I am stumped and have a problem to post to the iboat gurus. I have a 1968 mercury 500 thunderbolt 50 hp outboard. I replaced the impeller yesterday and it still won't pump water. I know i did it right, fins turned propper direction, key in place, the cup and rest of the water pump cover is in good shape and I snugged it back together good.....I started it and no flow from the pee hole I only let it run about 20 seconds on muffs for fear of overheating. was that long enough? I cleared some crap out of the rubber hose to the pee hole and actually took it off and put it back onto make sure it was clear.
1. is it possible that the copper hose connected to the top section of the water pump cover is clogged. And if i take it apart to check this will i have to replace the seals in the water pump since i just put them in yesterday?
2. If not the copper water tube what else could be plugged up and how do i get to it to clear it out?
3. I connected the muffs over the four small holes just above the propeller on the lower leg of the motor, is this the proper place to put them or does anybody have a picture of the right place to put the muffs?
P.S the old impeller came out whole no chunks of rubber missing to clog up the system.
Any help would be appreciated,
Shane
