2000 Nissan (NS25C3) losing power

[BassNBob]

My 25HP motor is losing power as the day goes on. What could be causing this? Just had a water pump installed and is doesn't seam to be peeing good as it should also. What could be stopping it up?

You have to troubleshoot the engine to determine what is wrong with it. Your water pump problem could be as simple as a clog in the pee tube...Or it might be anything in the cooling system. Again, troubleshooting the engine is the only way to determine the cause.
