Location: Sun Prairie, WI | This is what ive heard and what I do. I was told to not fill the bearing buddies all the way up. This leaves room for the grease to expand when hot and also it allows the grease to contract when backed into the water. Since the bearing buddies are spring loaded when it cools the spring simply moves with the cooling grease not allowing water to get sucked in. Ive done this for the past 6 years on my boat and never a problem. Ive just knocked the bearing buddies off every year just to adjust the bearing preload. Never repacked them. My $.02
