How to Keep Your Boat Motor Running

For every boat owner, it’s important to give your boat’s motor a tune-up about once a year. If you are the type that wants your boat to last and has safety as a top concern, this will definitely help. Although these general steps apply to most types of boat motors, it’s a good idea to also consult your boat’s owner’s manual and to familiarize yourself with any specific concerns regarding your boat and your motor. However, for most types of boat motors, here are some simple steps for doing a tune-up on your outboard motor.

Make a point of visually inspecting it. By removing the cowling you will be able to expose the power head. Then, start the motor and examine the bottom part of the unit for any signs of lubricants leaking out. Especially look around the screws that hold the housing. Although it is perfectly natural to see a bit of oil, you need to watch out for stains that go down from the propeller. This is a dangerous sign that there may be a leak that needs your attention. If so, this is something that probably needs a qualified mechanic for outboard motors.

Step 2: Carefully examine the propeller of your boat. Look for any small cracks or hairline fractures in the blades, and check for nicks around the edges. Also, look at the blades from multiple angles to make sure that they’re not bent or out of alignment. If any of these problems have developed, call a propeller specialist.

Step 3: Do a lubricant change. Remove the fill plugs and allow the lubricant to drain into a container. Then, consult your owner’s manual for the recommended type of lubricant, and replace it.

Step 4: Carefully inspect the lower unit, looking for any missing bolts or nuts. Occassionally, you can take a look at the diagrams in your manual. This will help you to make sure that all is in place. Check for any loose screws, bolts, or nuts and tighten them.

Step 5: Lubricate the grease fittings of the transom clamp bracket. Then, using a recommended waterproof grease, lubricate the swivel bracket and the transom clamp screw threads.
