Mercury 75 EFI 4 Stroke 2009

[dwright17]

Have a 2009 75 hp with < than 25 hours. Motor has good fuel pressure and good compression. Has a dead miss on # 3 cylinder. Has good spark plug and coil and good fuel injector. Any ideas what else could cause the miss? When cold, the engine runs fine for 60 secs or so. Thanks,

Does that matter ?

Is it still under the 5 year warrantee ? Have you had it on a mercury diagnostic computer? Any saved errors ?

Yes it does. I need to be able to look at the right model.

Yep, since the start like 150 or so.

150 variants of the Mercury 75 EFI 4 Stroke 2009 is hard to believe. !
