Put he outboard on the back full choke, throttle lever up and down once two pulls and then no choke two pulls and she fires up. Well not this time. Last time I used her was three weeks ago and no problems.

Boat went up for work on it and now o/b wont work. Checked all the wiring, fuel is coming thru also. Just have to change spark plug and if that dont do the trick I am stuck. Fuel is fresh by the wayand engine turns fine but just wont fire.

Now where do I get a spare spark plug in Guernsey on a Sunday?

Right off to Herm for lunch and a swim this afternoon in Shell Bay or Grand Greve, Sark.

Had the same problem - was water in the carb.

Never liked easy start in petrols, fine in diesels, it sends the compression through the roof.
Basic fault finding. You've assertained that fuel is getting through and its fresh. Spark plugs rarely give up these days. So have you got a spark. Hold the body of the plug aginst the block and pull the starter. You should have a nice bright 'blue' spark. If no spark check connections to coil. Is it a CDI system or conventional points.
Is the plug "wet" with petrol after you've tried to start it. The petrol maybe getting through to the carb, but is it getting into the cylinder.

Depsol,

You haven't been putting soltron in the fuel have you?

If it is water in the fuel, why not put some Starbrite Gasoline Stabiliser in, like you promote on another website!

Re: Ditto

First time this year I thought I'd take out the 'flaty so Saturday gave the Mariner 30 5 pulls and started fine (on year-old fuel), ran for 10 minutes no probs.

Excellent I thought, so Sunday am spent 30 mins cramming everything in the back of the estate (and a 30hp and 4.5m flaty are about as big as I can carry!), 10 litres fresh petrol (in with say 2 litres of old) and set up on the beach with 4 guests. Told by two fishermen in smaller flaty it was a bit rough (9am) and they'd let in a few waves. Push off and would it start? Maybe a dozen times in an hour of trying, but longest ran was 60 secs. Cleaned plugs a few times, cleaned fuel filter, checked fuel was coming up from bulb to filter.

Engine done less than 10 hours after full recon (from reputable chap!) so should run perfectly (especially after Saturday's starting). New fuel was 95 octane but old 98 but that shouldn't affect it? Noticed bulb was soft when it did run- should the engine sucking keep the bulb hard? I didn't winterise so maybe carb problem (blasted air from air-horn into carb but I don't suppose that did anything!). Would too much oil cause these probs? I did measure but the new fuel is the only difference over Saturday so it's my main suspect.

Knackering few hours loading, setting up, pulling, packing-up, unloading! And all for nothing with a bored audience.

Bl**dy outboards!
