One thing that get me, Is the kicker engine for safety.Yes it does give you a piece of mind.
But come on lets get real.
How many people have a back up engine in their automobile.
Do you have a spare lawn mower so you know you will get the grass cut.
If engines where that un-reliable. Would you really want a kicker for back up.
The best piece of safety equipment you can have is a VHF radio.
