I had an '02 Jag with a 225 Optimax, best prop for me was a 24 3 blade Fury, no plugs, I bet that a 4 blade Fury 24 would run well too.
are you hitting 3500-3800 rpms on take off? if not you need more venting

Check the Mercury boards. Those motors can suffer from clogged up exhaust tuner relief holes and cause the symptoms you are having.

We did use 25 Predator Eagle propellers on this age product and a 24 or 25 Fury may work well today. This was pre Fury and pre-Trophy also, and a. 25 or 24 Trophy could work with an exhaust vent ring.
This engine is prone to the TPI moving and it may need adjusting by a competent technician, which only takes a few minutes. Fuel supply could also be an issue as this Mercury Marine fuel line (grey) is not an ethanol resistant and deteriorates internally. The boats lines are ethanol resistant. From memory spark plugs also could be needed but we don’t recall their number we used.
What was hull weight on the old jags?
Thanks everyone. Will look at all suggestions. I do have a Trophy Plus 24 4 blade with the exhaust ring I am going to try first. Will update when know more
My 99 Jag belonged to Governor Mike Huckabee and I have the build sheet that came with it. It has a 225 Opti and came from the factory with a 23 Tempest Plus. The hole shot is great.

Try it with and without the exhaust ring.
I remember those Predator Props when I ran a PII back in the day. It did love that prop. It finally slung a blade, and I couldn’t find another, and it was hard to find one that would work. I remember having issues as you are having, we finally solved it, but don’t remember how. I dearly loved that rig, it was a screamer, and great to fish out of. One of my all time favorites.
