Bilge pump hard wired to the battery?

Just purchased this 98 xp limited and I missed a few things when i purchased it. Under the rear hatch when installing the new battery I noticed the the past owner had the bilage pump hardwired to the battery and had the ground wire hooked up to just unplug from the battery when not in use. I would think the bilge pump would either be automatic when water is detected or when power is on and ski is in use.

There is a wireing plug that is wired from the factory directly about the pump and both wires bare just hanging down, no idea what they go to. Maybe the pump? orginal but maybe looks like the old owner bypassed something and wired the pump directly to the battery. I posted a picture on another post but it has not been published yet. If someone wants to find the post and respond that would be great. search bilge pump.
Thanks
 
Last winter I installed a bilge pump, and hardwired (more or less) to the battery. I used a rule PWC, automatic bilge pump, wired it through a switch mounted on the dash, and a 3amp fuse to the battery positive, and direct to the negative post. So when the switch is on the pump automatically checks every 30 seconds for water.

When I leave the ski at the lake, I have a 1.5amp battery tender that I leave plugged into shore power or I have it plugged into a solar battery charger. So far its worked great.

when you say automatically checks every 30 seconds, does it power on then look for water then power down or does it have a float system of sorts? I hooked this one up just to see if it would run and did not leave it on more than 5 seconds, it is not fused and this sort of fly by night hook up does not fly with me. Everything needs to be fused. Would it be safe to say that this is an aftermarket product? Does the XP limited come with a pump? I checked the shop manual and I see a pump but not sure what I am looking at.
 
The pump checks for the presence of water, I suppose it has a couple of electrical contacts and when there's water if keeps the pump running, there is no float. It's a Rule Model 24S-6WC, 500GPH Fully Automatic. You can look it up on the internet. I added this because sometimes I will leave the ski at the lake for an extended time. That's why I use a battery tender plugged into shore power.

A bilge pump is not factory equipment, there are two bailers in the hull that work off suction from the jet pump, if you are just going for the day the bailers are sufficient, check and see if yours are still there. The other option, if your bilge pump is running continously is to add a float switch in series with the positive going to the bilge pump. You really don't want to leave the bilge pump running because it will drain the battery and ruin the bilge pump.

that is... not accurate.

The electric bildge pump on the XP IS FACTORY.

The connector above it has blue and brown wires (I think, this is from memory). I have a 2002 at home.

The XP has the bailers AND the pump, and with the way I ride, it needs it. the XP sits really low in the water and takes on water... ALL the time.(I can sink it up to the handle bars any time I want in the corners)

The RULE one you have, and I have spins the motor every 30 seconds and if there is a load (water) it runs for 2 min, then checks again.

The XP provides power to the bilge pump only when the system is ON. so when you hit start (once) it will power the pump, or while the engine is running.

it took me a few days and tests to determine how all this was setup.

there are also bildge pumps that run 24/7 without water without damage. I would almost prefer this kind of pump as it would just spin any time the engine was on.

the factory hookup won't provide power to the pump if the engine is off... so for storage it doesn't do anything. Only while the craft is... ON. if you pull the fuse cover on your MPEM there is a 3 and a 5 amp fuse... it's one of those.

I found that out since the one I bought the pump was shot and kept blowing the fuse... until I wised up and unplugged it. (20 pages of manuals later).

Does this video work?

It was freaking cold that day (last day out 2010)... and I had a full tank...

$3200 for the ski, $1,000 for a new engine (didn't know it was going to blow up)... the best $ I've ever spent in my entire life on anything, ever. PERIOD.

The XP has obliterated my expectations and I am beyond thrilled with every inch of it.
My $55,000 tahoe however is a piece of $hit...

Good to know, I stand corrected. I put a deposit on a 96XP, am going to check it out, ride it, and probably purchase it this weekend.

I will probably replace and rewire the bilge pump like I have it on my GTI so I can leave it at the lake also.

I've never been impressed with the SeaDoo bailers.

I have a 00 xp and the oem bilge pump runs Luke ever 30 sec with the ski on or off I just unplug it when I'm done and out of the water I usually don't even plug it in my ski don't really get water in it at all so it's up to you on how you want it wired
 
How long do you leave your ski in the water unattended? I sometimes leave mine in for a week or more. Even if the ski doesn't leak you still run the risk of rain, or water getting in from wake, or storm.

Well I have only had it out once and that was when I purchased it, but we plan on taking it out after each use.
 
I leave it in the water for the weekend all the time and have left it in for a week with no problems with the pump unpluged and no water in it at all the only thing that happen was at low tide the ski went under the dock a little bit and got stuck at high tide so if your in the ocean be carefull were you tie up
 
I guess we're just going to agree to disagree because I have found considerable water in the hull after leaving the ski in the water for a week, that's the reason I added the bilge pump in the first place. Not real sure how it got there, I don't think I have a hull leak, but we did have some bad storms the week it was in the water.

I have a 98 GSX Limited with the 951 and it also took on water quite a bit while stunting around.

I also hooked up an electric (water level sensing) bilge pump that dumps the water out through the seat breather temporarily till I could find out what was going on.

I did not want to drill a water exit hole in the doo.

After doing a carb rebuild I noticed on the underside of the exhaust a corroded hole in the pipes water jacket and of course the water came in to the Seadoo through that hole. I confirmed it in the water while strapped to the trailer so I could run up the throttle and check for water entering. You could not tell at idle.

I removede the exhaust, ground out the corroded part, used another close fitting peice of aluminum sheet to close the hole and liberally applied JB Weld to secure it all in place.

Problem solved, no more water comming in like crazy, but I left the bilge pump in it anyway for those submarine stunts that invaribly get water inside.

Love the Seadoo with the Rotax 951, an amazing powerhouse that literally launches you in what ever direction your pointed (mostly into the air) I would never buy a PWC with anything less peppy now.

The (125 lb) Girlfriend however can almost keep up on the 99 SPX with its 787 engine.
