That sounds about right kevin, and consider investing in a hand held VHF.
I know this sounds obvious but I have fallen for this one
, its all very well carrying extra fuel but remember the two stroke oil! Check your autolube reservoir (if relevant) and carry some spare oil, if your outboard is pre-mix it would be best to premix the spare fuel before setting off, I have known someone to connect the spare fuel tank after running the main one dry, but the spare tank had'nt been mixed
Result, one seized engine!
Louise, I have read your extensive kit list, I am surprised Blue Ice planes
Good luck Kevin, Im sure you will enjoy it.
