New Mariner 6hp 4 stroke won't start

[Revorik]

Hi, just bought a new Mariner 6hp (ex display) and I can't get it to start and had no manual and can't find one online.

It's one of these; Mariner F6 MH - 6hp short shaft outboard from Marine Tech

Most likely I'm missing something daft here, but has new fuel, switch down to select internal tank, kill cord fitted, throttle in start position and tried various choke positions. No sign of life, and doesn't seem to have an on/ff electrical switch or priming bulb?

Any ideas, and if anyone has a link to a manual would be brilliant. Cheers.

Take it back!

Yes will ring them tomorrow, just wanted to make sure I wasn't missing something, and can't find the manual.

Is the HT lead firmly on the spark plug?

Has it got oil in it

If you have a spark plug wrench, you could remove the spark plug and take a look: check the gap, spray / clean the plug with contact cleaner, allow things to dry (spark plug out) for a couple of hours and try again.

That won’t stop it from starting, or at least not the first time. It just won’t run for long.

You don't mention having it in neutral?

You can’t pull the start cord if it’s not in neutral - it locks, or at least, it should lock.

Tank vent open? If has sat for a while with fuel, take out float chamber drain screw, spay carb cleaner in the hole. Tohatsu engines are very reliable and easy to fix.

Doh! I have the tohatsu version of this very engine and I'd completely forgotten that.

Mine doesn't like starting cold much either - I think for emissions they have the idle jet adjusted very low from factory. It hasn't annoyed me enough yet to mess about with it but it's on the list.

May of been returned by another customer as they couldnt get it going either,hence the ex display.

Wouldn't make sense for the retailer to do that. They'd know it would be straight back to them again.

Mine is a pig to start on the internal tank but I run it from a remote tank which is not a problem. They have an automatic decompressor which means it has no 'feel' when turning it over. If you have to run it from the internal tank make sure it is full. Otherwise try a squirt of easy start. If that doesn't work speak to Marine Tech, they are very helpful.

Thank you for all the replies. Took it back after this and the engineer started it up and thought I hadn't released the cap breather enough. I had done that and even took the whole cap off with no joy, but it started so took away again. Had one short trip out ok, just had second and it started to get lumpy later on, would only idle with choke half out when hot, stalled while full throttle and wouldn't start again. Luckily on the river by then (2ish hours running) and had a tow back. Two others tried to start then it did run but left it with the engineer. They recon the carb had oil in it, ready to pickup. It's new, stored either upright or on the handle, why would the carb have oil in it? If oil can seeped in while stored (I did store correctly), surely once running would have burnt it off?

Unlikely to be oil, but could be waxIng from old petrol?

Petrol was Super E5 from Texaco, topped up from a new container mid journey with petrol which had been in there around 3 weeks. I will ask about waxing.
