Changed my impeller plugs and fuel filter and everything seemed to go smoothly. Engine was running great before I performed the maintenance. Put muffs on and let the engine warm up. Put it in gear and everything seemed great. Put it in reverse and the lower unit was clunking every few seconds. It was almost like the gears were broken in the lower unit. Forward it seemed good but reverse it was not. I turned it off and restarted only to hear the same thing again.
Mercury 115HP 2 stroke.
Wondering if I need to take it in and what I could have done wrong changing the impeller to have caused this. Please help!
