Iam going to put a new water pump in my 82, 50hp Johnson, I have a Selco Manual. My Motor has<br />a shift rod. In the book on page 8-173 Lower unit<br />service, it say to remover the starter motor, I don't see what the starter moter has to do with taking the lower unit out? Also I took out the oil screw out of the lower unit, and about three onces of water came out. I am new at this. Do you think that I can do this job? Thanks for any help. Conrad
