bilge pump and cdi question

[jedw79]

Hi I have a couple of questions. First is the bilge pump wired to run as long as the engine is running on a '96 sl 700? Just wondering because I'm swapping my complete electrical system with one out of a '99 or '00 setup. I have the complete engine and electronics so that I don't have to worry about the stator issue I've read about. I noticed that there is a bilge switch with the new box, but the bilge still seems to be powered as long as the engine is running. Would this not cause premature failure of the pump? One last question: My new cdi has what appears to be a serial port on it- what is this for? Can it be programmed? Okay I lied one more thing - I'm putting one (single carb.) ocean pro vortex flame arrestor on my ski and would like to know if I must adjust my hi and low mixture. If so, I don't have an adjustment for the hi, only the low; will this be a problem?

Thanks

The bilge turns on when the engine is running. That is normal and doesn't wear out the pump. Some newer models have a manual bilge switch on the lanyard housing. This gives the ability to run the bilge without the engine running.

I am not sure on the cdi having a serial port. I know the FFI models have a port to plug a laptop into.

On my Polaris 700, I added F/A and didn't rejet the high. It is rich enopugh stock that a rejet is not necessary. You might want to richen the low with the adjuster screw but carb tuning over the internet is impossible [img]smile.gif[/img]

Thanks for the reply. I'm not sure what the port on the cdi is for. I was just wondering if all 2000 polaris 700 pwc engines came with a port on the cdi, or is mine just out of the ordianry.
Switching gears, can anyone tell me why three wires are needed on the analog fuel gage? I can see two (ground and power), but the red and white stripped wire is throwing me off. The 2000 is wired for a mfd while the '96 is not. The red and white stripped wire is coming from the voltage regulator so I assume that it is a power wire. However the 2000 voltage regulator doesn't have a red and white stripped wire so I was thinking about hooking it into the orange wire that runs the warning buzzer and bilge pump. The orange wire is regulated to 12 volts and is only powered when the engine is running, so I figure it should be okay. Can anyone confirm this - I realize that this is a "custom" job and therefore may not be easily answered.
Thanks

SL is right, the early sl700 had auto bilge, ran any time the boat was running. they put in the button on the later models for those folks that would occasionaly put the boat in the water without the drain plugs, that way you could drain a little water out of hull without having to start the engine. The port on the cdi box is for adjusting your base timing, if you have the hardware and software, you can change the base timing setting without having to rotate the magnets on the flywheel. Adding the OP filter should be just an install. they are jetted rich enough to provide adequate performance across the widest range of users possible. So....you shouldn't have to rejet.

If you really feel the need to have a high speed screw put into your carb, we do that, heres a link to the machine shop page.

You got me on the wires. Maybe one sends the signal for the limp mode to activate when low on fuel? Maybe someone with a service manual for the 700 can clear it up?

The red white is the power wire for the analog guage. you should verify that this wire has 12 volts when the machine is running, I can't remember if that was a 12 volt wire, or a 7 volt wire. If its 12 volts, then you can hook it right to the orange wire like you are thinking.

Luckily I have a friend with a stock sl 700 that I can check the red and white stripped wire's voltage on fairly easily. The help is/was much appreciated.

My manual says red/w goes to the same "switch" the buzzer (orange wire) does. Check that voltage but I think your right.
