1977 OMC 190 stringer water pump

[sdvanhook]

My boat over heated and died and had to be towed in. I think the water impeller pump went out after reading other posts. I removed the intake screen and found 2 black rubber pieces laying on the screen. My question is should I get the entire pump assyembly, just the impeller, or impeller service kit without the housing? I found multiple part numbers not sure which one is the right one or if all will work.

And how difficult is it to replace water pump myself? Any special tools required or things I should watch out for? Any Help would be appreciated.

Get the kit with the housing. For the extra few $$ it's worth having as a spare even if you don't need it right now, but if you burnt up the impeller the housing may be cooked too. It's not that hard of a job, no special tools needed unless you're replacing gears. I did mine in about 3hours, not including some time fighting with a couple of broken bolts. Get a seal kit and replace any you can get to while you're at it.
