1988 Force 125hp bogs down at WOT

[21BaylinerCC]

So I finally got my boat out on the water this weekend. The engine started right up and idles fine. Had to adjust the idle screw in order to shift from neutral into gear. Got it out of the marina into open water, gave it WOT, and bogged down after about 8 seconds of running strong. I noticed that when I would run it in WOT and prime the fuel bulb, it would stay running at WOT. Any ideas?
I am thinking it's either carbs or the fuel pump assembly. I already checked the fuel vent to see if it was clogged, the primer bulb had resistance, and it's new gas treated with Quickleen and marine Sta Bil.

If it needs the squeezie to keep running it's probably the fuel pump diaphragm.
Also the inline connections need to be removed as they can suck air and cause your problem.

Fuel pump as Jerry said will be your first suspect.

ok thank you. She's at the marina right now so the mechanics can look her over. I will probably try tackling the fuel pump myself, however. I need to get out on the water!!
