Just bought my first outboard and another for spares.They are 1976 35hp 35el76g.Neither outboard has been started for years.My question is that I purchased 2 brp new water pumps and each came with 2 gaskets.No where in the manual or in the literature do they mention them. Should I use them or install without.There was also a small piece of curved plastic in each kit and I dont know what they are for.Can anybody help, ive waited 65years for my own boat and want to go fishing.
