Well the problem has been fixed. I changed the shims and that fixed 75% of the issue. The next day I went out and cleaned the bottom. There was a small build up, no more than I have had in the past and there were a few small barnacles
on the prop. After cleaning
everything we are back in business. Water
is crystal clear all the way up to 3400rpm and barley visible smoke is consistent all the way threw the RPM range.
I do think I am slightly over propped, I can only get 3400rpm wide open but I am not concerned being that there are signs that the engine is being over worked and there never has in the past. I am at my haul speed at 2700rpm for a strong cruise
I can definitely tell the injectors were stuck, I could not here them before but now the sound is distinct and very recognizable, in all the motor
is smoother and quieter then ever.
Thank You everyone for your help and input.
