I have a 1973 carravelle with a 115hp 1973 evinrude, can anyone tell me how to replace the water pump impeller? i took the 4-5 bolts outa the lower unit but i still cant get the lower unit off.
The '73 is an electric shift, right? If so, there's some tricks of the trade you need to apply while taking the LU off. I've only read about them (haven't done them), but one includes tying a string to the shift wires as you pull the LU off so you can run them back through later.
I'm sure someone will chime in with all the goodies momentarily.
I generally consider that whole '72-'78 period the "re-engineer era" for just about everything OMC. You gotta check and double-check all the cross-year interchangeability or hilarity may ensue.
