Testing the engine at home the other day with the garden hose connected to the motor and water turned on when the alarm went off. Noticed no water coming out the pee hole. Removed the lower unit, impeller looked OK, replaced it anyway. Now, still no water coming out. I do get a good stream of water coming out of the hole where the garden hose connects would connect (lower unit is immersed in a deep bucket of water), but not the pee hole directly below it. Could it be the thermostat? How do I check, or replace.<br /><br />Thanks
