HELP!!! Replaced jet pump now it's overheating and taking on water!!

[wc145]

I posted a couple of months ago about replacing my trashed jet pump. I had taken my '97 Sportster to a local shop that removed the jet pump and disassembled it and it was junk. I got a rebuilt one from Dominic Grillo at SeaDooSource.com. When I rec'd I took it to the shop and they installed it, test ran it in the shop, and said everything looked good.

That was about 6weeks ago. I finally had the chance to get the boat in the water this weekend (too much work and bad weather to get it in sooner) and it was a disaster! It fired up fine, we idled away from the dock through a long "no wake" zone, and by the time we got to open water I was getting an alarm, a steady tone, and the boat didn't want to accelerate. I shut it off and tried to restart it and it wouldn't start. I opened the engine compartment and it was full of smoke/steam and water was pouring in through a tube coming through the center of the transom, down low. Every time I plugged the key on the alarm would sound. We ended up paddling it back to the dock at least 100yds while the engine compartment and the area under the floor filled with water.

Sorry this is so long, but can anybody offer me some insight? Are these issues related? Is that tube the water was coming through for the cooling system? After reading the owners manual I assume the alarm was the high temperature alarm. I haven't tried starting it or anything since and I'm waiting to hear back from the shop.

Thanks in advance for any info.

Sounds like maybe some hoses might not be in the right place. I would be calling the shop that did the work.

:agree: use this, as a guide, if needed

Thank you very much for the quick responses. Looking at that cooling system diagram I'd say they left the pick up hose off. That would account for both the water and the overheating.

One more question - will the computer on this boat shut down the ignition to prevent damage when it overheats and the alarm sounds? Or might I have damaged the engine causing it to not restart?

being a 97, think it'll run, until she pops...

dont you have a bilge pump???
if not id recomend it for safty resons above all

Well, I took it back to the shop and they've looked it over (took they're sweet time about it, too), and they're telling me the engine got water in it and they've drained it and cleaned it out but it won't start and there are electrical issues from the water, but it's not their fault. So, now I have one more question - Does the coolant hose have to be disconnected to remove the jet pump? The shop owner is telling me that they didn't touch the hose and never had to go into the engine compartment, that all they did was take off the pump and then reinstall the rebuilt one.

I bought a repair manual CD and it says that the hose has to be disconnected.

Can anyone tell me from their experience whether it does or not?



BTW, there is a bilge pump and it did not work. One more thing to fix.

not on a 97'. Should just, remove the nut hold'n the steering cable to the nozzle, remove the nut/bolt holding the reverse cable to the bucket, and then undo the 4-17mm nuts against the hull. Now, pull the pump off.
