Boat has been running fine all summer. Went speck fishing Sunday and ran 6 miles to get to fishing grounds no problems. Left to go to beach running @ 4500 RPM and motor died like it run out of gas. Hard to crank back up but then would not get on plane without going dead. Would run at 1200 RPM for a few minutes then die. Pump primer bulb to fill Fuel/Water separator on engine, hard to crank, would run at ~1200 RPM for a few minutes then die. Did this all the way back to boat ramp.. Pumped primer bulb today in driveway and raw fuel coming out of exhaust at prop. Hole in LP pump?

Just replaced my LP pumps on my 200 ox66. My symptoms were different. Mine would barely idle, had raw fuel coming from exaust, when I pumped the bulb it would die. I had a ruptured diaphram in one of mine. Easy way to test, unbolt the pumps from the block and have someone pump the primer bulb. If you get any fuel coming out behind the pump it is bad. Once you pull them you can open them up to get a look at the diaphram.

I would replace them both if you haven't in several years. Should be done every 3 to 4 years anyway.

Some times life is simple and you find your problems quickly.
Hope you replace them all
