I cant find a lower unit gasket kit for my 1977 70hp johnson. I really need to take the unit apart so i can replace the impeller and change fluid. Any advice?
The only gaskets needed are for the water pump and new seals for the fill/drain plugs. Lower unit parts diagram here on iboats - http://www.iboats.com/Gearcase-15-T...895223--**********.348579478--view_id.1533173
The fill/drain seals are item # 46, OEM PN 0311598. But several sets so you have them on hand for later lube checking and changing.
Sierra water pump kit is here - http://www.iboats.com/mall/partfind...gd_poid=110966&gd_row=45&**********=348579478
