Boat Preventive Maintenance

If you've ever been out in the middle of the water when the engine on your boat quits working, you're familiar with that sinking feeling that has nothing to do with your boat taking on water. If you find out later that the problem could have been prevented with proper maintenance, you feel even worse.

Another thing to remember is that in the last few years, 8% of the boats in reported accidents and 4% of all fatalities involved equipment- or maintenance-related factors. In addition, 34% of boating citations were issued because of equipment-related violations. Use the table below to help prevent a disaster, and to maintain the health and longevity of your engine, your boat, and all the equipment on board.

The best place to start with preventive maintenance is to read the recommendations in the manual that came with your boat. If you can't find your manual, then follow the recommendations in this table that apply to your boat.
