Second day LS 2000 took a crap! HELP!

[Sgtcolemannathen]

Hey guys. I did do some searches for my issue but would like to ask for some help. We just bought a 2000 LS 2000 yesterday. Test drive it for an hour with zero issues. Today it fired right up and we tore up the lake for about 20 minutes. Then we lost all propulsion. The engines would rev but we would barely move. I pulled the blow outside and could not feel anything. 5 minutes later both engines would sputter. We were just trying to make it back to the dock. The engines started to randomly die and low and behold the engine compartment was now half full of water. We had the drain plug in. We made it back, but the engine compartment was not draining with the bilge on. Idk where that water came from. Any help would be appreciated.

Cleanout plugs not set perfectly will allow water intrusion like that.

Mine are so difficult to get to seat. Any recomendations? Would that cause my power problem?

Absolutely. It would feel like cavitation/impeller slippage/ extreme loss of thrust.

Aside from your engines which may need attention if any water was aspired, sounds like the cleanout plugs rebuilt kits are in your future! Along with the @Cobra Jet Steering LLC EZ locks.

I’m not familiar with the LS models so I could be off. Hopefully experts will chime in, I’m just trying to help with my 0.02!

Cavitation and extreme power loss is exactly what it felt like.

Sounds like there is a possibility your cleanout plugs are not sealing well.

I cant get the port to seat at all. I'm about to put a little oil it. But that wouldn't effect the starboard engine.

It would if it any water made it into air intakes.

Check the oil to see if water got in through the air intake. Port side intake is lower so could be in one and not the other. If so, take pictures of water line in engine compartment for insurance purposes. Also, port covers may seem to secure but you really have to tug at them to make sure. I pour water on mine and they slip right in. And as @swatski said, EZ locks before your next outing. I added a high water alarm too.

If you are on the water and need help with engines dying - you may want to use the emergency tag “@ help” (no space) - just insert it in the post.

That will page expert forum members to help.

Thanks, we made it off. At 4k rpm, port engine about 5 mph

When those things blow, sometimes they lodge in the tube and manipulate the shape of the tube creating an opening for water to get into the engine compartment. When you get a chance, check to see that the tubes are still hose clamped securely at the top.

 

[Sgtcolemannathen]

Will do, headed back to the lake. Will provide pictures also.

Sounds like cavitation and the plug not being seated as others pointed out. If you got water in the engine, remove the spark plugs, remove the safety lanyard, and turn over the engines to get the excess water out. You should then run the engine immediately so you don’t get any rusting. This is very important if you are in salt water but it is critical either way.

It doesn’t sound like you have the cobra ez-locks on your plugs since you can’t install the lock if the plug isn’t seated.... if you don’t have the ez-locks, get those asap as well to avoid a plug blowout!

 

[Sgtcolemannathen]

It does have those, except I cant get the plug back in now. Not sure if it was seated properly before the incident, because first thing I did was pull them to check for obstruction.

 

[sunbyrned]

Some people have suggested swapping the plugs to the other sides. For some reason, that sometimes helps. Maybe try that.(?)

 

[Sgtcolemannathen]

Also, my bilge pump couldn't keep up obviously there was 4 or 5 inches of water in my engine compartment. But it only seemed to leak water into it while I was running it. Kill the motors and I could scoop it out with a large bottle.

 

[sunbyrned]

Was that as high as it got or was it half full earlier? If only that high, you’re probably in good shape engine wise.

Send a picture in 10 minutes.
