Trying to iron out the few remaining issues on the motor and it was suggested to check the recirculation check valves. I pulled all 4 of them and they were toast. Removed the mesh screens and the black rubber inside was a gooey mess. I am going to replace all 4 of them as I can but for now I have to leave them be. The boat runs (though idle is shoddy) so it's not a huge priority.

For a temporary solution, can I use an in-line check valve? I have a handful of nylon check valves that are kind of like the ones in the link below (not the exact valve). The ones I have fit perfectly in the hose. They require very little pressure to open and can withstand quite a bit of pressure, but I have no clue how much pressure the recirc system actually creates. Thoughts and ideas?
