I'm going to change the water pump on a 72 Evinrude 50hp hydro-shift unit. As I understand it there is a harness running in the lower housing to the gear case. I'm not certain where I disconnect in the engine cowling area. Also I would appreciate any tips regarding the procedure that might help me avoid disaster. I do have an electonic scan of the appropriate manual which looks like it might be a Clymer but I'm not sure it is comprehensive enough. For example, it doesn't mention disconnecting the shift harness before dropping the lower unit.
PS the local shop estimates $278 to do this job. Sounds rather high to me. What say you?
