None of that information really helps us.
thr 3.0 and the 120 are 2 different engines, similar, but different.
It also doesn't matter when you bought it, we need to know what year it is, and the year and make of boat doesn't help either. Well, maybe the year helps a little bit, but that is the year of the boat, not when you bought it.
Do you have the engines Mercruiser serial number? It's on a tag just above and slightly aft of the starter.

Sounds like bad gas and carb issues to me.

And check the fuel filter... it could be clogged with gunk from old gas.

Re: Help

The word HELP in the title doesn't really help out either.

Scroll down to all the threads in the forum. Every one is asking for help. This is 4th of July weekend.... So The actual issue in the question is much better than help, cause some might just skip over your issue.

Just sayin..

and... Welcome aboard...

Re: Yizer....help!!!

octane booster won't help with old gas.

Stabil put in the tank before the gas gets old will.......

Re: Help

pull #1 spark plug wire, insert philips screwdriver into end of wire and hold metal part of screwdriver close to ground. have someone turn over engine and you should see spark jumping from screwdriver to ground. if not you have point problem. if you have spark, put plug wire back onto spark plug, disconnect fuel line from carb. put fuel line into container and have someone turn over engine again to see if your getting fuel. if no fuel, pump problem.
