My grandparents have always lived in Washington State. Several years ago, they decided that they were going to take their boat up to Canada for a bit. It isn’t a terribly long trip, but it’s a lot rougher water than their boat is usually accustomed to. They have an outboard motor as a backup engine in case their actual engine dies at any point.
For the trip to Canada, they brought along a lot of extra boat maintenance gear. They had several bottles of Mercury outboard oil, just in case they needed it during the journey. They also brought their usual supply of food plus some extra in case they got lost or stuck out somewhere. They managed to travel to Canada and back without too many problems.
