This may be a dumb question, but I removed my prop for repairs the other day and noticed water in the cavity just foward of the prop. The outdrive was up in the trailer position last time it rained and I guess water just collected in there and sat. Is there a drain hole for this area? I am asking because this winter I stored my boat in the garage, but next year it will probably be stored outside, and I am concered about it freezing and cracking the lower unit. BTW, most of the marinas around here store thier new boats with the outdrive up all winter, so I don't know how they don't have problems with this.
