A little update...I ran the boat today at a lake and I noticed 2 things:

1) It was pissing sh*tty (again...right after a COMPLETE water pump job) and the pee stream was lava hot
2) It was still squeaking after a WOT run

I headed back in making sure the motor wasn't overheating, which it wasn't. When I got back to the house I took the "filters" off of the lower unit and took a hose to the pee tube on the motor. I put the hose sprayer on the "jet" setting and shot it through for a couple of minutes. I reinstalled the "filters" to the LU and hooked it up to muffs. The motor pees fine now. I ran it for at least 20 minutes, increasing the rpm's sometimes. Seems good now.

Next issue is the squeak. When I was heading in to the ramp I had my fiance steer and I listened in on the motor. It's not coming from the motor at all. In fact, it sounds like it's coming from either the exhaust housing or the lower unit. I checked the gear oil and it looked fine. Now, the question is, what could be causing a squeak from an exhaust housing or LU ONLY when coming off of WOT?
