Try the Yamaha 3 blade T-1 24″ inch pitch, Yamaha did a test with the SHO 225 on a Caracal, the prop turns 5800 and speed is 70-72 depending on setup, I have a 2018 Caracal with the SHO and that’s how I am running. You can get the test from Yamaha’s website. Note: the Caracal is not a speed demon, it takes a long time to get to 70+, trim and jack plate setting are important. Where the Caracal shine’s is its ride especially in big water. Hope this helps.
