1982 yamaha 55hp outboard ,water not pumping thru weep hole in any strength
First thing to check: Disconnect the tiny hose between the check outlet and the engine. Disconnect it at the engine side.
With an airgun, blow in the check hole from outside to engine side.
With an airgun, blow out the engine connection.
Start the engine, check waterflow out of the engine connector. If water, reconnect the hose and check the water at the checkpoint.
If still no water at the engine connection: replace the impeller!
Thank you for posting your question here on Fixya.com.
The orientation for a sump pump/check valve are the pump is in the bottom of the pit, the discharge pipe leads up into a check valve, usually very close to if not threaded into the pump discharge, and then the pipe continues up and out to wherever your water discharges to. The weep hole needs to be below the check valve.
The hole is there to prevent an air lock in the pump which would prevent it from moving water.
If the water trapped in the vertical run of the discharge pipe is returning to the pit once the pump shuts off the problem is the check valve is not holding or the hole is on the wrong side of the flapper assembly. Did the check valve come with the unit? If not, you will need to fix it if you can or replace it.
