I have acquired a 7.5 Sears Gamefisher Trolling motor Model # 217.585932 and S/N 08-196400. Sears couldn,t tell me excactly what year it was. The parts list they gave me was printed in Feb. 1980. Can any one give a actual date of manufacture. I also would like to know if anyone has an engine cover P/N 110577 and the gear housing cap ( The one on the lower unit with the fin) Are the water pump parts still available?
