Skiff tools- what do you carry?

Hi guys, I'm trying to assemble a small toolkit for on the water emergencies and breakdowns. I am not gifted mechanically, but can do some minor tweaking and wondered what you guys carry onboard. I have a Yami F70, so if there is anything specific to that engine please let me know. My thoughts are a couple of Phillips head screwdrivers of diff lengths and sizes, an adjustable wrench, some 5, 10, and 20amp fuses, tie straps, and duct tape. I prefer to keep it small as I know my limits. Thanks for any help and advice!
