Thinking that a cleaver or a Ballistic (mild bow lift and thin blades) might be a good prop to try.

There are two SST props from OMC, but they tested about the same MPH on my boat.

Very cool Joe. Oughta really scoot with just the driver & a light load. I member the 153 was very sensitive to any additional weight.

David might be on to something with his cleaver suggestion.

Fwiw so long as your hi-temp alarm(s) work? I wouldn't rush out & buy a pressure gauge. You still have plenty of room to go up before you run into any issues.
