    My 30hp sea pro is very cold natured apparently. Using both eStart or pull start, it takes forever for it to fire. Theres no choke on it, or atleast I havent found it yet. I can usually start to tell when its going to fire up after several attempts because the prop starts to creep around. But 90% of the attempts it doesnt move.

    Any tips for getting this thing to fire sooner on cold mornings like today?

    Fuel injected or carbs? Not familiar enough to know off the top of my head. If it has carbs, my years of working on dozens of carbs leads me to believe your pilot (idle) circuit may be getting clogged. That or it is set too lean if it has always been cold natured.

    Does it have a knob on the front of the motor?

    It has carbs.

    This isnt my motor, but an identical one. Heres the front of it:

    you could pop the cowl and manually choke it. PITA but itll get it going quick.

    You either have a problem with the enrichener system or you aren't using it. The black button to the left of the starter handle is a primer bulb. (which is why there is no traditional choke lever) It injects fuel into the motor for quick cold starts. I've only worked on 3 or 4 of that model and some had a decal with cold start procedures on the cowl and some didn't. I see that yours does not. If you are using the primer bulb with the hard starts, it's probably time to have the carb cleaned and adjusted.

    On my Yamaha, I put it in gear twist the throttle about half a dozen times before I try to start it. This will pump some fuel In the carbs and it typically fires right up.

    Push the primer buld by the handle 3 to 5 times then try to start it.

    I'll tell you what's wrong with it, it's a mercury...I fixed the problem by getting rid of it.

    Isn't that a primer bulb by the pull start?
