NEED HELP with a 7.4L

[src]

The feed line from the outdrive could be corroded/restricted where it passes through the transom. This is a not-too-uncommon problem with the Bravo drives. More likely on a saltwater boat though. Also, you could just have something blocking the water passage from the drive somewhere. Lack of water will toast the impeller quickly.

I had a co-working who spent a year and a half chasing overheating problems, and it turned out that there was a mollusk shell stuck (grown?) in the water intake inside the outdrive. If no water comes in, then work your way back through the system.

Took off the lower unit on the outdrive to get a look at the water passages. Those were all clear. So I read about the water line through the transom possibly getting kinked and I took a look and saw nothing. Next I unhooked the supply line into the raw water pump and forced water from the outdrive through. This produced chunks of rubber Im assuming from the previous impeller. Hooked everything back up and still no water from the outlet of pump. Guess I will just repeat my previous steps and go from there.
