1981 75HP flooding?

[glastronv178]

I have a 1981 75HP evinrude. Have not been taking it our on the water, but each time I start it, it always starts and runs great. Installed new below deck tank, larger fuel lines, filter. Took the boat on the water friday and as usual started and ran great, came home, ran the motor on muffs to flush it, ran great too...
Yesterday, took the boat back on the water, outside temp was above 90 degree (hot for us in washington st.) and the motor would not start. cranking and cranking but not starting...I used the choke as usual, even if the weather was hot, could it have flooded the motor? I kept priming the bulb, and trying to start but after a few minutes, I could smell gas near the motor and it was probably flooded. there were many boats trying to launch, so I put the boat back on the trailer and left. battery is too weak now so I will have to wait to charge it to see if it starts now....Anything I did wrong? so now what?

I read a post about another motor flooding, and something was said about disconnecting the fuel line during storage/transportation to avoid flooding carburators? should I disconnect them?

i think you need to do some trouble shooting. check spark on all 3 and compression. had the motor sat up for a period of time? using new or old fuel? what do your plugs look like? portable or built in tank? if you smell gas, yes it is flooded.

I am at work right now so I will check the plugs tonight.
To answer the questions I can right now:
It is a built in tank (newly installed with new hose, filter....).
New gas+stabil.
The motor was used on friday and ran great with no sign of showing any problems, that is why I was puzzled that it didn't start 2 days later.
since the gas line was hooked up and that we had anormally high temps, I wonder if gas could have flooded the carbs/engine? it is probably a dumb hypothesis, excuse my lack of knowledge about outboards.
Compression and spark were checked over the winter and all 3 cylinders were 110+/-2
I guess I just wonder how you can flood an engine, maybe by choking when it is hot?
