    Thats actually ok ! Smoking like crazy when you start it and run it in the water.. its a 2-stroke! its suppose to smoke.

    it will smoke a lot when starting usually, then calm down to a slight smoke always coming out it. if its not smoking, you have a problem! sounds crazy huh? but its true

    that oil is ok coming out the back.. its used burned gas and oil mix thats coming out pf the big pipe.. mostly 2-stroke oil. your fine there.. it gets like muck because its mixed with water in it.

    Your idle is fine too. when you start it out of the water, the pump and engine dont have a load on it(the water going thru it) and ends up running a higher rpm out of the water.. 2800 is about right.. when its in the water, it should be around 1250-1300 rpms.. so no worries.. your ok.

    if its in the water and running 2800 rpms, theres a tee on the carb rail that you unscrew to lower the idle speed. the screw has a tee and a spring on it.
