Hey all.
So I have recently acquired a Johnson 4hp 1996 outboard. When I first took it out it would run but got bogged down and died and I couldnt restart it. I serviced the carb and found a lot of crap in the fuel filter, so i replaced the fuel filter and cleaned the jets in the carb. The second time i took it out the tell tale stopped pumping water out of it which cut my trip again. I decided that i would fit a new water pump and changed the gear lube while I was doing it. I just took the engine out again and it will run half throttle no problem but when I open her up it will run for about a min but then bog down and almost stop. The water coming out of the engine is pretty warm but not hot. I am now thinking could it be overheating somehow? Any ideas before I take off the head and check all the water channels are clear? Btw while I had the gearbox off I did put a hose onto the water intake and water came out fine. Its beginning to get frustrating
