RPM Question
I recently bought a Daytona 26, with 525, xr sportmaster, standoff box, and labbed 30p prop. I can only turn between 4800-4900 rpm. Does this rpm sound a little low to you experts out there? Anyone else with a similar set up running higher rpms?

Mercury Racing says 4800-5200, so you are in the range. When the weather gets cooler the RPM will go up so if you were close to the rev limiter now you would be all over it in the cooler weather.
In reading the boat tests they are running them at 5400, so I guess go and try a 28 pitch prop. That will give you 300 more RPM, and see what it will do to your top end. You will then find if you like the 30 or new prop better.
I am no expert.

On your boat a couple of hundred RPM higher could add a coupe more MPH !
However a 30p labbed sounds about right
Are your RPM readings at max trim for performance ( not too high , not too deep ?)

I have the exact set up and will run up to about 5300 rpm. A stock 28 is about perfect. A labbed 28 is all over the limiter.
