It is four in the morning on the Tyne. A lone skipper takes his 5.5-meter rigid inflatable out past the piers in a stiff wind. Hours later he is four miles offshore, the boat filling with water, the main outboard dead, the auxiliary dead behind it, and a marine VHF he cannot use because the battery is flat. He reaches the coastguard on a dying mobile phone. When the Tynemouth RNLI crew pull him aboard, he tells them he thought he was finished.
He survived because volunteers found him in time. But every link in that chain was avoidable, and the chain started breaking in the first ten minutes after the engine quit. Here is how to use those minutes.
Minute 0–2: keep her safe, not her speed
The instant propulsion goes, your boat stops being a vehicle and becomes a drifting object. Before you touch the engine, make the boat safe: get the bow into the wind and sea so you are not taken beam-on, and tell your crew to put on life jackets. If you are being set toward danger — a lee shore, a wind farm, shipping — get the anchor ready now, while you still have the deck and the daylight to do it calmly.
Minute 2–6: the fast troubleshooting tree
Most outboard failures at sea are mundane and fixable. Work the obvious causes in order, not in panic:
- Kill-cord / lanyard — dislodged more often than anyone admits. Check it first.
- Fuel — tank level, vent open, primer bulb firm, fuel cock on, no kink in the line.
- Water in the fuel — the single most common cause RNLI crews find when they drain a stalled outboard's filter. A clogged or watered filter chokes the engine within minutes.
- Air and spark — overheating alarm? Cooling tell-tale flowing? Connections tight?
If the auxiliary is your backup, it is only a backup if it is fueled, mounted and tested before you leave. In the Tyne case the emergency engine made little headway in the wind and then failed too — a second engine that has never been run hard is a second point of failure, not a safety net.

This is the decision that defines the day. A handheld or fixed VHF on Channel 16 — or a DSC distress alert at the press of a guarded button — reaches the coastguard and every ship around you at once, with your position. A mobile phone reaches one person, depends on cell coverage you may not have offshore, and dies with its battery. If there is any doubt, make the call early, on VHF, before the battery and the light go. Downgrading a Mayday is easy; upgrading a silent drift is not.
Anchor early, conserve battery, show or sound a signal, and keep someone bailing. The order is always the same: boat safe, people safe, call for help, then fix the problem — never the reverse.
The ten minutes you really want are the ones at the dock
The offshore drama is the symptom. The cure is a maintained engine, a fuel system free of water, a tested auxiliary, a charged radio battery on its own circuit, and a pre-departure check that catches all of it before the lines come off. That is dull work. It is also the difference between a story you tell at the bar and a Mayday you hope someone hears.
