Water leaking between lower unit and top unit

[Knightran]

Any ideas before I pull lower unit, just curious, thanks

I don’t think there was a 4stroke 90 in 1994

I’m sorry it’s a 2008. I’ve pulled the lower unit and rebuilt water pump, still no water flow. Removed thermostat. But the first time I was reinstalling the lower unit it was misaligned cause the shifter wouldn’t work, is it possible I’ve pushed the water tube up too far also

Woodruff key slipped out of the impeller during installation?
