Took out my new to me 2001 LS2000 and two issues…

1. Engine compartment and deck storage took on a lot of water. Cleanouts had water on top of them… is this normal (also see photo)

2. Engines had high rpm’s but little speed

Any advice is appreciated

While on the water open the engine hatch, look at the intermediate bearing housings, I would assume one or both are probably bad and gushing water in like when one of mine is bad. Not hard to change though. Make sure you check with the engines running and in forward and reverse detents to see, I gave my port side a little throttle and water sprayed in.

There is a leak thread you can look up on here I think in the FAQ section. Water on top of the clean out plugs is normal, you could put some water on top of them on land to see if they do drain into your bilge area or past the plugs to the impeller shaft. New sealant may be needed and/or new rebuild kit for the plugs. New sealant around the clean out grates wouldn’t be bad idea too.

Your impellers don’t look perfect but I wouldn’t expect that to be 100% your thrust problem. Maybe a tune up would be good with new spark plugs if you haven’t done so.

Cobra EZ-Locks add these to your plugs to prevent them from blowing out during use, as for water on top normal!
 
In most cases of water on top of the co plugs, is water coming up the co compartment drain hose while the boat is in reverse. As mentioned above, the intermediate shaft bearings could be a source of water ingress for a boat of this vintage.
 
Also check ALL your hose clamps as they are prone to rust and fall off especially around the exhaust systems.
 
I would add water on top of the plugs as @Acard7 stated above, while on the trailer. Also post a picture of your plugs and the tubes they slide into. My reason is your picture of the water running from the intake grate. It is either the water on top of the plugs leaking past them or a lot of water in your bilge leaking past the tube/sleeve, item 5 in pic., that is sealed to the locking base for the plugs. How much water drains out when you pull the drain plug in the same picture you posted?
Since you are new to this boat...the bilge is the area below the engine bay and bilge pump that runs forward under the helm and any ski locker in the floor/sole of the boat. If you find the bilge pump, you will see it is mounted over a hole where it draws water from the bilge below. Access to the bilge is by removing the co plug tray, sealed and screwed around the edge of the co plug compartment, under that hatch.

I ran into a similar scenario while testing my ls2k. Make sure your clean outs are seated All The Way down, and click in to place. You may need a hammer and some oil to help. Make sure the arrow is lined up. If it doesn't seat all the way you will be in a limp mode due to a weak jet stream.

You wont go into limp mode for a plug not seated properly or a weak jetstream. And you shouldn't hit the plug with a hammer
 
Using a hammer to work the plug into position was much easier then fighting for half a day. An limp mode was just a way to describe the loss of power due to improper flow. This is just based on my experience with a boat of the same make and model.
