'05 320 running rich and smoking - starboard motor ??? pls advise

[ipxih]

Hi,

changed new fuel module and had my injectors on starboard motor redone with all acurate readings. fired up the boat and not it appears to smoke from exhaust on idle and certainly noticed a double fuel burn vs. port side motor.

i took her out thinking it needed some old fuel burned, and went for a 3hr cruise this evening;

topped off both motors with premium gas and port motor reads now 88% , starboard motor reads 47%

i can certainly see smoke out of starboard exhaust pipe while cruising and was hoping its just old fuel burn off but its not going away.

the good news is boat runs smooth and idles steady.

no misfires or hesitation.

Any advise what to look for and begin the diagnostic ?

new spark plugs
new Exhaust manifolds
new belts
new oils
new fuel module and pump assembly
new fuel filters

any suggestions ?


thanks

What color smoke? Pull a couple of plugs and post up a good pic.

I'm having the same issue. It used to be just at start up, then went away. Now it seems to be consistently a small amount of white smoke. Going to start with oil changes & plugs, then check back in...
