hello all i was running my motor in the trashcan(clean) an the exaust water stoped comming out. i took apart the lower unit today but the impeller looked good. before puting it bact together i thought i would hook up a derect water line to the tube above the water pump. i did that and under presure water comes out the pee hole but not the exaust port. my question is is there a thermustate on this moter, it's a 60hp johnson 2 cylender. also the water comming out the pee hole was hot also the head was hot to the touch. i shut it off before it got hot, HELP PLEASE!
