I just replaced my impeller and I took it out the next day. about halfway through the day the rpms would slowly drop, like i would have the throttle in place and they would just slowly decline, when I got home to flush the engine I noticed the rubber seal was leaking, I was wondering if this could cause the drop in rpms

A little water leaking out would not cause such a problem. Air leaking IN might, but it would have to be a pretty big leak.

Give us a little more information to go on here:

Was replacing the impeller a preventative thing, or had the old one failed?

Can you tell if the engine is overheating?

Would you recognize the signs of an overheated engine, without looking at the gauge?

How far did the RPMs drop, and did they ever come back?

Does the boat sound the way it used to? Any increase in exhaust noise?
