Is the engine idling at normal speed? To fast an idle will cause this. If the transmission has its own fluid is it full and clean?

How to remove the lower unit on a Mercury outboard motor ...

go google and type in--- mercury outboard motor manuals --and there are pages of download manuals
if there is not one for your engine then alter the url question to --manual for mercury outboard engine 150hp v6--and see what comes up.

renew spark plugs,mix up some fresh fuel,put choke on,throttle set at just above idle,pump up fuel bulb by hand till tight,put outboard in a water drum,try pulling or turning on starter till it fires,then push choke in and restart

I have a 25 hp merc outboard that starts right up but idles high then low and when running it just dies . Is it a choke problem?

Have your spark plugs changed AND carbs cleaned and adjusted.
Usually that can also be caused by a seized advance system ( plate under the flywheel, commanded to turn with the throttle linkage... )

Could be several reasons for this, poor quality / dirty gas, restricted fuel line either partially blocked or pinched at some point come straight to my mind.

It's possible that a little fuel vapour come out of a carb on an hot engine that has just stopped.
Does the motor starts again and runs well in higher rpm ranges? Is the stall only when idling? If so, enrich the idle fuel mix ( screw out the idle mix screws half a turn t a time )
