Do you prime ?

[phatdaddy]

2014 four stroke 150 merc. Just turn key on, listen for the fuel pump to pressurize, turn key, it starts

1994 150 merc 2 stroke, squeeze ball till firm, turn key on, raise throttle advance half way, push key in 3 times, turn key, it starts, usually

My buddy has a 2004 merc O.B 150 and he never primes it doesn't even have a bulb so he says I find that hard to believe, I always prime mine but I'm having a issue she is not getting hard, or firm I will hold it horizontally next time but I don't remember ever doing that before ,.
