Cobra Cat propeller pitch

barren

New member
My new (used) Cobra 525 has 2 x 90 hp 4 stroke Suzuki motors on. Took the boat to Harties this weekend for a first test. Lots of revs and it ran into the rev limiter quite quickly. Checked and she’s running 15 pitch 3 blade props.
Is there anyone out there that has a simmilar rig that can give me some idea what the correct pitch props would be for the rig? She’ll be used in Mozambique and will be surf launched.
Any ideas?
