Ok...I have had a few problems with my 40hp Johnson 1973..Found the water tube was broken and i have since replaced it, along with stripping the power head down and cleaning all the heads, pistons, water gunnels and even retapped and threaded all the bolt holes and replaced all the gaskets..
I re asembled and startted the motor in lest then 2 turns, It runs beautifully..Just no water comeing through...
So, I once again removed the gear box. Connected a hose directly to the water tube and I have compleate water flow like it should (unlike previously)..I disassembled the NEW water pum and rechecked it all...It all seems good and the impeller is even spinning by hand on the drive shaft...
Is there anything I may have missed as to why its not pumping up to the power head...???? Thanks guys..
