Starting technique 190hp Merc (carb'd)

When I first bought my Bayliner I ran out to the water and started
using it before opening up the engine area. At that time it didn't
occur to me that it was carb'd. My starting technique at the time was
to just hit the starter. About 9 of 10 times it started right up. Then
I realized it was carb'd and I should probably give it some gas.
However, since doing that my starting percentage had dropped. What I'm
doing now is to move the throttle full forward (in idle), then back
full back, and then leave it back enough that it will start around
2000 RPM. Then I hit the starter. However, my "start on first attempt"
is less than when I did nothing.
Just curious how much priming people generally do.
Also, I've noticed that when I'm pulling someone; when I shutdown to
let them in the boat the boat tends to diesel for a bit. This doesn't
happen when I'm not pulling someone in the water. Can someone
recommend a good stopping technique? Should I let it idle for a bit or
should I run it at high RPM (in idle) before shutting down?
BTW: Where I am outside temps are between 90F-110F so I"m not sure if
"cold start" is the right term.

Do what works best.
I would be a little concerned about the run on. Idling for a while will
make it shut down more positively when you turn it off. But the run on also
indicates that you may have detonation. That is the gas being prematurely
ignited because of heat in the cylinder. That is bad for the engine. Make
sure your cooling system is performing properly. When was the last time you
replaced the impeller? If you are using regular gas I suggest you try a
couple tanks of premium and see if that reduces it. Detonation or
pre-ignition can result in melted pistons/damaged cylinders so it's not
something you want to completely ignore.
