Hi Folks,I have bought an old 1970 Larson 21' boat with an OMC outdrive.Here is my problem.I want to change the impeller cuz the boat has not been in the water in a few years.I have tried to take the lower unit off to get to the impeller housing but there is a wire harness in there that is making it difficult to get the housing far enough off to get to the impeller housing it self.The boat has a "Shift-Elect" running the motor and outdrive and obviously this harness has something to do with shifting.What do I do to disconnect that wire or get some slack out of it to do this impeller work.Remember,This is an old boat so I don't want to mess with the wiring to much as it is probably brittle. Thanks alot,Dave
