I replaced my impeller recently on my 86 9.9 Merc 2 stroke. I fired it up tonight for a test in a garbage pale full of water and it was peeing fine. I tried it in neutral and reverse. Within a few minutes, I noticed it had stopped peeing.
I shut it down, let it cool then pulled the lower unit off again to check the impeller. It looked perfect. I also checked for blockage as best as I could in the pee tubes and hoses.
When I ran the motor originally, I could not get forward to engage. I later found out that the problem was simply the edge of the garbage pale was jamming the linkage from going into forward. That works fine now.
Could the fact that I had the motor in reverse only with the new impeller made the splines bend into the reverse direction??
Or, should I be getting water discharge (peeing) in reverse too?
Thanks for any info.
