Assortment of Hose clamps and some split hard wall hose to make a temporary patch on a leaking or broken hose.
Volt-ohm meter always good to have to trouble shoot electrical issues
Mask and knife in case something gets wrapped around a prop
On my last gas engine boat I used to carry a spare coil, distributer pickup (mercuiser thunderbolt) and fuel pump, ( I had spares laying around)

Have a great trip.
