stalls/stops when accelerating

[rodbolt17]

typically takes me about 3-4 hours to do that motor.
typically your going to need 100 bucks or so worth of parts,unless you buy the kits. kits are close to 100 bucks eachx4.
then I use a 750 dollar manometer to resync them.
then the fuel pump diaphtram is about 50 bucks. takes about 15 min to rebuild it.

00' f100 tlry update

Had all 4 carbs cleaned, mechanic said didn't need new kits. Engine runs 100% better except for slight hesitation at one point. Hesitation/struggle happens at point right before planing but once you increase throttle a little the engine smooths out. Mechanic didn't use manometer, a little disappointed about that.
My Tach gauge is broken so can't tell you RPM but I just bought new one to install today.
Bought gauge from boats.net 6Y5-8350T-83-00 TACHOMETER ASSY to replace existing. Its suppose to be newer model but came with no documentation.
I have some questions about gauge, should I start new thread.
THANKS FOR ALL COMMENTS.

Run a Heavy dose of Yamaha's Ringfree thru the engine. It may very well get rid of that hesitation. It works extremly well and unless the sync is off a bunch, will likely get rid of that hesitation. The more you run it, the better.

Thanks TownsendsFJR1300, I will use Ringfree.

LATE UPDATE
Had carbs cleaned, replaced water pump impeller. Also changed motor oil, dirty but no water. Runs 100% better.

After using motor only 5 times, there is now water in oil !!!

I've created new post in hopes y'all can lead the blind to locate how/where water gets into oil. THANKS
