I finished complete rebuild of powerhead, replaced water pump,rebuilt carbs & replaced gas lines, and put all back together. It runs great but the tell tale stream gets weaker and hotter the longer it runs. One time to the point I couldn't hold my hand in the stream. I immediately shut it down. I removed lower unit and thermostat cover and checked water pump install , ran hose up water tube and back down with good flow (I think I had poppets in backwards- long side to spring). Figuring I was good I started it again ( on muffs) the stream started out a lot stronger then slowly weakened again. There was a lot of water coming out where mid section mounts to the pivot just above cavitation plate and a stream to the front where lower and mid connect. Also exhaust is coming from the holes at the rear of lower unit just above the cavitation plate . From the diagrams in the manual it looks like water should be exiting there. Any suggestions?
