Default 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.

I had a 5.7L I/O, and I always had to 'pump' the throttle two or three
times when starting it cold. I also had to start it with the throttle open
somewhat, 2000 rpm sounds about right. But as soon as it started I'd
throttle down to idle.

I bought the boat when it was two years old, and I sold it when it was
about ten years old, just to give you a frame of reference.

I would let the boat idle for a few seconds before shutting it down.
