With the reliability of motors way up, we often forget they can break. Now this is not intended to turn you into a super boat fixer.
However, having some basic tools on board will help you in the even you want to tighten, loosen, replace or stick something. It’s also good if someone else comes on board to help.
So stick to the essentials, pliers, screw driver and wrench, but also add a multi tool which can be very helpful. Then of course duct tape – I know, I’m big into duct tape.
A scissors is another good idea because they always come in handy. The flashlight on your phone is nice, but it’s also great to have a stand alone light (and batteries) – and finally… the biggie, have an extra drain plug with you.
Just like your purse contains essentials for your "survival" your boat needs a purse too! You'll thank yourself for creating it.
