Starting Outboard after long winter.

Hey all, as most of you know , I purchased a 2004 Yamaha VMax 150 last
winter. Well, I am moving into season # 2, and I have done all the
things the marina suggested with filling the gear case lube, checked the
spark plugs for blackness, draining the fuel line to the motor, I
actually emptied the old fuel out of my tanks (equated to about a
quarter of one of my tanks, so there wasn't much left) and charged my
batteries. My motor is carbureted, so I was wondering if there is
anything I can do to help me start the motor the first time. I will
probably be in the low 40's tomorrow morning when I put her in the water
for the first time this year!

I appreciate any info you guys could throw at me :-)
