Boat And Trailer Maintenance Checklist

Take care of the boat, trailer, and engine and the chances of a problem occurring on the water or the road will be minimized. Here's what you need to know and when to do it.

Fishing boat on Lake Cumberland

So you're a new-boat owner. Your new center-console sits proudly in your driveway, the outboard shining brightly in the sun, and even the trailer is sleek and polished. How can you keep it at least close to looking and performing as it does now, fresh from the dealership? Maintenance is the key. A well-maintained and cared-for boat will always perform better than a neglected one.

But if you're not mechanically inclined, how can you properly care for your new rig? If you're all thumbs, budget in some bucks for dealer maintenance. In this case, it's probably best for both you and your boat if you leave the mechanical details to the pros. You can, however, perform all the tasks that don't require technical expertise. Such tasks as keeping fittings and moving parts lubricated, cleaning and waxing the finish, checking the drive lubricant and engine oil, making sure that fishing line isn't wrapped around the prop shaft — these are all examples of simple skills a responsible boater should learn, especially to protect his or her investment. While boats have never been cheap, they seem to be more expensive than ever when compared to the average paycheck, so it's smart ownership to make sure that all is up to snuff.

Trailer safety chain

Always ensure trailer safety chains are properly connected to the tow vehicle every time you hit the road.

Drain plug

It's a great idea to remove the drain plug when laying up the boat. Just don't forget to replace it before launching.

To help you out, we've created a simple Timeline and Maintenance Chart, one that works for DIYers and tech-savvy boaters alike. Refer to the chart to check maintenance items before every outing and at every 20, 50, and 100 hours of use. Seasonal boaters should consult the chart before every layup. With our chart as your guide, your rig will stay like new for longer and command top price at resale or trade-in time.
