Smoke in idle and self-ignition when turned off 2008 / 4.3 TKS

Hi, I'm new in the forum.

I have an '08 4.3l Mercruiser with the TKS carb and 65 hours from new (in a Bayliner Capri 1850). It start and run fine, but when it is in idle (cold or warm) you can see and smell lot of smoke, that looks like to be rich, but after use it self-ignition when I turned off (that looks like to be poor) The temperature and oil pressure is always ok, even skiing.
The other think is when it warms is little bit more difficult to get it started than cold.

Thanked in advance for your help.

The TKS part of the carb is flooding gas into the engine, repair it.
 
Hi, I'm also interested in learning more about fixing this specific problem.

A friend of mine recently started complaining how his boat (similar model), started experiencing smokes coming out when in idle mode.

He hasn't checked of the temperature and oil pressure, but they are probably ok.

Solutions or thoughts?
