I didn't mean that to sound like an accusation. I've crossed the Irish Sea at 3 knots and was extremely aware of the risks of prolonged low revs. With a 2 stroke it's a possibility which was why I asked. TBH, while it could be almost anything, it's likely to be one of the "usual suspects". On RIBnet it's difficult to know what the OPs boating/engine experience is and members can be reluctant to mention the obvious stuff for fear of causing offense (or sounding stupid themselves). I'm unconcerned by either possibility as I have lots of practice at doing both

If I pootled up a river for an hours and experienced your issue - faltering engine that stopped and failed to proceed - I'd suspect:
  1. Fuel supply - lack thereof. Check vent, check connectors, check primer bulb, check carb
  2. Spark - fouled spark plugs - check and clean/swap out.
  3. Possible overheat for initial failure - but your motor stills turns over?
  4. What I call "double trouble" - like your plugs were a bit fouled, the motor stopped and you flooded it trying to restart. I've seen people use choke on warm starts!
It will be a lot clearer once you try to run it at home and report back!

Thanks for your advice wilk 👍

Oh sorry, I didn't take it as an accusation...... Just can't admit to excess speed on a public forum... 😀

My three "no-gos" while at sea in the SIB have been:

  1. Fuel line disconnected under way (twice). Failed a mile or so offshore - bit of a scare!
  2. Tank vent not opened - failed a couple of miles from launch site - bit of a scare!
  3. While using SIB as a tender, loaded up with gear (big pile) for return to shore, started O/B and did a lap of the RIB, all good on the mooring so headed back to land (a decent row with a good cross tide) - engine died. Pull - nothing. Hmmm - check fuel connection - no fuel line!! (it's taped to the tank) Look forward for fuel tank - just a big pile of crap and a few scary moments while I dig for the fuel tank...
It's amazing how long a wee engine runs on a carb full of fuel

Thanks for the tips wilk, I will follow your "check list" at the weekend and I'll be posting on here with the cause (hopefully)

At least if you were forced to row you were upstream!!! ;-)

Harder to row from the weir to sandy lane.

Lucky the boat was out, never normally is, just coaching tenders to the oarsmen buzzing everywhere in the flat bottomed aluminium boats. They fly!

Though they probably wouldn't help you if you planed past them 30mins earlier!!!! ;-)

Humber p4vwl..... As you say the current was taking us towards the weir... Would have taken hours at that speed though

The boat that helped us was Cheshire fire and rescue, but the wardens boat wasn't out..... So I saved 20 quid (day license) 😀

The ally boats were out earlier but they had all disappeared.... Too windy for the canoes I suspect

I have just had had a quick look at the engine, it seems that fuel is getting through as engine is flooding after trying to start a few times. Removed spark plugs but can't find a spark on either plug/coil
How likely is it that both ignition coils have malfunctioned simultaneously?
Is it likely to be something more serious (e.g. CDI unit)
