Bad day on the Water - Help

[jimraab]

I took my 2005 GTX 155HP out today and the water exhaust hose came off causing the Seadoo to just about sink. Got it towed in and the water was all the way up to the top of the engine. Drained the water and tried to start the engine. The starter would crank the engine, but it would not fire. I checked the oil and it doesn't appear to have water in it. I took out the plugs and cranked the engine. A small amount of water seemed to spray out. I spayed WD40 in each cylinder and cranked the engine again to lubricate it. I have not put the plugs back in yet. What should I do as next steps?

Update: I dried the plugs and put them back in. The engine will crank, but will not start. Any suggestions?

Pour some gas/oil mix into the plug holes and try again (plugs installed of course)

that would be even for a 4-tec? I am really freaking out thinking the engine is shot. Thank you!

Poured a mix of gas and oil into each spark plug hole. Still will not turn over. Could electrical have shorted out? Should I disconnect all of the electrical connections and let them dry out?

 

[jimraab]

The ski just started! Since the engine was submerged in water I would assume I should change the oil just to be safe?

I would take apart every electrical connection, clean and use dielectric grease upon reassembling.

 

[jimraab]

I will do that!

Thank you!

I know you said the oil don't look bad...but you did say water shot outa the cylinder when you removed the plugs and tried to start it...so I'd at the very least change the oil and filter...and I'd clean out the air intake.

With most jet skis, when they are towed you need to use a tool to pinch the feed hose or water will enter the engine while being towed.

I am sure this is what happened to you.

And yes, I would change the oil.


Here is a cut and paste on towing...

What you should know BEFORE you tow

If you need to tow your Jetski back to shore or to the marina you
have to clamp off the hose that supplies cooling water or you can fill your engine with water.

Check your owners manual for the correct towing procedure for your ski.

It cannot be emphasized enough that towing is extremely dangerous. Contact Elephant Butte State Park Rangers @ 575-744-5421 if you need to tow.

Make the fact that you are towing highly visible to other boaters. If the towing boat does not have any signal devices(!), waving
a brightly colored flotation device can help alert other boaters.

If you stop by the shop on the way to the lake Captain Pete will mark the appropriate hose to clamp off at no charge

This way you'll be prepared in the event you need to tow your ski

Since a Jetski that requires towing likely requires service, contact Captain Pete as soon as possible when there is a towing event.

If your ski sinks or fills with water, have it serviced as soon as possible.

If the engine isn't cleared of water and run within a day or two, there is a good chance it's life will be over or severely shortened

Attempting to restart a drowned engine can result in <pictures of carnage here> bending connecting rods and destroying the engine.

Check your owners manual for the proper direction to turn your ski in the event you flip it over.
Turning it the wrong way increases the chances your engine will end up ingesting a large amount of water.

Joe, I was able to get the engine started which is good. I will be changing the oil, filter and plugs this weekend. I checked all of the connectors and they seem to be dry since many of them look to be water tight.

Thanks!
