I don't think moving up in props from a 30 to a 32 will help him, he is only revving 5100, Merc Racing 525's are set up ideally to spin 5200 and will not bounce off a stock limiter until 5400.
IMO 32's will kill his rpm unless they are worked over a lot.

Just trim that fat girl out until you break loose then down a notch from there....

5100 rpm with trim level 3
I go to trim level 5 more rpm I think up to 5300

I have a 2000 33zx poker run edition with 600's. i am pushing about 1300 hp. I top out at 85-86 mph GPS.
Trim - 5
Rpm - 5200-5300

I have extension boxes so I am sure that changes the situation..

I would have to say trim up more.

Pgatso, you may a prop issue based on those speeds and that power. When my 575sci engines were stock I hit a best of 88mph on GPS with an average of 86-87 (freshwater). I have had some struggles dialing in a prop to keep me over 90, due to some bow and stern movement, but I'm going to have bblades try to lab that out.

My stock 03 33zx with 500 efi's runs 78 on GPS if that helps.
