My motor pees good and the tell tale is luke-warm when idling. After a cruise, the pee stream is steaming hot. I can't put my hand under it. The block is pretty hot, too. I also noticed that after the run the exhaust relief had a lot of smoke coming out of it. But after a couple of seconds, it goes back to normal. The motor doesn't run inconsistently or anything. It runs great. Is this normal for a late 90s Merc 25 2 stroke? Keep in mind I just had a complete water pump job done...housing and all.
