyway, the bilge is a good place to start.
