Mariner 60 Slow Starting

Hi
I have a Mariner 60 hp 2 stroke ( year 96 ) which is slow at starting from cold . It takes about 40 to 60 seconds of turning before it starts . Once started ( even for a couple of seconds ) it will restart at the first turn of the key and run perfect all day long . I think I am doing everything correct in starting from cold . I can start a Yamaha 85 hp second or third turn of the key on a different rib from cold every time .
The outboard was serviced two years ago but only has about 20 hours done since so I suspect that everything should be ok .

Any ideas ?.

Thanks

First thought would be to check the chokes are working by taking the air box off the front of the carbs and pressing the key in.

Thanks for that . I had some work done on the Quicksilver Controller a while back so maybe the choke wasn't connected back correctily although it was never that quick to start from cold from the beginning . Do you usually hold the choke in while trying to start it or just push it in a couple of times , release it and then try to start ?.

Hold it in while you turn....

An even easier way than how Pete describes is just to listen; you should here a click (from the engine that is) when you press the key in.

I will check out for the "click" this evening . I have a feeling that its not there
so that could be the source of my problem .

Do as the others have said, but to add to that its not just the number of hours the engine has done its also how long thats why it will say just as an example 100hrs or 1 year

Check your primer bulb is ok as well-it'll take a long time to start from cold if the engine has to fill the lines 1st.

Hi All

Thanks for all your suggestions . I checked for the click and its there .
I havn't gone as far as taking off the air filter to see if the choke is functioning but I will have a look over the weekend . It could be the
primer bulb as the engine makes no attempt to start for the first minute
but once it fires it starts and runs fine afterwards . I have an in-line filter between the outboard and the primer bulb , could this cause a problem ?.
Anyone any idea what the sparkplug gap is set to on the Mariner 60's ?. No harm in changing them while I am at it .

Regards

Tim

Given that it hasn't been serviced for a while why not change the plugs.....
