I just thought I would share a few things after replacing my impeller this morning.
It took me about 1.5 hours total, most of that was due to removing and replacing the hoses on the pump. I found that to be the hardest part of the job, and I'm still not satisfied with how the intake hose went back on.
If you have a large bulkhead in front of your engine like me, the use of a mirror is very handy to see where you need to get your tools into and helps inspecting the pump before putting everything back together. I also had a magnet on a string and did need to retrieve the small brass pump screws a couple times as I was finger tightening.
The pump bracket bolts on my engine were 9/16 and I reached them with one eight inch extension, and used a deep well socket to hold the bolt without dropping. an eight mil nut driver for the pump screws, and hose clamps. If you have a bulkhead, a regular length screw driver will not work for you so take this into account when you are planning your job.
The impeller I pulled out was not broken or deteriorated, but I'm pretty sure was the original in the 2000 motor. I noticed the veins were a little thicker on the factory impeller, and they retained their bend outside of the housing. I did replace with a volvo penta replacement not aftermarket. I think it cost me $50.
It all went together as the manual states except for the problems I had getting the hoses back on, I did notice a bracket further back on the two hoses that must keep them from rubbing together, I need to figure out how to remove that before I winterize.
I took my boat down to the boat ramp and lowered my lower unit and let it set for a minute before starting the engine. It's my understanding the pump is below water level so I wanted to make sure I didn't dry run the impeller and mess up my work.
I ran the engine for about 10 minutes and checked for leaks and that the temp came up. I was happy with both.
I'll keep an eye on the inlet hose as this is the one that didn't seat on the pump housing as far as I would have liked.
I'll be out running the boat next week and I'll give a follow up report.
hope this helps someone.
