My outboard won't start

[Stevie J]

Washed RIb, did all the little jobs i'd promised to do over the winter, recovered the seats, fited that wee bilge pump I bought last summer, all sorted!

Saved the best for last!

Fresh fuel, all primed, turned key!

Starter kicked in, over and over and over.

No life!

Nothing that sounds like a spark!

Now battery pretty flat and starter red hot!

Mariner 90hp

Any thoughts guys?

[neilda]

Have you had a look at the spark plugs?

[Stevie J]

Pulled then HT leads off, cleaned them.

Unscrewed the plugs, cleaned them.

Put it all back together.

No change!

[Stevie J]

Heading out for the night.

Back on all day tomorrow!

Cheers

Killswitch contact?
In-gear interlock?

Is it sparking?

[phillnjack]

Is the fuel tank vent open ? go check it again, ive spent hours only to find it such
a simple mistake. ( but didnt tell her indoors or she would laugh too much)

Is there any fuel at the engine end ? if not mght be trapped air in fuel line.

Did you oil up the pistons went to last pout it away to save corrosion ?

Was the carb empty when last used ? could be well full of varnish if not.
Nowdays petrol starts to go funny after just 6 weeks if left standing still !!!

does that not disengage the starter rather than short the spark? i.e. it won't turnover

Slow down. Start with the basics.

Sparks, fuel, compression.

[Stevie J]

Wil go through the basics again.

Assume to check for a spark I neet to remove a plug, reattach the HT lead and hold the business end against the head!?

Kill switch in place.

Will check the vent isn't stuck shut on tank.

Hand cranked fly wheel a half dozen times to ensure there was fuel/oil around the head before starting, no seize issues, turning fine.

Not sure how i check to see if their is old fuel still in the system!

At least it is a lovely day here is Scotia!

Firth of Forth is like a mill pond!

Need to get out there!!!!!
