My 89 Evinrude 90hp is not pumping water correctly. I changed the impeller first, then the impeller housing. After that failed I used a whole different lower unit. I also removed the thermostat to eliminate that as part of the problem. I am getting water flow from the indicator hose (which I believe tells me the lower unit/impeller is doing its job?) but I am not getting any water through the thermostat or heads. Any ideas what might be causing this or what I should check next? Thanks.
I'm just getting steam out of the heads and thermostat.
