A good tool kit will have a range of screwdrivers, a full set of open-end wrenches, several pliers (needlenose, slip-joint and locking), socket wrenches with handles of varying lengths and Allen wrenches. To this, I’d add a hacksaw and several blades (great for sawing a tangled rope off the prop) and a Swiss Army knife. I like having a voltmeter for checking on electrical shorts, and a file can fix that sharp corner after you’ve cut yourself on it. I make sure everything is quality, too. Don’t even think about going to buy the all-in-one tool kit from Wal-Mart. Take the time to walk around your boat and identify areas that may need servicing, and ask yourself if you have the right tools on board to do the job right, and with ease.
