I'm having a problem with my boat not picking up raw water either in the water or on muffs. I did a complete raw water pump rebuild with a kit I ordered off amazon. The install went smooth but it overheated when I took it out the first time. I brought it home and started trouble shooting.
I put the muffs on and removed the inlet pump hose and had water to the pump. I removed the outlet and started the engine and no water. I know it must be something with the water pump, is it possible that I got a bad impeller? The few videos I've seen the impeller had to be soaked in soap water and even then it was a tight fit. Mine seemed to slide in without any effort. Wrong size impeller and not priming maybe?
I bought the boat used and have taken it out twice with no over heat problems. The original owner couldn't tell me when he replaced the impeller last so I figured I'd replace it for peace of mind. The impeller I pulled out was a VP stamped impeller, this one in the kit was not.
