After the egg take open up that damn gate and let the rest of the salmon coming go do there natural spawning. It's pure cruelty to see them fish struggling to get past that gate. They what to get to where they were born !!!!!! A little more natural reproduction can't hurt.
I'm sorry. but whole conversation has been a blast. But I must have been talking about the wrong pee hole ! And by the way milkyman the impeller speeds up and slows down with engine RPM.!!! Its running off frickin drive shaft!!!and that time it takes to start peein. is the t-stat opening!!!! all 6 of my outboards work that. Mine are all big 2-strokes even honda 8.8 kicker 4 stroke . Maybe different for new 4 stokes don't know don't have one don't care either. How did I come to this conclusion? mud bugs plugged up both T-Stats started motor no pee. Took apart both t-stats cleaned water channels and housings. put back together no it pees aaaaaaaahhhhhh
I once had an old evenrude V-4 that had same problem .Would get hot after 10 mins. Did all the stuff mentioned in this topic. Damn thing still got hot . Final pulled heads and found cylinders scored . Lots of friction makes lots of heat even when properly functioning. Motor still ran too. Hope that is not your problem.. I junked it.POS. Probably happened when impeller was damaged and we ran it to long trying to catch one more frickin fish. Ha
