Problem getting new impeller to prime

[WTR4FUN]

Just wanted to get this out there for any new boat owners doing there own maintenance. I have a 2001 boat with 4.3 gl volvo penta. A few weeks ago my impeller broke. I changed it out with a new volvo part and went to the lake. The boat ran hot. Got home and re-checked the impeller and it looked great. Did lots of searching on the internet about this issue. After 2 weeks of research and flushing and taking the impeller apart and putting it back together I finally noticed that I used the new o ring that came with the kit but never removed the original o-ring. The pump was sucking air and could not prime. Once I went back to 1 o-ring it ran perfect.

thanks,

Matt
