1700 hours on a 2004 df250 4 stroke that has never left me stranded. Put your money in a towboat us or seatow policy and a sat phone. They will come to you if by some remote chance you have an issue. The policies are cheap because their risk is low.
You also have to consider the statistical likelihood you will have a failure very far offshore. Set aside the chances are very low for any failure to consider your best chance for a failure at your furthest destination is at 30% of that. If you're taking your 20 footer 50+ miles offshore you are way more likely to have an environmental problem than a mechanical one.
For those who enjoy the security of additional kicker engines, I have a nice honda 8 hp in long shaft perfect for the job. It will never end up back on my rig again so it is available for any interested.
