Man,,,wish i can help. My GDSD turned the same prop as the 35 but had a higher reduction....

Go run it,,,the mods may make enough power to pull the 3 blade if the boat is small/light enough...

If not, get the pullies he puts on the 23 with the 3 blade and just let her turn higher. Im sure the 23 is safe up to 4800 or so..
