Essential spares kept onboard?

[Barry20]

I have a 2019 DF70A with 600 hours that I often take 100KM offshore.
What are a list of essential spares that you would take for that motor. If things went bad I do have the ability to call marine rescue but I also want to ability to fix likely issues and get home myself if possible.
I’ve currently carry
spare prop
Fuses
Fuel water separator filters
low pressure fuel filter
jump start pack
cable ties
gorilla tape
hose clamps.
spark plugs
various tools.

Thanks

Thats pretty well it all.

The most likely issues are fuel contamination and battery failure, and you have them covered.

If you were real keen, a spare prop nut and split pins may be worth considering too.

Spare fuel primer bulb ,hose barb to butt splice damaged fuel line.

Thanks for the replies. I do already have a spare prop nut and pins but a primer bulb and fuel hose barb is a good idea that I don’t have yet.
