I have a 1994 mariner it has set for about 6 months. I have replaced the power pak, the boat idles fine and will rev with no problem but when put in gear it will only rev to 3000 rpm and not plane out. would this be something with the electronics or more likely a carb issue? it will rev to 6000 rpm not in gear, any advice would be appreciated

Don't rev to 6000 RPMs without a load.

You could check for spark.

But it sounds like a fuel problem. Try pumping the primer bulb and if this gets you up on a plane then your fuel pump is shot and needs a rebuild. If not the carbs likely need cleaning.

What's the condition of your fuel, fuel line, and primer bulb.
