Bucket Method not sucking water

I tried to run my 83 Nautique in my driveway for the first time using the bucket method that is listed all over this site. I took the large hose off the water strainer and put it directly in to a bucket of water, but with the engine idling it was not sucking any water through.

One of the manifolds had a slow drip leak out of one of the plugs, but other than that, I couldn't see anything wrong.

What should I check for?

I am almost positive I used the inlet as it was the bigger diameter hose and was leading to the engine. It was the one running under the driveshaft like in the picture here:

I have not replaced anything on the boat since I got it. What is the RWP?

Matt,
Your link didn't work so here's a new one.

I saw the picture with the hand pointing to a hose. If that's the one you used, it's the outlet and not the inlet. It goes from the strainer to the trans cooler. From the trans cooler, it go's to the RWP. Did you try to prime the suction side of the RWP in any way? Pouring some water down the suction side hose is always a good idea.

Have you ever run the engine without water even briefly? If so, there's a good chance the impeller was trashed. It's water lubricated. Even if you haven't run it without water, I suggest taking a look at the impeller. It's in the RWP!

So I hooked up to the wrong hose then? The one I connected to routed to the front of the engine.

I only ran it for about 7 seconds waiting for the hose to start sucking water from the bucket. The exhaust manifolds were barely warm.

Spoke too soon. I took the impeller off and 2 of the fins are cracked halfway through. Would this be enough not to pull any water suction?

Matt,
Take a look at this thread to make sure the RWP orientation is correct for the engine rotation.
