I've noticed that if i give the grease
pump into the stern gland a few pumps when ive finished with the
engine for a few days, i dont get
water in the shaft
bilge. Ive always been a bit hazy about how to use the
pump, sometimes i give it a few pumps if the
engine has been running continuously for a few hours. Anyone able to explain to me exactly what its designed to be used for and whether im gonna do any harm using it the way i have been?
