2000 Seadoo Speedster 240hp EFI- Help!!

[jconrad]

I have owned the boat for only a few short months. Have not had any issues until the last couple days. Took it out on Saturday and battery was dead at launch. Took back home and put a booster on it and tried starting it with hose hooked up and running to flushinc connector. Wouldnt do the trick. Took back to the launch and jumped it with a set of battery cables. 5 minutes after getting the boat running I realized that I didnt close the flush connector cap. There was water coming out of it with the boat running. Ran fine for a couple of hours, and then took it back home.

Next day hooked it up to a set of battery cables on a vehicle before taking it to the lake....hooked up flushing system and boat cranked over fine. Headed out to the lake.

Started just fine at the lake. As soon as as i started to accelorate the warning light/beeper was going on and off. But not the normal sound of the beeper. almost like a faint screaching sound that you couldnt even hear when the boat was at high rpms. Sounded like something would sound when the batteries are dying. (just an anology.) Shut the boat off to read my manuals for about 15 min. Attempted to re start the boat, and it wouldn't even crank over. Is this an electrical issue? Do i need a new battery, battery looks new. This is my first boat, so any help would be appreciated. Would leaving the cap off the flushing connector with the boat running hurt the engine or cause water in any of the filters? Thanks in advance for your time

NEVER "boost" a boat battery. Jumper cables from another battery are fine, but those "boosters" often increase the voltage to the point that things get damaged. Let's hope that didn't happen here. I suspect all you started with was a bad battery, and hopefully you didn't make it worse.

Classic error, don't feel too bad, many people have done that. Water comes out there because the cooling system is pressurized when the engine is running in the water. Hopefully you didn't run the engine too hard while the hose connector was open because that can permit the engine to overheat.

Depends on where the water went.

Here's what I would do. Trailer the boat. Remove the battery and open every possible drain plug, hatch, door, lid, etc. Park it in the sun and let it bake all day. The idea is to get ALL of the water out.

While that's happening, take the battery to someone like Batteries Plus and have them test it. It needs to be tested under load, not just checked with a voltmeter. If it's anything but in perfect condition, buy a new battery - with the biggest MCA rating available in that form factor.

Back at the boat, look over all of the electrical connectors in the engine compartment, including those on the engine itself. Make certain they are tight. If any are loose at all, completely disconnect those and make certain they are dry inside before reconnecting them.

Again, the idea here is to dry everything out. You sprayed water into the engine compartment for a while. Who knows where it went. You need to open everything up and dry things out.

After airing it out for a day or more, install the (new?) battery and try starting it on the hose while trailered. It should start without problems. If not, it's time to start troubleshooting.

Report back!

Thanks for the info guys! I am going to uncover the boat tonight and let it dry all day in the sun tomorrow, then I will take the battery and have it tested. Hopefully this does the trick!

What type of explanation if any, do you have for the warning system beeping?

One more idea...

If you have one of those big "box" fans, position it to pump air into the engine compartment. I have a REALLY powerful fan that I use that way to completely dry out the boat before tucking it away for the winter. Combining lots of air circulation with plenty of sunshine will speed the drying process.

None yet, but since you described it as a "faint screeching sound" (i.e. something abnormal) I'm hoping it's caused by residual water somewhere and that it will go away once things have dried out and all electrical connections have been secured.
