Shop rag, nitrile gloves, Basic screwdrivers, needle nose pliers, new sparkplugs, Plug wrench, Zip Ties, small length of electrical wire, electrical tape, a few combo wrenches, Rope, and at least $10. (it's a token offering if I need help)
In the boat... I have a full set of basic tools, including a multi-meter, extra fuel filter (spin-on) and an extra CDI/coil pack.
