probably - relax and carefully work through some very basic things:

[symptom nothing when you turn key]
- is engine in neutral (wont start in gear)
- is the battery isolator on
- is battery dead
- master fuse blown

[turns over but wont start]
- is kill cord connected (faults in the kill cord wiring/switch are also not that uncommon)
- is fuel tank connected, and primed and vent open
- is there water in the fuel

[engine starts but cuts out or "almost starts"]
- is fuel tank vent open
- is there water in the fuel
- could the fuel filters be blocked

Realistially, what Polwart posted along with maybe changing a spark plug in calm weather is the most you'll be able to do while out of port unless you're either very lucky or very good.
If you don't know what you're doing, the time to try to learn is definitely not when you're hanging over the stern 2 miles offshore and you're trying to 'manage' the crew who will inevitably be a tad worried. You'll only worry them more and make yourself seasick if you're susceptible to it.

Also remember if you fall in while trying to fix a dead outboard, no-one can come back for you unless a crew member knows how to use the auxiliary...

If it's happened when you are out, then it's pretty much going to be either a lack of fuel or spark. As Polwart / Nos says, it's usually simple stuff (e.g.is there a diving bottle trapping the fuel line? kind of thing) If you have an EFI then it;s worth also carrying a tin of WD40 or your favourite water dispersing oil)- there wil lbe a few sensors in there - un / re plugging & a squirt with the WD can work wonders...... Likewise if it starts to run roughly, doing that with the injector plugs may cure it.

Occasionally an adjuster screw will shake loose (like my spark advance stop did recently) but generally speaking for "no go" see the above posts!


It's also the reason to have a radio (& know how to use it!) & an Aux.......

The only times I've unexpectedly stopped while on the water have been due to the kill cord (doing what it's supposed to do; can't lean too far over to retrieve water bottles from the deck); a fuel delivery problem (as in "I need someone to deliver some fuel to me"), and a couple of incidents with kelp or plastic wrapping around the leg and blocking cooling water (didn't quit; got alarms and the engine kicked back to safe mode.)

IMO, despite having quite a collection of tools and spares, I doubt that I could or would do any serious troubleshooting on the water. Check fuel, kill cord, battery settings, then call for a tow (preferably from another recreational boater - cheaper than a commercial tow service.)

Ummm, if the motor's dead, where's it going to go?

Actually, having a line on would be a wise idea.

Over the top of the next wave is a hell of a long way to swim fully clothed.

Original post - the outcome

Might be of interest to other novices (like GerryP) to post the outcome to my initial post. I've found a Yamaha engineer ready to come and do a simple first service with the boat still on the water - didnt want to get it out as its only done 29 hours. For 70 labour plus around
40 parts he changes engine oil, inspects but doesnt change gearbox oil, does all other
lubs, spark plug & battery check, & 'sets up' the engine.

i'm going to be there to consult him on the other queries in this thread & find out how to do routine checks myself. Then in October when engine will have done 70 or 80 hours think i'll take boat out for fuller service, winterising, antifoul etc.

Hopefully this plan covers it. Thanks again for the safety advice posted in this thread. Ivan

inspecting gearbox oil with the engine still in the water sounds a bit dodgy to me. There was definitely some signs of fine metal particles in mine at 10 hrs (ish) - IMHO most important part of those early services is the oil change.

i did a first 10 hour oil change yesterday ,and was showing my 9 year old looking under a magnifying glass how much smal particals of metal were in the clean looking oil ,though there was one fairly large bit of machining swarf by the looks ,dont know if manifactures still use running in oil but they always seem smoother with new oil in .
