150 Mercury Pro XS

[phatdaddy]

Understand, typical of older carbed mercs. Had an 86 with same issues. Once warm, just look at the key and she would start.

I would keep a new fuel pump in it, that seemed to help.

Also had a sequence

squeeze ball
raise throttle lever half way
hit enricher on key 3 times
slow count to ten
turn key
cross fingers

I'm on my third engine with boat. first one lasted until 94. second one till 2015. six years on this one so far. All merc/mariner 150's.
