2000' Scarab Sport. 2005 300hp Yamaha HPDI's. Just replaced my 3 blades with new set of 3-blades. Breaking in new lower unit so have not pushed the sticks down.

On old props, used to get low 60MPH range. Recently, was mid-upper 50MPH range.

Receipt for new props shows 14-5/8(L&R)23 SS Thunderbolt. Appears to be the stock prop size for the 300 HPDIs.

Didn't experiment with different props due to time constraints (needing to get boat ready for a vacation trip last week that rain canceled anyway.) However, open to hearing what others are doing and will try other props for more top end. Will get out this weekend and see what top end speed and RPMs are.

I have the reverse radar arch with canopy and electronic box. Big wind resistence.

I'm game for trying demo props from one of the OSO sponsors if any of you have a successful recommendation of 4 blade props.

If we are doing 60 -61 MPH with twin 225's on a straight bottom, I would think maybe a stepped hull with 250's has got to be close to 70 MPH... No ??
I know its not the same dynamic but the twin step 38 Top Gun picks up 10 -12 MPH just with the steps and no additional power
